10Westpac New Zealand Limited

Note 1 Financial statements preparation
The Bank was incorporated as Westpac New Zealand Limited under the Companies Act 1993 (Company Number 1763882) on 14 February 2006.

The head office of the Bank is situated at Westpac on Takutai Square, 16 Takutai Square, Auckland 1010, New Zealand and the address for service

of process on the Bank is General Counsel, Legal, Westpac on Takutai Square, 53 Galway Street, Auckland 1010, New Zealand.

The Bank is a locally incorporated subsidiary of the Ultimate Parent Bank providing consumer and business banking to New Zealand customers.

The Ultimate Parent Bank has shares listed on the ASX and NZX, and is classified as a foreign exempt issuer under the NZX Listing Rules.

The financial statements are for the Banking Group.

These financial statements were authorised for issue by the Board of Directors of the Bank on 2 November 2025. The Board has the power to

amend and reissue the financial statements.

The material accounting policies are set out below and in the relevant notes to the financial statements. These policies have been consistently

applied to all the years presented, unless otherwise stated.

a. Basis of preparation

(i) Basis of accounting

These financial statements are general purpose financial statements prepared in accordance with:

●the requirements of the Financial Markets Conduct Act 2013; and

●the requirements of the Order.

These financial statements comply with New Zealand Generally Accepted Accounting Practice, applicable NZ IFRS and other authoritative

pronouncements of the XRB, as appropriate for for-profit entities. These financial statements also comply with International Financial Reporting

Standards Accounting Standards, as issued by the International Accounting Standards Board.

All amounts in these financial statements have been rounded to the nearest million dollars unless otherwise stated.

(ii) Historical cost convention

These financial statements have been prepared under the historical cost convention, as modified by applying fair value accounting to financial

assets and financial liabilities (including derivative instruments) measured at FVIS or FVOCI.

(iii) Comparative revisions

Comparative information has been revised where appropriate to conform to changes in presentation in the current year and to enhance

comparability. Where there has been a material restatement of comparative information the nature of, and the reason for, the restatement is

disclosed in the relevant section.

(iv) Standards adopted during the year ended 30 September 2025

No new accounting standards have been adopted by the Banking Group for the year ended 30 September 2025. There have been no amendments

to existing accounting standards that have had a material impact to the Banking Group.

(v) Business combinations

Business combinations are accounted for using the acquisition method of accounting. Acquisition cost is measured as the aggregate of the fair

value at the date of acquisition of the assets given, equity instruments issued or liabilities incurred or assumed. Acquisition-related costs are

expensed as incurred (except for those costs arising on the issue of equity instruments which are recognised directly in equity).

Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured at fair value on the

acquisition date. Goodwill is measured as the excess of the acquisition cost, the amount of any non-controlling interest and the fair value of any

previous Banking Group’s equity interest in the acquiree, over the fair value of the identifiable net assets acquired.

(vi) Foreign currency translation

Functional and presentation currency

The financial statements are presented in New Zealand dollars which is the Banking Group’s functional and presentation currency.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. FX

gains and losses resulting from the settlement of such transactions and from the translation at year end exchange rates of monetary assets and

liabilities denominated in foreign currencies are recognised in the income statement, except when deferred in OCI for qualifying cash flow hedges.

Notes to the financial statements

Westpac New Zealand Limited11

Note 1 Financial statements preparation (continued)
(vii) Reserves

Investment securities reserve

This comprises the changes in the fair value of debt securities measured at FVOCI (except for interest income, impairment charges and FX gains

and losses which are recognised in the income statement), net of any related hedge accounting adjustments and tax. These changes are

transferred to non-interest income in the income statement when the asset is disposed of.

Cash flow hedge reserve

This comprises the fair value gains and losses associated with the effective portion of designated cash flow hedging instruments, net of tax.

b. Principles of consolidation

The Banking Group subsidiaries are entities which the Bank controls and consolidates as it is exposed to, or has rights to, variable returns from its

involvement with the entities, and can affect those returns through its power over the entities.

All transactions between entities within the Banking Group are eliminated. Subsidiaries are fully consolidated from the date on which control

commences and are de-consolidated from the date that control ceases.

c. Financial assets and financial liabilities

(i) Recognition

Financial assets and financial liabilities, other than regular way transactions, are recognised when the Banking Group becomes a party to the terms

of the contract, which is generally on the settlement date (the date payment is made or cash advanced). Purchases and sales of financial assets in

regular way transactions are recognised on the trade date (the date on which the Banking Group commits to purchase or sell an asset).

(ii) Derecognition

Financial assets are derecognised when the rights to receive cash flows from the asset have expired, or when the Banking Group has either

transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full under a ‘pass through’

arrangement and transferred substantially all the risks and rewards of ownership.

There may be situations where the Banking Group has partially transferred the risks and rewards of ownership but has neither transferred nor

retained substantially all the risks and rewards of ownership. In such situations, the asset continues to be recognised on the balance sheet to the

extent of the Banking Group’s continuing involvement in the asset.

Financial liabilities are derecognised when the obligation is discharged, cancelled or expires. Where an existing financial liability is replaced by

another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, the exchange or

modification is treated as a derecognition of the original liability and the recognition of a new liability, with the difference in the respective carrying

amounts recognised in the income statement.

The terms are deemed to be substantially different if the discounted present value of the cash flows under the new terms (discounted using the

original effective interest rate) is at least 10% different from the discounted present value of the remaining cash flows of the original financial

liability. Qualitative factors such as a change in the currency the instrument is denominated in, a change in the interest rate from fixed to floating

and conversion features are also considered.

(iii) Classification and measurement basis

Financial assets

Financial assets are grouped into the following classes: cash and balances with central banks, collateral paid, trading securities and financial

assets measured at FVIS, derivative financial instruments, investment securities, loans, other financial assets and due from related entities.

Financial assets are classified based on a) the business model within which the assets are managed, and b) whether the contractual cash flows of

the instrument represent SPPI.

The Banking Group determines the business model at the level that reflects how groups of financial assets are managed. When assessing the

business model the Banking Group considers factors including how performance and risks are managed, evaluated and reported and the

frequency and volume of, and reason for, sales in previous periods and expectations of sales in future periods.

When assessing whether contractual cash flows are SPPI, interest is defined as consideration primarily for the time value of money and the credit

risk of the principal outstanding. The time value of money is defined as the element of interest that provides consideration only for the passage of

time and not consideration for other risks or costs associated with holding the financial asset. Terms that could change the contractual cash flows

so that they may not meet the SPPI criteria include contingent and leverage features, non-recourse arrangements, and features that could modify

the time value of money.

Debt instruments

If the debt instruments have contractual cash flows which represent SPPI on the principal balance outstanding they are classified at:

●amortised cost if they are held within a business model whose objective is achieved through holding the financial asset to collect these cash

flows; or

●FVOCI if they are held within a business model whose objective is achieved both through collecting these cash flows and selling the financial

asset; or

●FVIS if they are held within a business model whose objective is achieved through selling the financial asset.

Notes to the financial statements

12Westpac New Zealand Limited

Note 1 Financial statements preparation (continued)
Debt instruments are classified and measured at FVIS where the contractual cash flows do not represent SPPI on the principal balance outstanding

or where it is designated at FVIS to eliminate or reduce an accounting mismatch.

Debt instruments at amortised cost are initially recognised at fair value and subsequently measured at amortised cost using the effective interest

method. They are presented net of any provision for ECL determined using the ECL model. Refer to Notes 6 and 12 for further details.

Debt instruments at FVOCI are measured at fair value with unrealised gains and losses recognised in OCI except for interest income, impairment

charges and FX gains and losses, which are recognised in the income statement. Impairment on debt instruments at FVOCI is determined using

the ECL model and is recognised in the income statement with a corresponding amount in OCI. There is no reduction of the carrying value of the

debt security which remains at fair value.

The cumulative gain or loss recognised in OCI is subsequently recognised in the income statement when the instrument is derecognised.

Debt instruments at FVIS are measured at fair value with subsequent changes in fair value recognised in the income statement.

Financial liabilities

Financial liabilities are grouped into the following classes: collateral received, deposits and other borrowings, other financial liabilities, derivative

financial instruments, due to related entities, debt issues and loan capital.

Financial liabilities are measured at amortised cost if they are not held for trading or designated at FVIS, otherwise they are measured at FVIS.

Financial assets and financial liabilities measured at FVIS are recognised initially at fair value. All other financial assets and financial liabilities are

recognised initially at fair value plus or minus directly attributable transaction costs respectively.

Further details of the accounting policy for each category of financial asset or financial liability mentioned above are set out in the note for the

relevant item.

The Banking Group’s policies for determining the fair value of financial assets and financial liabilities are set out in Note 24.

d. Critical accounting assumptions and estimates

Applying the Banking Group’s accounting policies requires the use of judgement, assumptions and estimates which impact the financial

information. The significant assumptions and estimates used are discussed in the relevant notes below.

●Note 12Provision for expected credit losses

●Note 24Fair values of financial assets and financial liabilities

During the six months ended 31 March 2025, geopolitical developments, including in relation to international trade and tariff policies, global

tensions and continuing global military conflict, led to heightened uncertainty as to future economic forecasts and potential impact on the

Banking Group and its customers. Responding to this heightened uncertainty, the Banking Group increased the weighting of the downside

scenario used in the estimate of ECL from 42.5% to 45% in March 2025 (refer to Note 12 for further details). As at 30 September 2025, estimates of

ECL remain subject to this higher than usual level of uncertainty.

Impact of climate-related risks

The Banking Group has considered the potential risk of climate change on its financial statements. Refer to Note 31 for further details.

e. Future developments in accounting standards

NZ IFRS 9 Financial Instruments (NZ IFRS 9) became effective for the Banking Group for the financial year ended 30 September 2019. When

adopted, as permitted by the standard, the Banking Group elected to continue to comply with the hedge accounting requirements under NZ IAS

39 Financial Instruments: Recognition and Measurement (NZ IAS 39). The Banking Group intends to adopt the hedge accounting requirements of

NZ IFRS 9 prospectively for the financial year beginning 1 October 2025, for designated hedge relationships other than fair value hedges of the

interest rate exposure of a portfolio of financial assets or financial liabilities (fair value macro hedges) which will continue to be accounted for

under NZ IAS 39, as dynamic portfolio risk management is out of scope of NZ IFRS 9. All the Banking Group's existing hedge accounting

relationships will continue to qualify for hedge accounting. Under NZ IFRS 9, costs of hedging associated with cross currency basis risk will be

reflected in a new cost of hedging reserve (COHR). The quantum of this impact will be based on the valuation of derivatives at the time.

NZ IFRS 18 Presentation and Disclosure in Financial Statements (NZ IFRS 18) was issued in May 2024 and will be effective for the 30 September

2028 year end unless early adopted. NZ IFRS 18 will replace NZ IAS 1 Presentation of Financial Statements. This standard will not change the

recognition and measurement of items in the financial statements, but will impact the presentation and disclosure in the financial statements,

including:

●New categories and subtotals in the income statement to enhance comparability;

●Enhancing the disclosure of management defined performance measures; and

●Changes to the grouping of information in the financial statements to provide more useful information.

The Banking Group is continuing to assess the impact of adopting NZ IFRS 18.

Note 1 Financial statements preparation (continued)
Amendments to the Classification and Measurement of Financial Instruments was issued in June 2024 and amends NZ IFRS 7 Financial

Instruments: Disclosures and NZ IFRS 9 Financial Instruments. It is effective for the 30 September 2027 year end unless early adopted.

The amendments include:

●Changes to disclosures for investments in equity instruments designated at FVOCI and additional disclosures for financial instruments with

contingent features that do not relate directly to basic lending risks and costs;

●Guidance on derecognition of financial liabilities criteria when using an electronic payments system; and

●Guidance on assessing contractual cash flow characteristics of financial assets with ESG and similar features.

The Banking Group is continuing to assess the impact of adopting the amendments.

Other new standards and amendments to existing standards that are not yet effective are not expected to have a material impact on the Banking

Group.

Note 2 Net interest income
Accounting policy

Interest income and interest expense for all interest earning financial assets and interest bearing financial liabilities at amortised cost or FVOCI,

detailed within the table below, are recognised using the effective interest method. Net income from Treasury’s interest rate and liquidity

management activities and the cost of the Depositor Compensation Scheme levy are included in net interest income.

The effective interest method calculates the amortised cost of a financial instrument by discounting the financial instrument’s estimated future

cash receipts or payments to their present value and allocates the interest income or interest expense, including any fees, costs, premiums or

discounts integral to the instrument, over its expected life.

Interest income is calculated based on the gross carrying amount of financial assets in stages 1 and 2 of the Banking Group's ECL model and on

the carrying amount net of the provision for ECL for financial assets in stage 3.

Note 3 Non-interest income
Accounting policy

Non-interest income includes net fees and commissions income and other income.

Net fees and commissions income

When another party is involved in providing goods or services to a Banking Group customer, the Banking Group assesses whether the nature of

the arrangement with its customer is as a principal provider or an agent of another party. Where the Banking Group is acting as an agent for

another party, the income earned by the Banking Group is the net consideration received (i.e. the gross amount received from the customer less

amounts paid to a third party provider). As an agent, the net consideration represents fees and commissions income for facilitating the

transaction between the customer and the third party provider with primary responsibility for fulfilling the contract.

Fees and commissions income

Fees and commissions income is recognised when the performance obligation is satisfied by transferring the promised good or service to the

customer. Fees and commissions income includes facility fees, transaction fees and commissions and other non-risk fee income. Commissions

income includes commissions received for the distribution of general and life insurance products.

Facility fees include certain line fees, annual credit card fees and fees for providing customer bank accounts. They are recognised over the term

of the facility/period of service on a straight line basis.

Transaction fees and commissions are earned for facilitating banking transactions such as FX and telegraphic transfers. Fees and commissions

for these one-off transactions are recognised once the transaction has been completed. Transaction fees and commissions are also recognised

for credit card transactions including interchange fees net of scheme charges. These are recognised once the transaction has been completed,

however, a component of interchange fees received is deferred as unearned income as the Banking Group has a future service obligation to

customers under the Banking Group’s credit card reward programmes.

Other non-risk fee income includes advisory and underwriting fees which are recognised when the related service is completed.

Income which forms an integral part of the effective interest rate of a financial instrument is recognised using the effective interest method and

recorded in interest income (for example, loan origination fees).

Fees and commissions expenses

Fees and commissions expenses include incremental external costs that vary directly with the provision of goods or services to customers. An

incremental cost is one that would not have been incurred if a specific good or service had not been provided to a specific customer. Fees and

commissions expenses which form an integral part of the effective interest rate of a financial instrument are recognised using the effective

interest method and recorded in net interest income. Fees and commissions expenses include the costs associated with credit card loyalty

programmes which are recognised as an expense when the services are provided on the redemption of points.

Note 5 Auditor’s remuneration1

The disclosure of fees paid to the Banking Group’s external auditor has been revised to reflect the amendments to FRS-44 New Zealand Additional

Disclosures. Comparatives have been revised accordingly.

KPMG was appointed as the Banking Group's external auditor, beginning 1 October 2024. As a result, auditor's remuneration for the financial year

ended 30 September 2025 relates to fees for services provided by KPMG (KPMG New Zealand unless otherwise stated), whereas comparatives

reflect fees paid to PwC (PwC New Zealand unless otherwise stated). Amounts paid to PwC for services in the financial year ended 30 September

disclosures paid to PwC.

It is the Banking Group’s policy to engage the external auditor on assignments additional to their statutory audit duties only if their independence

is not impaired or seen to be impaired, and where their expertise and experience with the Banking Group is important.

Fees for the audit of the PIE Funds' (as defined in Note 22) financial statements for the year ended 30 September 2025 of $55,000 (30 September

2024: $36,383) were paid to PwC due to the timing of the external auditor transition, as the PIE Funds' balance date is 31 March. As PwC are not the

Banking Group's external auditor for the year ended 30 September 2025, this is not included in the table above.

Note 6 Impairment charges/(benefits)
Accounting policy

Impairment charges are based on an expected loss model which measures the difference between the current carrying amount and the present

value of expected future cash flows taking into account past experience, current conditions and multiple probability-weighted macroeconomic

scenarios for reasonably supportable future economic conditions. Further details of the calculation of ECL and the critical accounting

assumptions and estimates relating to impairment charges are included in Note 12.

Impairment charges are recognised in the income statement, with a corresponding amount recognised as follows:

●Loans at amortised cost: as a reduction of the carrying value of the financial asset through an offsetting provision account (refer to Note

12);

●Investment securities: in reserves in OCI with no reduction of the carrying value of the debt security (refer to the statement of changes in

equity); and

●Credit commitments: as a provision (refer to Note 19).

Uncollectable loans

A loan may become uncollectable in full or part if, after following the Banking Group’s loan recovery procedures, the Banking Group remains

unable to collect that loan’s contractual repayments. Uncollectable amounts are written off against their related provision for ECL, after all

possible repayments have been received.

Where loans are secured, amounts are generally written off after receiving the proceeds from the security, or in certain circumstances, where

the net realisable value of the security has been determined and this indicates that there is no reasonable expectation of full recovery, write-off

may be earlier. Unsecured consumer loans are generally written off after 180 days past due.

The Banking Group may subsequently be able to recover cash flows from loans written off. In the period which these recoveries are made, they

are recognised in the income statement.

Note 7 Income tax expense
Accounting policy

The income tax expense for the year comprises current and deferred tax. Tax is recognised in the income statement, except to the extent that it

relates to items recognised directly in OCI, in which case it is recognised in the statement of comprehensive income.

Current tax is the tax payable for the year using enacted or substantively enacted tax rates and laws. Current tax also includes adjustments to

tax payable for previous years.

Judgement is required in determining the current tax liability. There may be transactions with uncertain tax outcomes and provisions are

determined based on the expected outcomes.

Goods and services tax

Revenue, expenses and assets are recognised net of GST except to the extent that GST is not recoverable from the New Zealand Inland Revenue.

In these circumstances, GST is recognised as part of the expense or the cost of the asset.

Pillar Two introduces new 'top-up' taxes for multinational enterprises ('MNEs') within the scope of the rules to ensure that these MNEs pay a

minimum effective tax rate of 15% on profits in all jurisdictions.

The Banking Group is part of an MNE group under the Ultimate Parent Bank that falls within the Organisation for Economic Co-operation and

Development Pillar Two Model Rules. Pillar Two legislation has been enacted in New Zealand and will take effect from the Banking Group's financial

year beginning 1 October 2025. Based on an assessment of the most recent tax filings and financial statements for its constituent entities, the

Banking Group does not expect a material exposure, if any, to Pillar Two income taxes.

Note 9 Trading securities and financial assets measured at FVIS
Accounting policy

Trading securities and other financial assets measured at FVIS

Trading securities comprise actively traded debt (government and other) and those instruments acquired for sale in the near term. The

instruments are measured at fair value.

Other financial assets measured at FVIS include non-trading debt securities (government and other) managed on a fair value basis.

Reverse repurchase agreements

Securities purchased under these agreements are not recognised on the balance sheet, as the Banking Group has not obtained the risks and

rewards of ownership. The cash consideration paid is recognised as a reverse repurchase agreement, which forms part of a portfolio that is

measured at fair value.

Fair value gains and losses on these financial assets are recognised in the income statement. Interest earned from debt securities is recognised

in interest income (refer to Note 2).

Accounting policy

Investment securities include debt securities (government and other) that are measured at FVOCI. These instruments are classified based on the

Debt securities measured at FVOCI

Includes debt instruments that have contractual cash flows which represent SPPI on the principal balance outstanding and they are held within a

business model whose objective is achieved both through collecting these cash flows or selling the financial asset.

These securities are measured at fair value with unrealised gains and losses recognised in OCI except for interest income, impairment charges

and FX gains and losses and fair value hedge adjustments which are recognised in the income statement.

Impairment is measured using the same ECL model applied to financial assets measured at amortised cost. Impairment is recognised in the

income statement with a corresponding amount in OCI with no reduction of the carrying value of the debt security which remains at fair value.

Refer to Note 12 for further details.

The cumulative gain or loss recognised in OCI is subsequently recognised in the income statement when the instrument is disposed.

Accounting policy

Loans are financial assets initially recognised at fair value plus directly attributable transaction costs and fees.

Loans are subsequently measured at amortised cost using the effective interest method where they have contractual cash flows which represent

SPPI on the principal balance outstanding and they are held within a business model whose objective is achieved through holding the loans to

collect these cash flows. They are presented net of any provision for ECL.

Loan products that have both mortgage and deposit facilities are presented gross on the balance sheet, segregating the asset and liability

component, because they do not meet the criteria to be offset. Interest earned on these products is presented on a net basis in the income

statement as this reflects how the customer is charged.

Note 12 Provision for expected credit losses
Accounting policy

Note 6 provides details of impairment charges/(benefits).

Impairment applies to all financial assets at amortised cost, debt securities measured at FVOCI and credit commitments.

The ECL is recognised as follows:

●Loans: as a reduction of the carrying value of the financial asset through an offsetting provision account (refer to Note 11);

●Investment securities: in reserves in OCI with no reduction of the carrying value of the debt security itself (refer to the statement of

changes in equity); and

●Credit commitments: as a provision (refer to Note 19).

Measurement

The Banking Group calculates the provision for ECL based on a three stage approach. The provision for ECL is a probability-weighted estimate of

the cash shortfalls expected to result from defaults over the relevant timeframe. They are determined by evaluating a range of possible

outcomes and taking into account the time value of money, past events, current conditions and forecasts of future economic conditions.

The models use three main components to determine the ECL (as well as the time value of money) including:

●PD: the probability that a counterparty will default;

●LGD: the loss that is expected to arise in the event of a default; and

●EAD: the estimated outstanding amount of credit exposure at the time of the default.

Model stages

The three stages are as follows:

Stage 1: 12 months ECL - performing

For financial assets where there has been no significant increase in credit risk since origination a provision for 12 months ECL is recognised.

Stage 2: Lifetime ECL – performing

For financial assets where there has been a significant increase in credit risk since origination but where the asset is still performing a provision

for lifetime ECL is recognised. The indicators of a significant increase in credit risk are described on the following page.

Stage 3: Lifetime ECL – non-performing

Financial assets in Stage 3 are those that are in default. A default occurs when:

●The Banking Group considers that the customer is unable to repay its credit obligations in full, irrespective of recourse by the Banking

Group to action such as realising security. Indicators include a breach of contract with the Banking Group such as a default on interest or

principal payments, a borrower experiencing significant financial difficulties or observable economic conditions that correlate to defaults

on an individual basis; or

●The customer is more than 90 days past due on any material credit obligation.

A provision for lifetime ECL is recognised on these financial assets.

Collective and individual assessment

Financial assets that are in Stages 1 and 2 are assessed on a collective basis. This means that they are grouped in pools of similar assets with

similar credit risk characteristics including the type of product and CRG. Financial assets in Stage 3 are assessed on an individual basis and

calculated collectively for those below a specified threshold.

Expected life

In considering the lifetime timeframe for ECL in Stages 2 and 3, the standard generally requires use of the remaining contractual life adjusted,

where appropriate, for prepayments, extension and other options. For certain revolving credit facilities which include both a drawn and undrawn

component (e.g. credit cards and revolving lines of credit), the Banking Group’s contractual ability to demand repayment and cancel the

undrawn commitment does not limit the exposure to credit losses to the contractual notice period. For these facilities, lifetime is based on

historical behaviour.

Movement between stages

Financial assets may move in both directions through the stages of the impairment model. Financial assets previously in Stage 2 may move back

to Stage 1 if it is no longer considered that there has been a significant increase in credit risk. Similarly, financial assets in Stage 3 may move back

to Stage 1 or Stage 2 if they are no longer assessed to be non-performing.

Notes to the financial statements

22Westpac New Zealand Limited

Note 12 Provision for expected credit losses (continued)
Accounting policy (continued)

Critical accounting assumptions and estimates

Key judgements include when a significant increase in credit risk has occurred, the estimation of forward-looking macroeconomic information

and overlays. Other factors which can impact the provision include the borrower’s financial situation, the realisable value of collateral, the

Banking Group’s position relative to other claimants, the reliability of customer information and the likely cost and duration of recovering the

loan.

Significant increase in credit risk

Determining when a financial asset has experienced a significant increase in credit risk since origination is a critical accounting judgement which

is based on the change in the PD since origination. In determining whether a change in PD represents a significant increase in risk, relative

changes in PD and absolute PD thresholds are both considered based on the portfolio of the exposure.

The Banking Group does not rebut the presumption that instruments that are 30 days past due have experienced a significant increase in credit

risk, but this is used as a backstop rather than the primary indicator.

Forward-looking macroeconomic information

The measurement of ECL for each stage and the assessment of significant increase in credit risk consider information about past events and

current conditions as well as reasonable and supportable projections of future events and economic conditions. The estimation of forward-

looking information is a critical accounting judgement. The Banking Group considers three future macroeconomic scenarios including a base

case scenario along with upside and downside scenarios.

The macroeconomic variables used in these scenarios, based on current economic forecasts, include (but are not limited to) unemployment

rates, real GDP growth rates, base interest rates and residential property price indices.

●Base case scenario

This scenario utilises the internal Westpac Economic forecasts used for strategic decision making and forecasting.

●Upside scenario

This scenario represents a modest improvement on the base case scenario.

●Downside scenario

The downside scenario is a more severe scenario with ECL higher than those under the base case scenario. This scenario assumes a

recession with a combination of negative GDP growth, declines in residential property prices and an increase in the unemployment rate,

which simultaneously impact ECL across all portfolios from the reporting date.

The three macroeconomic scenarios are probability weighted and together represent the Banking Group’s view of the forward-looking

distribution of potential loss outcomes. The weighting applied to each of the three macroeconomic scenarios takes into account historical

frequency, current trends, and forward-looking conditions.

The macroeconomic variables and probability weightings of the three macroeconomic scenarios are subject to the approval of the Banking

Group’s Chief Financial Officer and Chief Risk Officer with oversight from the Board of Directors (and its Committees).

Portfolio overlays

Where appropriate, adjustments will be made to modelled outcomes to reflect reasonable and supportable information not already

incorporated in the models. These adjustments (overlays) may be an increase or decrease in the provision for ECL.

Judgements can change with time as new information becomes available which could result in changes to the provision for ECL.

●“Transfers between stages” represents transfers between Stage 1, Stage 2 and Stage 3 prior to remeasurement of the provision for ECL.

●“New facilities originated” represents new accounts originated during the year.

●“Facilities derecognised” represents loans derecognised due to final repayments during the year.

●“Other charges/(credits) to the income statement” represents the impact on the provision for ECL due to changes in credit quality during

the year (including transfers between stages), changes in portfolio overlays, changes in key economic assumptions and partial repayments

and additional drawdowns on existing facilities over the year.

●"Amounts written off" represents a reduction in the provision for ECL as a result of derecognition of exposures where there is no reasonable

expectation of full recovery.

Impact of overlays on the provision for ECL on loans and credit commitments

The following table attributes the provision for ECL on loans and credit commitments between individually assessed and collectively assessed

provisions. Collectively assessed provisions are disaggregated into the modelled ECL provision and portfolio overlays.

Portfolio overlays are used to capture areas of potential risks and uncertainties that are not captured in the underlying modelled ECL.

Details of changes related to forward-looking economic inputs and portfolio overlays, based on reasonable and supportable information up to the

date of this disclosure statement, are provided below.

(a) Modelled provision for ECL on loans and credit commitments

The modelled provision for ECL on loans and credit commitments is a probability weighted estimate based on three scenarios which together

represent the Banking Group’s view of the forward-looking distribution of potential loss outcomes. The changes in provisions as a result of

changes in modelled ECL are reflected through the “Other charges/(credits) to the income statement” line in the “Movements in components of

loss allowance” table. Overlays are used to capture potential risks and uncertainties that are not captured in the underlying modelled ECL.

The base case scenario uses the latest Westpac Economics forecast. Certain data points from this forecast are shown below:

The downside scenario is an economic downturn scenario with ECL higher than the base case. This scenario assumes a recession with a

combination of negative GDP growth, declines in residential property prices and an increase in the unemployment rate, which simultaneously

impact ECL across all portfolios from the reporting date. The assumptions used in this scenario and relativities to the base case will be monitored

having regard to the emerging economic conditions and updated where necessary. The upside scenario represents a modest economic

improvement to the base case.

The following sensitivity table shows the reported provision for ECL on loans and credit commitments based on the probability weighted scenarios

and what the provision for ECL on loans and credit commitments would be assuming a 100% weighting is applied to the base case scenario and to

the downside scenario (with all other assumptions held constant).

If 1% of the Stage 1 gross exposure from loans and credit commitments (calculated on a 12 month ECL) were transferred to Stage 2 (calculated on

a lifetime ECL) the provision for ECL on loans and credit commitments would increase by $17 million (30 September 2024: $14 million). If 1% of

Stage 2 loans and credit commitments (calculated on a lifetime ECL) were transferred to Stage 1 (calculated on a 12 month ECL), the provision for

ECL on loans and credit commitments would decrease by $2 million (30 September 2024: $3 million) for the Banking Group. These estimates apply

the average modelled provision coverage ratio by stage to the transfer of loans and credit commitments.

(b) Portfolio overlays

Portfolio overlays are used to address areas of risk, including significant uncertainties that are not captured in the underlying modelled ECL. These

risks may result in under or overestimation of the modelled provision for ECL. Determination of portfolio overlays requires expert judgement and is

thoroughly documented and subject to comprehensive internal governance and oversight. Portfolio overlays are continually reassessed and if the

risk is judged to have changed (increased or decreased), or is subsequently captured in the modelled ECL, the portfolio overlays will be released

or remeasured.

The Banking Group’s total portfolio overlays as at 30 September 2025 were $(27) million (30 September 2024: $(33) million), held on the provision

for ECL for residential mortgages to adjust for observed conservatism in the modelled outcome identified through model monitoring.

Impact of changes in gross carrying amount on the provision for ECL

●Stage 1 gross carrying amount had a net increase of $12.3 billion (30 September 2024: increased by $3.5 billion), primarily driven by new

lending and underlying portfolio movement from residential mortgages and corporate lending, partially offset by repayments. The Stage 1

ECL increase is in line with Stage 2 exposures movement to Stage 1, primarily driven by underlying portfolio movements and a more positive

economic outlook, partially offset by higher downside scenario weightings.

●Stage 2 gross carrying amount decreased by $8.2 billion (30 September 2024: decreased by $0.9 billion), primarily driven by the movement

of exposures to Stage 1, repayments and underlying portfolio movement from residential mortgages and corporate lending. The Stage 2 ECL

decrease is mainly as a result of the movement of exposures to Stage 1, primarily driven by underlying portfolio movements and an

improved economic outlook, partially offset by the increase in downside scenario weightings from residential mortgages and corporate

lending.

●Stage 3 gross carrying amount increased by $0.1 billion (30 September 2024: increased by $0.2 billion), driven by increases in 90 days past

due exposures from the residential mortgages lending, partially offset by repayments and releases due to write-offs from other retail

lending. The Stage 3 ECL increase is in line with the increase in Stage 3 exposures.

Refer to Note iii. Asset quality of the Registered bank disclosures for further details.

Write-offs still under enforcement activity

The amount of current year write-offs which remain subject to enforcement activity was $25 million (30 September 2024: $30 million).

Please refer to Note 31.1 for details of the Banking Group’s overall Risk Management Framework.

●The Banking Group maintains a Credit Risk Management Framework, a Credit Risk Management Strategy, and a Credit Risk Appetite

Statement, and a number of supporting policies that define roles and responsibilities, acceptable practices, limits and key controls.

●The Banking Group’s Credit Risk Management Framework describes the principles, methodologies, systems, roles and responsibilities,

reports and key controls for managing credit risk.

●The BRCC, RISKCO and CREDCO monitor the risk profile, performance and management of the Banking Group’s credit portfolio on at least a

quarterly basis, and the development and review of key credit risk policies on at least an annual basis; other management reviews occur

monthly or more frequently.

●The Banking Group’s Credit Risk Rating System Policy describes the credit risk rating system philosophy, design, key features and uses of

rating outcomes.

●All models materially impacting the risk rating process are periodically reviewed in accordance with the Banking Group’s model risk policies.

●An annual review is performed of the Credit Risk Rating System for approval by the Banking Group’s Chief Risk Officer and noting by the

BRCC. The Credit Risk Rating System Policy is annually approved by the BRCC.

●Specific credit risk estimates (including PD, LGD and EAD) are reviewed by CREDCO and are overseen, reviewed annually and approved by

the Banking Group’s Chief Risk Officer.

●In determining the provision for ECL, the forward-looking economic inputs and the probability weightings of the forward-looking scenarios

as well as any adjustments made to the modelled outcomes are subject to the approval of the Banking Group’s Chief Financial Officer and

the Chief Risk Officer with oversight from the Board (and its Committees).

●Policies for delegating credit approval authorities and formal limits for the extension of credit are established throughout the Banking Group.

●Credit policies are established and maintained throughout the Banking Group. They include policies governing the origination, evaluation,

approval, documentation, settlement and ongoing management of credit risks.

●Sector policies guide credit extension where industry-specific guidelines are considered necessary (e.g. acceptable financial ratios o r

permitted collateral).

●The Ultimate Parent Bank’s Related Entity Risk Management Policy and supporting policies govern credit exposures to related entities to

minimise the spread of credit risk between the Ultimate Parent Bank Group entities to comply with the Ultimate Parent Bank’s prudential

requirements prescribed by APRA.

●Climate change-related credit risks are considered in line with the Ultimate Parent Bank’s Climate Change Position Statement and Action

Plan. Climate change risks are managed in line with the Banking Group’s Risk Management Framework which is supported by the Banking

Group’s Sustainability Risk Management Framework, the Bank's Climate Risk Policy, the Banking Group’s ESG Credit Risk Policy and the

Bank’s Board Risk Appetite Statements. Where appropriate, these are applied at the portfolio, customer, and transaction level.

●CREDCO oversees work to identify and manage the potential impact on credit exposures from climate change-related transition and

physical risks across the Banking Group.

●The Banking Group’s ESG Credit Risk Policy details the overall approach to managing ESG risks in the credit risk process for applicable

transactions.

Note 13 Credit risk management (continued)
13.2 Credit risk ratings system

The principal objective of the credit risk rating system is to reliably assess the credit risk to which the Banking Group is exposed. The Banking

Group has two main approaches to this assessment:

Transaction-managed customers

Transaction managed customers are generally customers with business lending exposures. They are individually assigned a CRG, corresponding to

their expected PD. Each facility is assigned an LGD. The Banking Group’s risk rating system has a tiered scale of risk grades for both non-defaulted

customers and defaulted customers. Non-defaulted CRGs are mapped to Moody's and S&P external senior ranking unsecured ratings.

The following table shows the Banking Group’s high level CRGs for transaction-managed portfolios mapped to the Banking Group’s credit quality

disclosure categories and to their corresponding external rating.

Banking Group Rating

WeakEWatchlist

FSpecial Mention

GSubstandard/Default

HDoubtful/Default

Program-managed portfolio

The program-managed portfolio generally includes retail products such as mortgages, personal lending (including credit cards) and certain SME

lending. These credit exposures are grouped into pools of similar risk based on analysis of characteristics that have historically predicted the

likelihood of default, and a PD is assigned relative to the credit exposure's pool. The exposure is then assigned to strong, good/satisfactory or weak

by benchmarking that PD against the Banking Group's CRGs, which are in turn mapped to external ratings as per the above table. In addition, any

program-managed exposures that are past due are classified as weak.

13.3 Credit risk concentrations and maximum exposure to credit risk

Credit risk is concentrated when a number of counterparties are engaged in similar activities, or have similar economic characteristics, and thus

may be similarly affected by changes in economic or other conditions.

The Banking Group monitors its credit portfolio to allow it to manage risk concentrations and rebalance the portfolio.

Individual customers or groups of related customers

The Banking Group has large exposure limits governing the aggregate size of credit exposure normally acceptable to individual customers and

groups of related customers. These limits are tiered by CRG.

Specific industries

Exposures to businesses, governments and other financial institutions are classified into a number of industry clusters based on related ANZSIC

codes and are monitored against the Banking Group’s industry risk appetite limits.

Individual countries

The Banking Group has limits governing risks related to individual countries, such as political situations, government policies and economic

conditions that may adversely affect either a customer’s ability to meet its obligations to the Banking Group, or the Banking Group’s ability to

realise its assets in a particular country.

This credit quality disclosure differs to that of credit concentration (refer to Note 13.3) as it relates only to financial assets measured at amortised costs or at FVOCI

and therefore excludes trading securities and financial assets measured at FVIS, and derivative financial instruments.

Comparatives have been revised to remove credit exposures offered and accepted but still revocable.

Details of collateral held in support of these balances are provided in Note 13.5.

Notes to the financial statements

Westpac New Zealand Limited33

Note 13 Credit risk management (continued)
13.5 Credit risk mitigation, collateral and other credit enhancements

The Banking Group uses a variety of techniques to reduce the credit risk arising from its lending activities.

This includes the Banking Group having processes in place to ensure that it has direct, irrevocable and unconditional recourse to collateral and

other credit enhancements through obtaining legally enforceable documentation.

The Banking Group includes the effect of credit risk mitigation through eligible guarantees within the calculation applied to LGD. Due to system

limitations, the value of the guarantee is not always separately recorded, and therefore, neither this value nor a close alternative is available for

disclosure under Clause 7 of Schedule 11 to the Order.

Collateral

The table below describes the nature of collateral or security held for each relevant class of financial asset:

Loans – residential mortgages

1

Housing loans are secured by a mortgage over property and additional security may take the

form of guarantees and deposits.

Loans – other retail

1

Personal lending (including credit cards and overdrafts) is predominantly unsecured. Where

security is taken, it is restricted to eligible motor vehicles, caravans, campers, motor homes

and boats.

SME loans may be secured, partially secured or unsecured. Security is typically taken by way

of a mortgage over property and/or a general security agreement over business assets or

other assets.

Loans – corporate

1

Business loans may be secured, partially secured or unsecured. Security is typically taken by

way of a mortgage over property and/or a general security agreement over business assets

or other assets.

Other security such as guarantees or standby letters of credit may also be taken as collateral,

if appropriate.

Trading securities and financial assets

measured at FVIS, due from related entities

and derivative financial instruments

These exposures are carried at fair value which reflects the credit risk.

For trading securities, no collateral is sought directly from the issuer or counterparty;

however this may be implicit in the terms of the instrument (such as an asset-backed

security). The terms of debt securities may include collateralisation.

Master netting agreements are typically used to enable the effects of derivative assets and

derivative liabilities with the same counterparty to be offset when measuring these

exposures. Additionally, collateralisation agreements are also typically entered into with

major institutional counterparties to avoid the potential build-up of excessive mark-to-

market positions.

1

This includes collateral held in relation to associated credit commitments.

Notes to the financial statements

34Westpac New Zealand Limited

Note 13 Credit risk management (continued)
Management of risk mitigation

The Banking Group mitigates credit risk through controls covering:

Collateral and valuation

management

The Ultimate Parent Bank manages collateral under collateralisation agreements centrally for all

branches of the Ultimate Parent Bank and the Bank.

The Banking Group revalues collateral related to financial markets positions on a daily basis and has

formal processes in place to promptly call for collateral top-ups, if required. These processes include

margining for non-centrally cleared customer derivatives where required under APRA Prudential

Standard CPS226. The collateralisation arrangements are documented via the Credit Support Annex of

the International Swaps and Derivatives Association dealing agreements and Global Master

Repurchase Agreements for repurchase transactions.

The estimated realisable value of collateral held in support of loans is based on a combination of:

●formal valuations currently held for such collateral; and

●management’s assessment of the estimated realisable value of all collateral held.

This analysis also takes into consideration any other relevant knowledge available to management at

the time. Updated valuations are obtained when appropriate.

Other credit enhancements

The Banking Group only recognises guarantees, standby letters of credit, or credit derivative

protection from entities meeting minimum eligibility requirements (provided they are not related to

the entity with which the Banking Group has a credit exposure) including but not limited to:

●Sovereign;

●Australia and New Zealand public sector;

●Authorised deposit-taking institutions and overseas banks with a minimum risk grade equivalent

of A3 / A-; and

●Other entities with a minimum risk grade equivalent of A3 / A-.

Credit Portfolio Management manages the Banking Group’s corporate, sovereign and bank credit

portfolios through monitoring the exposure and any offsetting hedge positions.

Offsetting

Creditworthy customers domiciled in New Zealand may enter into formal agreements with the Banking

Group, permitting the Banking Group to set-off gross credit and debit balances in their nominated

accounts. Cross-border set-offs are not permitted.

Close-out netting is undertaken with counterparties with whom the Banking Group has entered into a

legally enforceable master netting agreement for their off-balance sheet financial market transactions

in the event of default.

Further details of offsetting are provided in Note 25.

Central clearing

The Banking Group increasingly executes derivative transactions through central clearing

counterparties. Central clearing counterparties mitigate risk through stringent membership

requirements, the collection of margin against all trades placed, the default fund, and an explicitly

defined order of priority of payments in the event of default.

Collateral held against loans

The Banking Group analyses the coverage of the loan portfolio which is secured by the collateral that it holds. Coverage is measured as follows:

CoverageSecured loan to collateral value ratio

Fully securedLess than or equal to 100%

Partially securedGreater than 100% but not more than 150%

Unsecured

Greater than 150%, or no security held (e.g. can include credit cards, personal loans, and exposure to highly rated

corporate entities)

Note 14 Deferred tax assets
Accounting policy

Deferred tax accounts for temporary differences between the carrying amounts of assets and liabilities in the financial statements and their

values for taxation purposes.

Deferred tax is determined using the enacted or substantively enacted tax rates and laws which are expected to apply when the assets will be

realised or the liabilities settled.

Deferred tax assets and liabilities have been offset where they relate to the same taxation authority, the same taxable entity or group and where

there is a legal right and intention to settle on a net basis.

Deferred tax assets are recognised to the extent that it is probable that future taxable profits will be available to utilise the assets.

Deferred tax is not recognised for the following temporary differences:

●the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither the accounting nor

taxable profit or loss; and

●the initial recognition of goodwill in a business combination.

Note 15 Intangible assets
Accounting policy

Indefinite life intangible assets

Goodwill

Goodwill acquired in a business combination is initially measured at cost, being the excess of the consideration paid, over the net fair value of

the identifiable assets, liabilities and contingent liabilities acquired.

Subsequently, goodwill is not amortised but rather tested for impairment. Impairment is tested at least annually or whenever there is an

indication of impairment. An impairment charge is recognised when a CGU’s carrying value exceeds its recoverable amount. Recoverable

amount means the higher of the CGU’s fair value less costs to sell and its value-in-use.

The Banking Group’s CGUs represent the smallest identifiable group of assets that generate cash inflows that are largely independent of the cash

inflows from other assets or group of assets. They reflect the level at which the Banking Group monitors and manages its operations.

Finite life intangible assets

Finite life intangibles such as computer software which are recognised initially at cost and subsequently at amortised cost less any impairment.

Impairment

When assessing impairment of intangible assets, judgement is needed to determine the appropriate cash flows and discount rates to be applied

to the calculations. The assumptions applied to the value-in-use calculations are outlined below.

Goodwill has been allocated to the Consumer Banking and Wealth CGU, which is a single CGU.

Impairment testing and results

Impairment testing is performed at least once a year, or whenever there is an indication of impairment, by comparing the recoverable amount of

each CGU with the carrying amount. The primary test for the recoverable amount is determined based on value-in-use which refers to the present

value of expected cash flows under its current use.

Impairment testing in the current year confirmed that the Banking Group continues to have considerable headroom when determining whether

goodwill is recoverable, and no impairment should be recognised.

Assumptions used in recoverable amount calculations

The assumptions made for goodwill impairment testing for the Consumer Banking and Wealth CGU are provided in the following table and are

based on past experience and management’s expectations for the future. In the current year and given the present economic environment, the

Banking Group has reassessed these assumptions and revised them where necessary in order to provide a reasonable estimate of the value-in-use

of the CGU.

The Banking Group discounts the projected cash flows by the adjusted pre-tax equity rate.

The cashflows used are based on management approved forecasts. These forecasts utilise information about current and future economic

conditions, observable historical information and management expectations of future business performance. The terminal value growth rate

represents the growth rate applied to extrapolate cash flows beyond the forecast period and reflects the midpoint of the Reserve Bank’s inflation

target over the medium term.

There are no reasonably possible changes in assumptions for Consumer Banking and Wealth CGU that would result in an indication of impairment

or have a material impact on the Banking Group’s reported results.

Notes to the financial statements

Note 16 Deposits and other borrowings
Accounting policy

Deposits and other borrowings are initially recognised at fair value and subsequently either measured at amortised cost using the effective

interest method or at fair value.

Deposits and other borrowings are designated at fair value if they are managed on a fair value basis, reduce or eliminate an accounting

mismatch, or contain an embedded derivative.

Where they are measured at fair value, any changes in fair value (except those due to changes in credit risk) are recognised in the income

statement. The change in the fair value that is attributable to changes in credit risk is recognised in OCI except where it would create an

accounting mismatch, in which case it is also recognised in the income statement.

Interest expense incurred for deposits and other borrowings at amortised cost is recognised in net interest income using the effective interest

method.

Non-interest bearing relates to instruments which do not carry an entitlement to interest.

Note 17 Other financial liabilities

Accounting policy

Other financial liabilities include liabilities measured at amortised cost as well as liabilities which are measured at FVIS. Financial liabilities

measured at FVIS include liabilities designated at FVIS (i.e. certain repurchase agreements).

Repurchase agreements

Where securities are sold subject to an agreement to repurchase at a predetermined price, they remain recognised on the balance sheet in their

original category (i.e. trading securities and financial assets measured at FVIS or investment securities).

The cash consideration received is recognised as a liability (repurchase agreements). Repurchase agreements are designated at fair value where

this eliminates or significantly reduces an accounting mismatch or they are part of a group of instruments that are managed on a fair value basis.

Otherwise they are measured on an amortised cost basis.

Where a repurchase agreement is designated at fair value, any changes in fair value (except those due to change in credit risk) are recognised in

the income statement as they arise. The change in fair value that is attributable to credit risk is recognised in OCI except where it would create

an accounting mismatch in which case it is also recognised in the income statement.

Accounting policy

Debt issues are bonds, notes and commercial paper that have been issued by the Banking Group.

Debt issues are initially measured at fair value and subsequently either measured at amortised cost using the effective interest method or at fair

value.

Debt issues are designated at fair value if they reduce or eliminate an accounting mismatch or contain an embedded derivative.

Where they are measured at fair value, any changes in fair value (except those due to changes in credit risk) are recognised in the income

statement. The change in the fair value that is attributable to changes in credit risk is recognised in OCI except where it would create an

accounting mismatch, in which case it is also recognised in the income statement.

Interest expense incurred is recognised within net interest income using the effective interest method.

Note 19 Provisions
Accounting policy

Provisions are recognised for present obligations arising from past events where a payment (or other economic transfer) is likely to be necessary

to settle the obligation and can be reliably estimated.

Employee benefits – annual leave and other employee benefits

The provision for annual leave and other employee benefits (including long service leave, wages and salaries, inclusive of non-monetary benefits,

and any associated on-costs (e.g. payroll tax)) is calculated based on expected payments.

Provision for ECL on credit commitments

The Banking Group is committed to provide facilities and guarantees as explained in Note 26. If it is probable that a facility will be drawn and the

resulting asset will be less than the drawn amount then a provision for impairment is recognised. The provision for impairment is calculated

using the same methodology as the provision for ECL (refer to Note 12).

Compliance, regulation and remediation provisions

The compliance, regulation and remediation provisions relate to matters pertaining to the provision of services to our customers identified both

as a result of regulatory action and internal reviews. An assessment of the likely cost to the Banking Group of these matters (including applicable

customer refunds) is made on a case-by-case basis and specific provisions are made where appropriate.

The movement in the provision for ECL on credit commitments is presented on a net basis as either an addition for an increase or reversal of unutilised provision for

a decrease. Refer to Note 12 for further details.

Compliance, regulation and remediation provisions

The compliance, regulation and remediation provisions relate to matters pertaining to the provision of services to our customers identified as a

result of regulatory action and internal reviews, including the Banking Group’s review of processes for some products relating to the requirements

of the CCCFA.

All potential claims and other liabilities are assessed on a case-by-case basis. A provision has been recognised where the Banking Group has

conducted an assessment which determines the likelihood of loss as probable and where its potential loss can be reliably estimated.

A number of different estimates and judgements have been applied in measuring the provision at 30 September 2025, including the number of

impacted customers, the refund per customer and the additional costs to run the remediation programme. It is possible that the actual outcome

for these matters may differ from the assumptions used in estimating the provision. Remediation processes may change over time as further facts

emerge and such changes could result in a change to the final exposure.

Where a provision has not been recognised, a contingent liability may exist. Refer to Note 26 for further details on contingent liabilities.

Ranking and rights in liquidation

The AT1 notes were issued by the Bank and, in a liquidation of the Bank, rank equally amongst themselves and the Bank's AT1 PPS, are

subordinated to the claims of depositors and senior or less subordinated creditors of the Bank, and rank ahead of the Bank’s ordinary shares.

Transitional phase-out schedule

In accordance with BPR110 Capital definitions, the Bank’s AT1 notes are subject to a transitional phase-out from 1 January 2022 until 1 July 2028,

with the maximum eligible amount declining by 12.5% each year, and completely phased out from 1 July 2028. The base amount was fixed at the

total nominal amount of the Bank’s AT1 notes outstanding as at 30 September 2021, being $1,500 million. The total value able to be recognised as

AT1 is set out in BPR110 Capital definitions, with the lower of the outstanding amount or 50% of the base amount able to be recognised between 1

January 2025 and 31 December 2025 (30 September 2024: 62.5% between 1 January 2024 and 31 December 2024) in line with the phase-out

schedule. On 21 December 2023, the Bank exercised its option, for regulatory reasons, to redeem $1,000 million of the AT1 notes for their face

value, as approved by the Reserve Bank. As at 30 September 2025, the remaining outstanding amount of $500 million is fully recognised as AT1 in

accordance with the transitional phase-out schedule.

Interest payable

Quarterly interest payments on the AT1 notes are payable at the absolute discretion of the Bank and will only be paid if the payment conditions are

satisfied, including that the interest payment will not result in the Bank becoming insolvent immediately following the interest payment; not result

in a breach of the Reserve Bank's BPR; and the payment date not falling on the date of a capital trigger event or non-viability trigger event. Interest

payments are non-cumulative. If interest is not paid in full, the Bank may not determine or pay any dividends on its ordinary shares or undertake a

discretionary buy back or capital reduction of the Bank’s ordinary shares (except in limited circumstances).

Notes to the financial statements

42Westpac New Zealand Limited

Note 20 Loan capital (continued)
Redemption

The Bank may elect to redeem all or some of the AT1 notes for their face value on 21 September 2027 and every fifth anniversary thereafter, subject

to the Reserve Bank’s prior written approval. Early redemption of all or some of the AT1 notes for certain tax or regulatory reasons is permitted

subject to the Reserve Bank’s prior written approval.

Conversion

If a capital trigger event or non-viability trigger event occurs, the Bank must convert some or all of the AT1 notes into a variable number of ordinary

shares issued by the Bank (calculated with reference to the net assets of the Bank and the total number of ordinary shares on issue at the

conversion date) that is sufficient, in the case of a capital trigger event, to return the Bank’s Common Equity Tier 1 capital ratio to above 5.125% as

determined by the Bank in consultation with the Reserve Bank; or, in the case of a non-viability trigger event, to satisfy the direction of the Reserve

Bank or the decision of the statutory manager of the Bank. A capital trigger event occurs when the Bank determines, or the Reserve Bank notifies in

writing that it believes, the Bank’s Common Equity Tier 1 capital ratio is equal to or less than 5.125%. A non-viability trigger event occurs when the

Reserve Bank or the statutory manager (appointed pursuant to section 117 of the Banking (Prudential Supervision) Act 1989) directs the Bank to

convert or write off all or some of its AT1 notes.

If conversion of the AT1 notes does not occur within five business days of a capital trigger event or a non-viability trigger event, holders’ rights in

relation to the AT1 notes will be immediately and irrevocably terminated.

The Bank is able to elect to convert all the AT1 notes for certain tax or regulatory reasons (or in certain other circumstances).

Ranking and rights in liquidation

The subordinated notes were issued by the Bank and, in a liquidation of the Bank, the 2022 and 2023 subordinated notes rank equally with each

other and amongst themselves, are subordinated to the claims of depositors and senior or less subordinated creditors of the Bank, and rank

ahead of the AT1 notes, AT1 PPS and the Bank's ordinary shares.

Common features of subordinated notes

Interest payable

Quarterly interest payments on the subordinated notes are subject to the Bank being solvent at the time of, and immediately following, the

interest payment.

Early redemption

The Bank may elect to redeem all or some of the 2022 or 2023 subordinated notes for their face value together with accrued interest (if any) on an

optional redemption date for the series specified above, subject to the Reserve Bank’s prior written approval. Early redemption of all of the 2022

or 2023 subordinated notes for certain tax or regulatory reasons is permitted on an interest payment date subject to the Reserve Bank’s prior

written approval.

On 21 December 2023, the Bank issued two classes of AT1 PPS to the NZ Branch, totalling $1,000 million ('Internal PPS').

On 13 September 2024, the Bank issued $375 million of AT1 PPS, which are quoted on the NZX Debt Market ('Quoted PPS').

The AT1 PPS qualify as AT1 under the Reserve Bank’s capital adequacy framework. The AT1 PPS are classified as equity instruments as there is no

contractual obligation for the Banking Group to either deliver cash or another financial instrument or to exchange financial instruments on a

potentially unfavourable basis.

Ranking and rights in liquidation

The AT1 PPS were issued by the Bank and, in a liquidation of the Bank, rank equally amongst themselves and the Bank’s AT1 notes, are

subordinated to the claims of depositors and other creditors of the Bank (including holders of Tier 2 loan capital), and rank ahead of the Bank’s

ordinary shares. The AT1 PPS do not carry any voting rights.

AT1 PPS distributions payable

Quarterly AT1 PPS distributions are payable at the absolute discretion of the Bank. In addition, AT1 PPS distributions will only be paid if the Bank is

solvent on the payment date and remains solvent immediately after such payment is made and the payment will not result in a breach of the

Bank’s conditions of registration as at the time of the payment.

AT1 PPS distributions are non-cumulative. In respect of a class of AT1 PPS, if an AT1 PPS distribution is not paid in full, the Bank may not determine

or pay any dividends on its ordinary shares or undertake a discretionary buy-back or capital reduction of the Bank’s ordinary shares until a

subsequent AT1 PPS distribution is paid in full on that class (except in limited circumstances).

The Bank paid quarterly AT1 PPS distributions on the Internal PPS and the Quoted PPS as set out in the table below:

Note 22 Related entities (continued)
Nature of transactions

The Banking Group has transactions with members of the Ultimate Parent Bank Group on commercial terms, including the provision of

management, distribution and administrative services.

Loan finance and current account banking facilities are provided by the Ultimate Parent Bank to members of the Banking Group on normal

commercial terms. The interest earned on these loans and the interest paid on deposits are at market rates.

The NZ Branch provides financial market services, foreign currency, trade and interest rate risk products to the Banking Group and its customers,

which includes derivative transactions (refer to Note 23).

Effective 1 October 2014, the Bank and the NZ Branch entered into an agreement whereby the Bank will reimburse the NZ Branch for any credit

losses incurred by it due to certain customers of the Bank defaulting on certain financial market and international products. The Banking Group

receives commission from the sale of these products to customers for providing this guarantee.

This is treated as a financial guarantee for accounting purposes. Financial guarantee contracts are recognised as financial liabilities (recorded

within provisions) when a payment under a contract has become probable. The liability is initially measured at fair value and subsequently at the

higher of the amount of the loss allowance determined in accordance with NZ IFRS 9 and the amount initially recognised less, when appropriate,

the cumulative amount of income recognised.

The value of the exposures guaranteed at 30 September 2025 is $1,109 million (30 September 2024: $843 million), for which a liability has been

recognised of $7 million (30 September 2024: $4 million).

Share-based payments are amortised over the performance and deferral period (between two to five years). This includes restricted shares, hurdled share rights

and unhurdled share rights granted during the relevant periods up to 30 September 2025, which are calculated based on their fair value at the grant date (which is

the invitation opt out date). The fair value for hurdled and unhurdled share rights is determined using an external valuation.

The Directors have received remuneration from the Banking Group and these amounts are included in the table above.

Loans and deposits with key management personnel

All loans and deposits are made in the ordinary course of business of the Banking Group. Loans are on terms that range between variable, fixed

rate up to five years and interest only loans, all of which are in accordance with the Banking Group’s lending policies.

As at 30 September 2025, no amounts have been written off and no individual provision has been recognised in respect of loans given to key

management personnel and their related parties (30 September 2024: nil). These loans have been included within the loan portfolio when

determining collectively assessed provisions.

Other key management personnel transactions

All other transactions with key management personnel, their related entities and other related parties are conducted in the ordinary course of

business. These transactions principally involve the provision of financial, investment and insurance services.

Note 23 Derivative financial instruments
Accounting policy

Derivative financial instruments are instruments whose values are derived from the value of an underlying asset, reference rate or index and

include forwards, futures, swaps and options. Derivatives with related parties are included in due from/due to related entities.

The Banking Group uses derivative financial instruments for our ALM activities.

Trading derivatives

Derivatives which are used in our ALM activities but are not designated into a hedge accounting relationship are considered economic hedges.

These derivatives are measured at FVIS and are disclosed as trading derivatives in this note.

Hedging derivatives

Hedging derivatives are those which are used in our ALM activities and have also been designated into one of two hedge accounting

relationships: fair value hedge; or cash flow hedge. These derivatives are measured at fair value. These hedge designations and the associated

accounting treatment are detailed below.

For more details regarding the Banking Group’s ALM activities, refer to Note 31.

Fair value hedges

Fair value hedges are used to hedge the exposure to changes in the fair value of an asset or liability.

Changes in the fair value of derivatives and the hedged asset or liability in fair value hedges are recognised in non-interest income. The carrying

value of the hedged asset or liability is adjusted for the changes in fair value related to the hedged risk.

If a hedge is discontinued, any fair value adjustments to the carrying value of the asset or liability are amortised to net interest income over the

period to maturity. If the asset or liability is sold, any unamortised adjustment is immediately recognised in net interest income.

Cash flow hedges

Cash flow hedges are used to hedge the exposure to variability of cash flows attributable to an asset, liability or future forecast transaction.

For effective hedges, changes in the fair value of derivatives are recognised in the cash flow hedge reserve through OCI and subsequently

recognised in net interest income when the cash flows attributable to the asset or liability that was hedged impact the income statement.

For hedges with some ineffectiveness, the changes in the fair value of the derivatives relating to the ineffective portion are immediately

recognised in non-interest income.

If a hedge is discontinued, any cumulative gain or loss remains in OCI. It is amortised to net interest income over the period which the asset or

liability that was hedged also impacts the income statement.

If a hedge of a forecast transaction is no longer expected to occur, any cumulative gain or loss in OCI is immediately recognised in net interest

income.

Note 23 Derivative financial instruments (continued)
Hedge accounting

The Banking Group designates derivatives into hedge accounting relationships in order to manage the volatility in earnings and capital that would

otherwise arise from interest rate and FX risks that may result from differences in the accounting treatment of derivatives and underlying

exposures. These hedge accounting relationships and the risks they are used to hedge are described below.

The Banking Group enters into one-to-one hedge relationships to manage specific exposures where the terms of the hedged item significantly

match the terms of the hedging instrument. The Banking Group also uses dynamic hedge accounting where the hedged items are part of a

portfolio of assets and/or liabilities that frequently change. In this hedging strategy, the exposure being hedged and the hedging instruments may

change frequently rather than there being a one-to-one hedge accounting relationship for a specific exposure.

Fair value hedges

Interest rate risk

The Banking Group hedges its interest rate risk to reduce exposure to changes in fair value due to interest rate fluctuations over the hedging

period. Interest rate risk arising from fixed rate debt issuances and fixed rate bonds classified as investment securities at FVOCI is hedged with

single currency fixed to floating interest rate derivatives. The Banking Group also hedges its benchmark interest rate risk from fixed rate foreign

currency denominated debt issuances using cross currency swaps. In applying fair value hedge accounting the Banking Group primarily uses one-

to-one hedge accounting to manage specific exposures.

The Banking Group also uses a dynamic hedge accounting strategy for fair value portfolio hedge accounting of some fixed rate mortgages to

reduce exposure to changes in fair value due to interest rate fluctuations over the hedging period. These fixed rate mortgages are allocated to

time buckets based on their expected repricing dates and the fixed-to-floating interest rate derivatives are designated according to the capacity in

the relevant time buckets.

The Banking Group hedges the benchmark interest rate which generally represents the most significant component of the changes in fair value.

The benchmark interest rate is a component of interest rate risk that is observable in the relevant financial markets, for example, Secured

Overnight Financing Rate (‘SOFR’) for USD interest rates and BKBM for NZD interest rates. Ineffectiveness may arise from timing or discounting

differences on repricing between the hedged item and the derivative. For portfolio hedge accounting, ineffectiveness also arises from prepayment

risk (i.e. the difference between actual and expected prepayment of loans). In order to manage the ineffectiveness from early repayments and

accommodate new originations the portfolio hedges are de-designated and redesignated periodically.

Cash flow hedges

Interest rate risk

The Banking Group’s exposure to the volatility of interest cash flows from customer deposits and loans is hedged with interest rate derivatives

using a dynamic hedge accounting strategy called macro cash flow hedges. Customer deposits and loans are allocated to time buckets based on

their expected repricing dates. The interest rate derivatives are designated according to the gross asset or gross liability positions for the relevant

time buckets. The Banking Group hedges the benchmark interest rate which generally represents the most significant component of the changes

in fair value. The benchmark interest rate is a component of interest rate risk that is observable in the relevant financial markets, for example,

SOFR for USD interest rates and BKBM for NZD interest rates. Ineffectiveness may arise from timing or discounting differences on repricing

between the hedged item and the interest rate derivative. Ineffectiveness also arises if the notional values of the interest rate derivatives exceed

the aggregate notional exposure for the relevant time buckets. The hedge accounting relationship is reviewed on a monthly basis and the hedging

relationships are de-designated and redesignated if necessary.

FX risk

The Banking Group’s exposure to foreign currency principal and credit margin cash flows from fixed rate foreign currency debt issuances is

hedged through the use of cross currency derivatives in a one-to-one hedging relationship to manage the changes between the foreign currency

and NZD. In addition, for floating rate foreign currency debt issuances, the Banking Group hedges from foreign floating to NZD floating interest

rates. Ineffectiveness may arise from timing or discounting differences on repricing between the hedged item and the cross currency derivative.

Economic hedges

As part of the Banking Group’s ALM activities, economic hedges may be entered into to hedge long-term funding transactions for risk

management purposes. These hedges do not qualify for hedge accounting and are therefore not included in the hedging instrument disclosures

below.

Hedge effectiveness

Hedge effectiveness is tested prospectively at inception and during the lifetime of hedge relationships. For one-to-one hedge relationships this

testing uses a qualitative assessment of matched terms where the critical terms of the derivatives used as the hedging instrument match the

terms of the hedged item. In addition, a quantitative effectiveness test is performed for all hedges which could include regression analysis, dollar

offset and/or sensitivity analysis.

Retrospective testing is also performed to determine whether the hedge relationship remains highly effective so that hedge accounting can

continue to be applied and also to determine any ineffectiveness. These tests are performed using regression analysis and the dollar offset

method.

The following tables provide information regarding the determination of hedge effectiveness:

Note 24 Fair values of financial assets and financial liabilities
Accounting policy

The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction

between market participants at the measurement date.

On initial recognition, the transaction price generally represents the fair value of the financial instrument unless there is observable information

from an active market to the contrary. Where unobservable information is used, the difference between the transaction price and the fair value

(day one profit or loss) is recognised in the income statement over the life of the instrument or when the inputs become observable.

Critical accounting assumptions and estimates

The majority of valuation models used by the Banking Group employ only observable market data as inputs. However, for certain financial

instruments, data may be employed which is not readily observable in current markets.

The availability of observable inputs is influenced by factors such as:

●product type;

●depth of market activity;

●maturity of market models; and

●complexity of the transaction.

Where unobservable market data is used, more judgement is required to determine fair value. The significance of these judgements depends on

the significance of the unobservable input to the overall valuation. Unobservable inputs are generally derived from other relevant market data

and adjusted against:

●standard industry practice;

●economic models; and

●observed transaction prices.

In order to determine a reliable fair value for a financial instrument, management may apply adjustments to the techniques previously

described.

These adjustments reflect the Banking Group’s assessment of factors that market participants would consider in setting the fair value.

These adjustments incorporate bid/offer spreads, credit valuation adjustments and funding valuation adjustments.

Fair Valuation Control Framework

The Banking Group uses a Fair Valuation Control Framework where the fair value is either determined or validated by a function independent of the

transaction. This framework formalises the policies and procedures used to achieve compliance with relevant accounting, industry and regulatory

standards. The framework includes specific controls relating to:

●the revaluation of financial instruments;

●independent price verification;

●fair value adjustments; and

●financial reporting.

A key element of the framework is the Revaluation Committee, comprising senior valuation specialists from within the Ultimate Parent Bank Group.

The Revaluation Committee reviews the application of the agreed policies and procedures to assess that a fair value measurement basis has been

applied.

The method of determining fair value differs depending on the information available.

Fair value hierarchy

A financial instrument’s categorisation within the valuation hierarchy is based on the lowest level input that is significant to the fair value

measurement.

The Banking Group categorises all fair value instruments according to the hierarchy described below.

Valuation techniques

The Banking Group applies market accepted valuation techniques in determining the fair valuation of over-the-counter derivatives. This includes

credit valuation adjustments and funding valuation adjustments, which incorporate credit risk and funding costs and benefits that arise in relation

to uncollateralised derivative positions, respectively.

The specific valuation techniques, the observability of the inputs used in valuation models and the subsequent classification for each significant

product category are outlined as follows:

Level 2 instruments

The fair value for financial instruments that are not actively traded is determined using valuation techniques which maximise the use of observable

value on a recurring basis.

Analysis of movements between fair value hierarchy levels

For the year ended 30 September 2025, the Banking Group has refined its approach and applied a more granular assessment with additional

metrics sourced from its independent pricing services to complete the fair value level classification of New Zealand Government treasury bills. As

a result, $642 million of these trading securities and financial assets measured at FVIS have been transferred from Level 1 to Level 2. Transfers in

and transfers out are reported using the end of period fair values. There were no other material transfers between levels of the fair value hierarchy

during the year (30 September 2024: no material transfers between levels).

Financial instruments not measured at fair value

For financial instruments not measured at fair value on a recurring basis, fair value has been derived as follows:

InstrumentValuation

Loans

Where available, the fair value of loans is based on observable market transactions; otherwise fair value is

estimated using discounted cash flow models. For variable rate loans, the discount rate used is the current effective

interest rate. The discount rate applied for fixed rate loans reflects the market rate for the maturity of the loan and

the creditworthiness of the borrower.

Deposits and other

borrowings

Fair values of deposit liabilities payable on demand (interest free, interest bearing and savings deposits)

approximate their carrying value. Fair values for term deposits are estimated using discounted cash flows, applying

market rates offered for deposits of similar remaining maturities.

Due to related entities

The carrying value of due to related entities approximates the fair value. These items are either short-term in nature

or re-price frequently, and are of a high credit rating.

Debt issues and loan

capital

The fair values of these instruments are calculated based on quoted market prices, where available. Where quoted

market prices are not available, fair values are calculated using a discounted cashflow model. The discount rates

applied reflect the terms of the instruments and the timing of the estimated cash flows and are adjusted for any

changes in the Banking Group’s credit spreads.

All other financial

assets and financial

liabilities

For all other financial assets and financial liabilities, the carrying value approximates the fair value. These items are

either short-term in nature or re-price frequently, and are of a high credit rating.

Note 25 Offsetting financial assets and financial liabilities

Accounting policy

Financial assets and financial liabilities are presented net on the balance sheet when the Banking Group has a legally enforceable right to offset

them in all circumstances and there is an intention to settle the asset and liability on a net basis, or to realise the asset and settle the liability

simultaneously. The gross assets and liabilities behind the net amounts reported on the balance sheet are disclosed in the following table.

Notes to the financial statements

58Westpac New Zealand Limited

Note 25 Offsetting financial assets and financial liabilities (continued)
Some of the Banking Group’s offsetting arrangements are not enforceable in all circumstances. The amounts in the tables below may not tie back

to the balance sheet if there are balances which are not subject to offsetting or enforceable netting arrangements. The amounts presented in this

note do not represent the credit risk exposure of the Banking Group. Refer to Note 13 for information on credit risk management. The offsetting

and collateral arrangements and other credit risk mitigation strategies used by the Banking Group are further explained in the ‘Management of risk

These financial assets and financial liabilities are subject to master netting agreements which are not enforceable in all circumstances, so they are

recognised gross on the balance sheet. The offsetting rights of the master netting arrangements can only be enforced if a predetermined event

occurs in the future, such as a counterparty defaulting.

Cash collateral and financial instrument collateral

These amounts are received or pledged under master netting arrangements against the gross amounts of assets and liabilities. Financial

instrument collateral typically comprises securities which can be readily liquidated in the event of counterparty default. The offsetting rights of the

master netting arrangement can only be enforced if a predetermined event occurs in the future, such as a counterparty defaulting.

Note 26 Credit related commitments, contingent assets and contingent liabilities
Accounting policy

Undrawn credit commitments

The Banking Group enters into various arrangements with customers which are only recognised on the balance sheet when called upon.

These arrangements include commitments to extend credit, bill endorsements, financial guarantees, standby letters of credit and underwriting

facilities.

Contingent assets

Contingent assets are possible assets whose existence will be confirmed only by uncertain future events. Contingent assets are not recognised

on the balance sheet but are disclosed if an inflow of economic benefits is probable.

Contingent liabilities

Contingent liabilities are possible obligations whose existence will be confirmed only by uncertain future events, and present obligations where

the transfer of economic resources is not probable or cannot be reliably measured. Contingent liabilities are not recognised on the balance

sheet but are disclosed unless the outflow of economic resources is remote.

Undrawn credit commitments

Undrawn credit commitments expose the Banking Group to liquidity risk when called upon and also to credit risk if the customer fails to repay the

amounts owed at the due date. The maximum exposure to credit loss is the contractual or notional amount of the instruments disclosed below.

Some of the arrangements can be cancelled by the Banking Group at any time. The actual liquidity and credit risk exposure varies in line with

drawings and may be less than the amounts disclosed. The Banking Group uses the same credit policies when entering into these arrangements as

it does for on-balance sheet instruments. Refer to Note 13 and Note 31 for further details on credit risk management and liquidity risk.

Letters of credit and guarantees includes the value of exposures guaranteed by the Bank to NZ Branch, as disclosed in Note 22 Related entities.

3

Commitments to extend credit include all obligations on the part of the Banking Group to provide credit facilities. As facilities may expire without being drawn

upon, the notional amounts do not necessarily reflect future cash requirements.

4

In addition to the commitments disclosed above, there is $1,478 million (30 September 2024: $1,014 million) of exposure to credit risk primarily relating to credit

exposures offered and accepted but still revocable, which represent part of the Banking Group's maximum exposure to credit risk.

5

Comparatives have been revised to remove credit exposures offered and accepted but still revocable.

Contingent assets

The Banking Group enters into various arrangements with customers that constitute contingent assets. If a specified contingent event occurs,

these commitments will be called upon and recognised on the balance sheet as loans.

Contingent liabilities

The Banking Group has contingent risks and liabilities arising from the conduct of its business, including: actual and potential disputes, claims,

legal proceedings, investigations, inquiries and reviews (formal and informal) carried out by regulatory authorities (including into the Banking

Group's processes for some products relating to the requirements of the CCCFA); and internal investigations and reviews.

The scope of reviews (internal and external), investigations and inquiries, including those relating to the requirements of the CCCFA, can be wide-

ranging and can result in litigation (including class action proceedings and enforcement proceedings), fines and penalties, customer remediation

and/or other sanctions and reputational damage.

All potential claims and other liabilities are assessed on a case-by-case basis. A provision will be recognised where the Banking Group has

conducted an assessment which determines the likelihood of loss as probable and where its potential loss can be reliably estimated. A contingent

liability exists in respect of actual or potential claims where the likely loss is not assessed as probable, where the law is uncertain or, in rare

circumstances, where the outflow of resources cannot be reliably estimated.

Guarantees

As disclosed in Note 22, the Bank has an agreement with the NZ Branch whereby the Bank will reimburse the NZ Branch for any credit losses

incurred by it due to certain customers of the Bank defaulting on certain financial market and international products.

Note 27 Segment reporting
Accounting policy

Operating segments are presented on a basis that is consistent with information provided internally to the Banking Group’s chief operating

decision-maker and reflect the management of the business, rather than the legal structure of the Banking Group. The chief operating decision-

maker is the person or group that allocates resources to and assesses the performance of the operating segments of an entity. The Banking

Group has determined that the Bank’s executive team is its chief operating decision-maker.

Inter-segment revenue and costs are eliminated at head office. Income and expenses directly associated with each segment are included in

determining business segment performance.

The Banking Group’s segment reporting incorporates Consumer Banking and Wealth and Institutional and Business Banking sectors within New

Zealand. On this basis, no geographical segment reporting is provided.

The operating segment results have been presented on a management reporting basis and consequently internal charges and transfer pricing

adjustments have been reflected in the performance of each operating segment. Intersegment pricing is determined on a cost recovery basis.

The Banking Group does not rely on any single major customer for its revenue base.

Segment comparative information for the year ended 30 September 2024 has been revised to align to the current year's basis for reporting, and is

consistent with the information provided internally to the Banking Group's chief operating decision-maker.

The Banking Group’s operating segments are defined by the customers they serve and the services they provide. The Banking Group has identified

the following main operating segments:

●Consumer Banking and Wealth provides financial services predominantly for individuals; and

●Institutional and Business Banking provides a broad range of financial services for small to medium enterprise, corporate, property finance,

agricultural, institutional and government customers.

Other primarily represents:

●business units that do not meet the definition of a reportable operating segment under NZ IFRS 8 Operating Segments;

●elimination entries on consolidation of the results, assets and liabilities of the Banking Group’s controlled entities in the preparation of the

consolidated financial statements of the Banking Group; and

●results of certain business units excluded for management reporting purposes, but included within the consolidated financial statements of

the Banking Group for statutory financial reporting purposes.

Note 28 Securitisation, covered bonds and other transferred assets
The Banking Group enters into transactions in the normal course of business by which financial assets, or an interest in such assets or cashflows

arising from such assets, are transferred to counterparties or structured entities. Depending on the circumstances, these transfers may result in

derecognition of the assets in their entirety, partial derecognition or no derecognition of the asset. For the Banking Group’s accounting policy on

derecognition of financial assets, refer to Note 1.

Securitisation

Securitisation is the process of selling a group of assets (or an interest in the assets or the cashflow arising from the assets) to a special purpose

entity which then issues interest bearing debt securities for funding and liquidity purposes.

Securitisation of its own assets is used by the Banking Group as a funding and liquidity tool.

In October 2008, the Banking Group set up WNZSL as a structured entity for the purpose of structuring assets that are eligible for repurchase

agreements with the Reserve Bank as part of the Bank’s internal residential mortgage-backed securitisation programme.

Under the internal residential mortgage-backed securitisation programme, the Bank periodically sells the rights (but not the obligations) under

eligible housing loans to WNZSL. The purchase by WNZSL of the housing loans is funded by the proceeds of the issuance of RMBS.

The Bank is obliged to repurchase any housing loan sold to and held by WNZSL where the housing loan does not meet the eligibility criteria of the

programme. It is not envisaged that any liability resulting in material loss to the Banking Group will arise from these obligations.

Covered bonds

The Banking Group has a covered bond programme under which it may issue bonds (Covered Bonds). From time to time, the Banking Group

transfers, via assignment, housing loans originated by the Bank to a bankruptcy remote structured entity, WNZCBL. WNZCBL is a special purpose

entity which holds the rights to, but not the obligations under, the pool of housing loans held by it (the Portfolio). The payments of all amounts due

in respect of the Covered Bonds have been unconditionally guaranteed by the Bank. In addition, WNZCBL (the CB Guarantor) has guaranteed

payments of interest and principal under the Covered Bonds pursuant to a financial guarantee which is secured by WNZCBL granting security over

the Portfolio and its other assets. Recourse against the CB Guarantor under its guarantee is limited to the Portfolio and such assets.

The intercompany loan made by the Bank to WNZCBL to fund the initial and all subsequent purchases of eligible housing loans and the liability

representing the intercompany loan from WNZCBL to the Bank are fully eliminated in the Banking Group’s financial statements.

The Banking Group is obliged to repurchase any housing loans sold to and held by WNZCBL (pursuant to the Bank’s Global Covered Bond

Programme) in certain circumstances including (but not limited to) where:

●it is discovered that there has been a material breach of a sale warranty (or any such sale warranty is materially untrue);

●the loan becomes materially impaired or is enforced prior to the second monthly covered bond payment date falling after the assignment of

the loan; or

●at the cut-off date relating to the loan, there were arrears of interest and that loan subsequently becomes a delinquent loan prior to the

second monthly covered bond payment date falling after the assignment of the loan.

It is not envisaged that any liability resulting in material loss to the Banking Group will arise from these obligations.

Repurchase agreements

Where securities are sold subject to an agreement to repurchase at a predetermined price, they remain recognised on the balance sheet in their

original category (i.e. trading securities and financial assets measured at FVIS or investment securities). Repurchase agreements are designated at

fair value when they are managed as part of a trading portfolio, otherwise they are measured on an amortised cost basis.

The cash consideration received is recognised as a liability (repurchase agreements). Refer to Note 17 for further details

The most senior rated securities at 30 September 2025 of $10,670 million (30 September 2024: $13,800 million) qualify as eligible collateral for repurchase

agreements with the Reserve Bank. The Bank complies with the Reserve Bank’s guidelines for its overnight reverse repurchase agreement facility and open market

operations, which allows banks in New Zealand to offer RMBS as collateral for the Reserve Bank’s repurchase agreements.

2

The difference between the carrying values of the covered bonds and the assets pledged allows for the immediate issuance of additional covered bonds if required.

These additional assets can be repurchased by the Bank at its discretion, subject to the conditions set out in the transaction documents. The Portfolio is comprised

of housing loans up to a value of $7,500 million as at 30 September 2025 (30 September 2024: $7,500 million). Over time, the composition of the Portfolio will

include, in addition to housing loans, accrued interest (representing accrued and unpaid interest on the outstanding housing loans) and cash (representing

collections of principal and interest from the underlying housing loans).

Note 29 Structured entities

Accounting policy

Structured entities are generally created to achieve a specific, defined objective and their operations are restricted such as to only purchasing

specific assets. Structured entities are commonly financed by debt or equity securities that are collateralised by and/or indexed to their

underlying assets. The debt and equity securities issued by structured entities may include tranches with varying levels of subordination.

Structured entities are classified as subsidiaries and consolidated if they meet the definition in Note 1. If the Banking Group does not control a

structured entity then it will not be consolidated.

The Banking Group engages in various transactions with both consolidated and unconsolidated structured entities that are mainly involved in

securitisations, asset backed structures and managed funds.

Consolidated structured entities

Securitisation and covered bonds

The Banking Group uses structured entities to securitise its financial assets through the Covered Bond Programme and the Bank’s internal

residential mortgage-backed securitisation programme. Refer to Note 28 for further details.

Funds managed by a member of the Ultimate Parent Bank Group

As disclosed in Note 22, the PIE Funds are consolidated within the financial statements of the Banking Group.

Non-contractual financial support

The Banking Group does not provide non-contractual financial support to these consolidated structured entities.

Unconsolidated structured entities

The Banking Group has interests in various unconsolidated structured entities including debt instruments, liquidity arrangements, lending, loan

commitments and certain derivatives.

Interests exclude non-complex derivatives (e.g. interest rate swap agreements) and lending to a structured entity with recourse to a wider

operating entity, not just the structured entity.

The Banking Group’s main interests in unconsolidated structured entities, which arise in the normal course of business, are loans and other credit

commitments. The Banking Group lends to unconsolidated structured entities, subject to the Banking Group’s collateral and credit approval

processes, in order to earn interest and fees and commissions income. The structured entities are mainly securitisation entities.

Notes to the financial statements

Westpac New Zealand Limited63

Note 29 Structured entities (continued)
The following table shows the Banking Group’s interests in unconsolidated structured entities and its maximum exposure to loss in relation to

those interests. The maximum exposure does not take into account any collateral or hedges that will reduce the risk of loss.

●For on-balance sheet instruments, including debt instruments in and loans to unconsolidated structured entities, the maximum exposure to

loss is the carrying value; and

●For off-balance sheet instruments, including liquidity facilities and loan and other credit commitments, the maximum exposure to loss is the

notional amounts.

Note 30 Capital management

The primary objectives of the Banking Group’s capital management activities are to ensure that the Banking Group complies with the regulatory

capital requirements prescribed by the Reserve Bank, maintains strong credit ratings and a strong capital position to support its business

objectives and maximises shareholder value.

The Banking Group manages and adjusts its capital structure in light of changing economic conditions and the risk characteristics of its activities.

To maintain or adjust the capital structure, the Banking Group may adjust the amount of dividend payments to its shareholders, reduce

discretionary expenditure, return or issue capital to its shareholders or issue capital securities.

Three independent processes, undertaken by Directors and senior management of the Bank, are designed to manage the Banking Group’s capital

adequacy to support its current and future activities:

1.The Banking Group actively monitors its capital adequacy as part of the annual Banking Group ICAAP and reports this to senior management

and the Bank’s Board. This process supports the Board approved risk appetite statement which outlines the target capital ratios. The Bank

sets its target capital ratios at a higher level than required by the regulator, which reduces the risk of breaching the conditions of

registration.

2.The Banking Group calculates the capital required to be held for its current risk profile and forecasts the estimated capital position based on

expected future activities. The forecast capital required is assessed against the target ranges that have been approved by the Board in

regard to capital ratios. The Banking Group also reviews its capital positions in this process against other stakeholder requirements to

ensure capital efficiency.

3.The Ultimate Parent Bank Group takes capital considerations into account during its Board Strategy Review, which is an annual process

where the current strategic direction of the Ultimate Parent Bank Group is reviewed and refined.

Reserve Bank Capital Reviews

On 5 December 2019, the Reserve Bank announced changes to the capital adequacy framework that applies to New Zealand incorporated

registered banks (including the Bank) requiring:

●Progressively increasing the total capital requirements to 18% of RWAs for domestic systemically important banks (including the Bank) and

16% for all other banks over a seven-year period ending 1 July 2028, including:

-Increasing the Tier 1 capital requirement from 8.5% to 16% of RWAs for domestic systemically important banks;

-Increasing the AT1 limit from 1.5% to 2.5% of the Tier 1 capital requirement; and

-Maintaining the existing Tier 2 capital limit of 2% of the total capital requirement.

These ratios include the minimum capital ratios that banks must maintain and the prudential capital buffer above the minimum capital

ratios that banks must maintain to avoid restrictions on distributions (among other things).

●Eligible Tier 1 capital under the new framework comprises common equity and redeemable PPS. Existing, non-qualifying AT1 instruments are

being progressively phased out by 1 July 2028;

The increases in the required level of bank capital started to come into effect on 1 July 2022 and are scheduled to be fully implemented on 1 July

2028. The prudential capital buffer increased from 4.5% to 5.5% on 1 July 2025.

However, on 31 March 2025, the Reserve Bank announced that it would conduct a review of the key capital settings for deposit takers (including

the Bank) with a consultation paper released on 25 August 2025. Refer to page 82 for more information.

31.1 Risk management frameworks

The Board is responsible for approving the Banking Group’s Risk Appetite Statement and, through the BRCC, the Risk Management Framework and

the Risk Management Strategy. The Board is also responsible for monitoring the effectiveness of risk management by the Banking Group. The

Banking Group is wholly owned by the Ultimate Parent Bank and, therefore, a member of the group of companies comprising the Ultimate Parent

Bank Group. Accordingly, the Banking Group’s Risk Management Framework is closely aligned with the Ultimate Parent Bank’s Risk Management

Framework.

The Board has delegated authority to the BRCC to:

●review and recommend the Banking Group’s Risk Appetite Statement to the Board for approval;

●approve the Banking Group’s Risk Management Framework and Risk Management Strategy;

●review and monitor the risk profile and controls of the Banking Group consistent with the Banking Group’s Risk Appetite Statement; and

●approve certain frameworks, policies and processes for managing risk (consistent with the Banking Group’s Risk Management Framework,

Risk Management Strategy and Risk Appetite Statement).

For each of its primary financial risks, the Banking Group maintains risk management frameworks and a number of supporting policies that define

roles and responsibilities, acceptable practices, limits and key controls.

the oversight of the Banking Group’s ALCO and the Financial

Markets and Treasury Risk unit.

-The Banking Group’s Liquidity Risk Management Framework

sets out the Banking Group’s funding and liquidity risk

appetite, roles and responsibilities of key people managing

funding and liquidity risk within the Banking Group, risk

reporting and control processes and limits and targets used

to manage the Banking Group’s balance sheet.

-Treasury undertakes an annual funding review that outlines

the Banking Group's balance sheet funding strategy over a

three year period. This review encompasses trends in global

markets, peer analysis, wholesale funding capacity,

expected funding requirements and a funding risk analysis.

This strategy is continuously reviewed to take account of

changing market conditions, investor sentiment and

estimations of asset and liability growth rates. This review is

subsequently submitted to the BRCC for approval.

-The Banking Group monitors the composition and stability

of its funding to allow it to remain within the Banking

Group’s funding risk appetite and comply with regulatory

requirements.

-The Banking Group holds a portfolio of liquid assets for

several purposes, including as a buffer against unforeseen

funding requirements. The level of liquid assets held takes

into account the liquidity requirements of the Banking

Group's balance sheet under normal and stress conditions.

-Treasury also maintains a contingent funding plan that

outlines the steps that should be taken by the Banking

Group in the event of an emerging ‘funding crisis’. The plan

is aligned with the Banking Group’s broader Liquidity Crisis

Management Policy which is approved by the BRCC.

-Daily liquidity risk reports are reviewed by Treasury and the

Financial Markets and Treasury Risk unit. Liquidity reports

are presented to ALCO monthly and to the RISKCO and

BRCC quarterly.

Notes to the financial statements

Westpac New Zealand Limited67

Note 31 Risk management, funding and liquidity risk and market risk (continued)
Climate change risk

The Banking Group recognises climate change as a major threat to our collective wellbeing and is committed to transparency and action across its

business to address climate change. While this is not a material financial risk as at 30 September 2025 (30 September 2024: not a material

financial risk), climate change risk is evolving and is expected to have a more significant impact on the Banking Group’s material financial risks in

the future.

The two main sources of financial risks arising from climate change are physical risks and transition risks. Physical risks emanating from climate

change can be event-driven (acute) such as increased severity and frequency of extreme weather events (e.g., cyclones, droughts, floods, and

fires). They can also relate to longer-term shifts (chronic) in precipitation and temperature and increased variability in weather patterns or other

long-term changes such as sea level rise. Transition risks are risks associated with the transition to a lower-carbon global economy, the most

common of which relate to policy and legal actions, technology changes, market responses, and reputational considerations.

The Banking Group seeks to understand the potential for climate-related transition and physical risks to impact its business, including their

possible impact on credit risk, regulatory and reporting obligations, and our reputation.

In December 2022, the XRB published climate standards (‘XRB climate standards’) for mandatory climate-related disclosures, taking effect for

accounting periods commencing from 1 January 2023. The XRB climate standards establish disclosure requirements for climate reporting entities,

including large registered banks, and are aligned to the recommendations of the Task Force on Climate-related Financial Disclosures. The Bank is

a climate reporting entity. Its second XRB climate standards-compliant report for the year ended 30 September 2025 is scheduled to be published

on or before 31 January 2026, and will be available on the Bank's website (www.westpac.co.nz/about-us/legal-information-privacy/disclosure-

statements/).

The Banking Group has considered the impact of climate-related risks on its financial position and performance and while the effects of climate

change represent a source of uncertainty, the Banking Group has concluded that climate-related risks do not have a material impact on the

judgements, assumptions and estimates for the year ended 30 September 2025 (30 September 2024: no material impact). Refer to Note 13.1 for

further information on how climate change risk is considered as part of credit risk.

31.2 Funding and liquidity risk

The Banking Group aims to maintain a mix of retail and wholesale funding, with emphasis on the value of core funding consistent with the

principles inherent in BS13.

31.2.1 Liquidity modelling

The Banking Group is subject to the conditions of BS13. The following metrics are calculated and reported on a daily basis in accordance with BS13:

●the level of liquid assets held;

●the one-week mismatch ratio;

●the one-month mismatch ratio; and

●the one-year core funding ratio.

In addition, the Banking Group calculates the following liquidity ratios in accordance with the Ultimate Parent Bank’s liquidity risk framework under

APRA Prudential Standard APS 210 Liquidity:

●liquidity coverage ratio; and

●net stable funding ratio.

Notes to the financial statements

Note 31 Risk management, funding and liquidity risk and market risk (continued)
31.2.2 Sources of funding

Sources of funding are regularly reviewed to maintain a wide diversification by currency, geography, product and term. Sources include, but are

not limited to:

●deposits;

●debt issues;

●loan capital;

●proceeds from sale of marketable securities;

●repurchase agreements with central banks;

●related entities;

●principal repayments on loans;

●interest income; and

●fees and commissions income.

Term Lending Facility and Funding for Lending Programme

From 26 May 2020 until the extended date of 28 July 2021, the Reserve Bank made available a Term Lending Facility (‘TLF’), to offer loans for a

maximum term of five years at the rate of the Official Cash Rate, with access to the funds linked to banks’ lending under the TLF Scheme. As at 30

September 2025, the Banking Group has a balance of $24 million under the TLF (30 September 2024: $42 million).

On 11 November 2020, the Reserve Bank announced that additional stimulus would be provided through a Funding for Lending Programme (‘FLP’),

commencing in December 2020. The FLP provides funding to banks at the prevailing OCR for a term of three years, secured by high quality

collateral. The size of funding available under the FLP includes an initial allocation of 4% of each bank’s eligible loans (as defined by the Reserve

Bank). A conditional additional allocation of up to 2% of eligible loans is also available, subject to growth in eligible loans, for a total size of up to

6% of eligible loans. The FLP ran from 7 December 2020 to 6 June 2022 for the initial allocations and ended on 6 December 2022 for the additional

allocations. The FLP term sheet is available on the Reserve Bank’s website. As at 30 September 2025, the Banking Group has a balance of $1,110

million under the FLP (30 September 2024: $2,981 million).

Liquid assets

The following table shows the Banking Group’s qualifying liquid assets held for the purpose of managing liquidity risk. These assets are eligible for

repurchase agreements with the Reserve Bank and are held in cash, government, local government and highly rated investment grade securities.

The level of liquid asset holdings is reviewed frequently and is consistent with regulatory, balance sheet and market condition requirements.

As at 30 September 2025, the Banking Group has undertaken repurchase agreements with the Reserve Bank, under the FLP and TLF, using RMBS. For the FLP, the

repurchase cash amount as at 30 September 2025 is $1,110 million (30 September 2024: $2,981 million), which is recorded within other financial liabilities on the

balance sheet, with underlying securities to the value of $1,503 million provided under the arrangement (30 September 2024: $3,989 million). For the TLF, the

repurchase cash amount at 30 September 2025 is $24 million (30 September 2024: $42 million), which is recorded within other financial liabilities on the balance

sheet, with underlying securities to the value of $29 million provided under the arrangement (30 September 2024: $50 million).

31.2.4 Contractual maturity of financial liabilities

The following table presents cash flows associated with financial liabilities, payable at the balance sheet date, by remaining contractual maturity.

The amounts disclosed in the table are the future contractual undiscounted cash flows, whereas the Banking Group manages inherent liquidity risk

based on expected cash flows.

Cash flows associated with these financial liabilities include both principal payments as well as fixed or variable interest payments incorporated

into the relevant coupon period. Principal payments reflect the earliest contractual maturity date. Derivative financial instruments designated in

hedge accounting relationships and used as economic hedges are expected to be held for their remaining contractual lives, and reflect gross cash

flows over the remaining contractual term.

Trading derivatives that are considered economic hedges are included as ‘held for hedging purposes’ in the following table. Derivatives held for

trading, which excludes economic hedges, and certain liabilities classified in “Other financial liabilities” which are measured at FVIS are not

managed for liquidity purposes on the basis of their contractual maturity, and accordingly these liabilities are presented in the up to 1 month

column. Only the liabilities that the Banking Group manages based on their contractual maturity are presented on a contractual undiscounted

basis in the following table.

31.2.5 Expected maturity

The following table presents the balance sheet based on expected maturity dates. The liability balances in the following table will not agree to the

contractual maturity tables due to the analysis below being based on expected rather than contractual maturities, the impact of discounting and

the exclusion of interest accruals beyond the reporting period. Deposits are presented in the following table on a contractual basis, however as

part of our normal banking operations, the Banking Group expects a large proportion of these balances to be retained.

31.3 Market risk

31.3.1 VaR

The Banking Group uses VaR as one of the mechanisms for controlling non-traded market risk.

VaR is a statistical estimate of the potential loss in earnings over a specified period of time and to a given level of confidence based on historical

market movements. The confidence level indicates the probability that the loss will not exceed the VaR estimate on any given day.

VaR seeks to take account of all material market variables that may cause a change in the value of the portfolio, including interest rates, FX rates,

price changes, volatility and the correlations between these variables. Daily monitoring of current exposures and VaR and structural limit

utilisation is conducted independently by the Financial Markets and Treasury Risk unit.

Daily stress testing and back testing of VaR results are performed to support model integrity and to analyse extreme or unexpected movements. A

review of the potential profit and loss outcomes is also undertaken to monitor any skew created by the historical data.

The key parameters of VaR are:

Holding period1 day

Confidence level99%

Period of historical data used1 year

31.3.2 Non-traded market risk

Non-traded market risk includes IRRBB – the risk to interest income from a mismatch between the duration of assets and liabilities that arises in

the normal course of business activities.

NII sensitivity is monitored in terms of the NaR. A simulation model is used to calculate the Banking Group’s potential NaR. This combines the

underlying balance sheet data with assumptions about runoffs and new business, expected repricing behaviour and changes in wholesale market

interest rates.

Net interest income-at-Risk

The following table depicts potential NII outcomes assuming a worst case 100 basis point rate shock (up and down) with a 12 month time horizon

IRRBB VaR includes interest rate risk and other basis risks used for internal management purposes.

Risk mitigation

IRRBB stems from the ordinary course of banking activities, including structural interest rate risk (the mismatch between the duration of assets

and liabilities) and capital management.

The Banking Group hedges its exposure to such interest rate risk using derivatives. Further details on the Banking Group’s use of hedge accounting

are discussed in Note 23.

This section contains the additional disclosures required by the Order.
i. General information (Unaudited)

Ultimate Parent Bank

The Ultimate Parent Bank is incorporated in Australia under the Australian Corporations Act 2001 and its address for service of process is Level 18,

Westpac Place, 275 Kent Street, Sydney, New South Wales 2000, Australia.

Limits on material financial support by the Ultimate Parent Bank

The Ultimate Parent Bank is an ADI under the Banking Act 1959 (Commonwealth of Australia) (‘Australian Banking Act’) and, as such, is subject

to prudential regulation and supervision by APRA. APRA has the power to prescribe prudential requirements which may affect the ability of the

Ultimate Parent Bank to provide material financial support to the Bank. Pursuant to current APRA requirements, and unless APRA provides

otherwise, the Ultimate Parent Bank must comply with, among other prudential requirements, APS 222.

APS 222 includes the following prudential requirements:

●the Ultimate Parent Bank’s exposure to the Bank (being an overseas equivalent of an ADI as defined in APS 222) must not exceed 25% of the

Ultimate Parent Bank’s Level 1 capital base (as defined in APS 222);

●the Ultimate Parent Bank must not hold unlimited exposures to the Bank;

●the Ultimate Parent Bank must not enter into cross-default provisions whereby a default by the Bank on an obligation (whether financial or

otherwise) triggers or is deemed to trigger a default of the Ultimate Parent Bank in its obligations; and

●when determining limits on acceptable levels of exposure to the Bank, the Ultimate Parent Bank must have regard to:

-the level of exposures that would be approved for unrelated entities of broadly equivalent credit status; and

-the impact on the Ultimate Parent Bank’s stand-alone capital and liquidity positions in the event of a failure of the Bank or any other

related entity to which it is exposed.

Under APS 222, APRA has the ability to set specific limits on the Ultimate Parent Bank’s exposure to related entities, which include the Bank.

The Ultimate Parent Bank complies with the requirements set by APRA in respect of the extent of financial support that is provided to the Bank.

Section 13A(3) of the Australian Banking Act provides that if an ADI becomes unable to meet its obligations or suspends payment, the assets of the

ADI in Australia are to be available to satisfy the liabilities of the ADI in the following order:

●first, certain obligations of the ADI to APRA (if any) arising under Division 2AA of Part II of the Australian Banking Act in respect of amounts

payable by APRA to holders of 'protected accounts' (as defined in Australian Banking Act) as part of the Financial Claims Scheme for the

Australian Government guarantee of ‘protected accounts’ (including most deposits) up to A$250,000 per account holder in the winding-up

of the ADI;

●second, APRA's costs (if any) in exercising its powers and performing its functions relating to the ADI in connection with the Financial Claims

Scheme;

●third, the ADI’s liabilities (if any) in Australia in relation to ‘protected accounts’ that account-holders keep with the ADI; ‘Protected accounts’

do not include accounts kept at a foreign branch of an ADI;

●fourth, the ADI’s debts (if any) to the Reserve Bank of Australia;

●fifth, the ADI’s liabilities (if any) under an emergency financial ‘industry support contract’ that is certified by APRA in accordance with the

Australian Banking Act; and

●sixth, the ADI’s other liabilities (if any) in the order of their priority apart from the above.

Under section 16 of the Australian Banking Act, on the winding-up of an ADI, APRA's cost of being in control of an ADI’s business, or having an

administrator in control of an ADI’s business, is a debt due to APRA. Debts due to APRA shall have, subject to section 13A(3) of the Australian

Banking Act, priority over all other unsecured debts of that ADI.

APRA requires that the ELE of the Ultimate Parent Bank limit its non-equity exposures to New Zealand banking subsidiaries to 5% of the Ultimate

Parent Bank’s Level 1 Tier 1 capital, as part of an initiative to reduce Australian bank non-equity exposure to their respective New Zealand banking

subsidiaries.

The ELE consists of the Ultimate Parent Bank and its subsidiary entities that have been approved by APRA to be included in the ELE for the

purposes of measuring capital adequacy. New Zealand banking subsidiaries include the Bank and any of its subsidiaries.

Exposures for the purposes of this limit include all committed, non-intraday, non-equity exposures including derivatives and off-balance sheet

exposures. For the purposes of assessing this exposure, the 5% limit excludes equity investments and holdings of capital instruments in New

Zealand banking subsidiaries.

While the limit and associated conditions do not apply to the ELE's non-equity exposures to the NZ Branch (which is within the ELE), the limit and

associated conditions do apply to the NZ Branch's non-equity exposures to New Zealand banking subsidiaries. As at 30 September 2025, the ELE’s

non-equity exposures to New Zealand banking subsidiaries affected by the limit were below 5% of Level 1 Tier 1 capital of the Ultimate Parent Bank.

APRA has also confirmed the terms on which the Ultimate Parent Bank ‘may provide contingent funding support to a New Zealand banking

subsidiary during times of financial stress’. APRA has confirmed that, at this time, only covered bonds meet its criteria for contingent funding

arrangements.

Westpac New Zealand Limited77

i. General information (Unaudited) (continued)
Voting securities and power to appoint directors

The Bank is a wholly-owned subsidiary of Westpac New Zealand Group Limited, a New Zealand incorporated company, which is a wholly-owned

subsidiary of Westpac Overseas Holdings No. 2 Pty Limited, an Australian incorporated company. Westpac Overseas Holdings No. 2 Pty Limited is,

in turn, a wholly-owned subsidiary of the Ultimate Parent Bank.

At 30 September 2025, Westpac New Zealand Group Limited has a direct qualifying interest in 100% of the voting securities of the Bank. Westpac

Overseas Holdings No. 2 Pty Limited and the Ultimate Parent Bank have an indirect qualifying interest in 100% of the voting securities of the Bank.

The Ultimate Parent Bank has the power under the Bank’s constitution to directly appoint up to 100% of the Board from time to time by giving

written notice to the Bank.

Priority of financial liabilities in the event of liquidation

In the unlikely event that the Bank was put into liquidation or ceased to trade, claims of secured creditors and those classes of creditors set out in

Schedule 7 of the Companies Act 1993 would rank ahead of the claims of unsecured creditors in accordance with the priorities set out in that

Schedule. Deposits from customers are unsecured and rank equally with other unsecured unsubordinated liabilities of the Bank, and such

liabilities would rank ahead of any subordinated instruments issued by the Bank to the extent of any such subordination.

Guarantee arrangements

No material obligations of the Bank are guaranteed as at the date the Directors signed this Disclosure Statement.

The Bank’s Conflicts of Interest Policy establishes procedures to ensure that conflicts and potential conflicts of interest between the Directors’

duty to the Bank and their personal, professional or business interests are managed appropriately.

Each Director must give notice to the Board of any direct or indirect interest in a matter relating to the affairs of the Bank as soon as practicable

after the relevant facts have come to that Director’s knowledge. Where a matter is to be considered at a Directors’ meeting in which one or more

Directors have an interest, the Board's practice is to manage any conflict of interest on a case-by-case basis, depending on the circumstances.

Transactions with directors

There is no transaction any Director, or any immediate relative or close business associate of any Director, has with any member of the Banking

Group, that:

●Has been entered into on terms other than those which would, in the ordinary course of business of the Banking Group, be given to any

other person of like circumstances or means; or

●Could otherwise be reasonably likely to influence materially the exercise of that Director’s duties.

Information pertaining to loans to and other transactions with Directors is disclosed in Note 22 of this Disclosure Statement.

Other material matters

Reserve Bank review of overseas bank branches

On 21 August 2024, the Reserve Bank released the proposed Branch Standard under the Deposit Takers Act 2023. The proposed Branch Standard

will require that overseas bank branches only conduct business with wholesale clients; the total size of an overseas bank's branch cannot exceed

NZ$15 billion in total assets; and dual-operating branches (such as the NZ Branch) only conduct business with “large corporate and institutional

clients" (LCIC).

Policy decisions released by the Reserve Bank on 17 July 2025 propose that LCIC means those with consolidated annual turnover of over NZ$50

million, total assets of over NZ$75 million or total assets under management of over NZ$250 million (for funds management entities only). The

implementation date is expected to be 1 December 2028.

The NZ Branch currently provides financial markets, trade finance and international payment products and services to customers referred by the

Bank. We expect the Reserve Bank’s Branch Standard will require changes to the activities the NZ Branch undertakes and as a result, the Bank may

also make changes to the scope of the activities it undertakes.

Reserve Bank review of capital settings for deposit takers

On 31 March 2025, the Reserve Bank announced a review of the key capital settings for deposit takers. On 25 August 2025, it released a

consultation paper. For Group 1 deposit takers (including the Bank) the key proposals include:

●Removal of AT1 instruments from the capital stack.

●Two options for capital ratio requirements:

oOption 1: A total Common Equity Tier 1 (CET1) capital ratio requirement of 14%, with a total capital ratio requirement of 17% (including

a prudential capital buffer (PCB) ratio of 8%).

oOption 2: A total CET1 capital ratio requirement of 12%, with a total capital ratio requirement of 15% (including a PCB ratio of 6%) and

an additional Loss Absorbing Capacity (LAC) requirement of 6%. Tier 2 capital and LAC instruments would be required to be issued

internally (for example to the Ultimate Parent Bank) and LAC would take a form similar to Tier 2 capital.

●More granular standardised risk weights, including lower risk weights in some areas.

●Setting the long-run level for the counter-cyclical capital buffer component of the PCB at 1%.

The Reserve Bank is expected to make its final decisions in December 2025, with the implementation timeline to be announced in the first quarter

of the 2026 calendar year. The outcome of the review remains uncertain.

Depositor Compensation Scheme

The Depositor Compensation Scheme (DCS) took effect from 1 July 2025. If a licensed deposit taker (including the Bank) fails, the DCS will protect

eligible depositors with money held in DCS-protected accounts up to $100,000 per depositor, per deposit taker. Most transaction, savings, notice,

term deposit and PIE accounts are protected accounts. The DCS is administered by the Reserve Bank. For more information about the scheme,

please refer to the Reserve Bank's website.

ii. Additional financial disclosures (continued)
Additional information on interest rate sensitivity

Sensitivity to interest rates arises from mismatches in the interest rate characteristics of assets and the corresponding liability funding. One of the

major causes of these mismatches is timing differences in the repricing of assets and liabilities. These mismatches are actively managed as part of

the overall interest rate risk management process, which is conducted in accordance with the Banking Group’s policy guidelines.

The following table presents a breakdown of the earlier of the contractual repricing or maturity dates of the Banking Group’s net asset position as

at 30 September 2025. The Banking Group uses this contractual repricing information as a base, which is then altered to take account of customer

behaviour, to manage its interest rate risk.

Additional mortgage information

Residential mortgages by LVR as at 30 September 2025

LVRs are calculated as the current exposure divided by the Banking Group’s valuation of the associated residential property at origination.

The Banking Group utilises data from its loan system to obtain origination valuations. For loans originated prior to 1 January 2008, or those

originated outside of the loan system, the origination valuation is not recorded in the system and is therefore, due to system limitations, not

available for disclosure. For these loans, the Banking Group utilises the earliest valuation recorded as the closest available alternative to estimate

an origination valuation.

Exposures for which no LVR is available have been included in the ‘Exceeds 90%’ category in accordance with the requirements of the Order.

credit risk mitigation from credit derivatives as at 30 September 2025.

Impact of the Standardised Floor on Total Credit Risk RWAs

BPR130 Credit risk RWAs overview requires IRB Banks to calculate total credit risk RWAs as the sum of:

●The greater of:

-1.2 x total RWAs subject to the IRB treatment (as shown in the tables in the sections Credit risk subject to the IRB approach and

Specialised lending subject to the slotting approach on pages 89 and 90 respectively); and

-0.85 x total Standardised Equivalent RWAs for each credit risk exposure subject to the IRB treatment (commonly referred to as the

standardised floor); and

●1.0 x total RWAs subject to the Standardised treatment.

The following table shows the output from these calculations, and the resulting total credit risk RWAs used in the calculation of the Bank and the

Banking Group’s total capital requirements and capital ratios as at 30 September 2025.

For each category of market risk, the Banking Group’s peak end-of-day aggregate capital charge is derived by determining the maximum over the

six months ended 30 September 2025 of the aggregate capital charge for that category of market risk derived in accordance with BPR140 Market

For the purpose of calculating the capital adequacy ratios for the Bank on a solo basis, non-SPV subsidiaries are consolidated within the Bank if

they are either funded exclusively and wholly owned by the Bank, or if there is a full, unconditional and irrevocable cross guarantee between the

Capital for other material risks

Summary of ICAAP

The Banking Group’s ICAAP outlines the Banking Group's approach to meeting minimum capital requirements and confirming that capital held by

the Bank is commensurate with its risk profile. The Banking Group’s ICAAP complies with the requirements set out in Part D of the Reserve Bank

document ‘Capital Adequacy’ (BPR100) dated 1 July 2024 in accordance with the Bank’s conditions of registration.

The Banking Group’s ICAAP identifies, reviews and measures additional material risks that must be captured within the Banking Group’s capital

adequacy assessment process. The additional material risks considered are those not captured by Pillar 1 regulatory capital requirements and

include compliance and conduct risk, liquidity and funding risk, reputational and sustainability risk, financial crime risk, other assets risk, strategic

risk and cyber risk. The ICAAP also takes account of future strategic objectives, stress testing and regulatory developments.

The Banking Group’s internal capital allocation for ‘other material risks’ is $347 million as at 30 September 2025 (30 September 2024: $295

million).

Standardised equivalent capital ratios

The following table is disclosed in accordance with Clause 17B of Schedule 11 to the Order. The Banking Group’s standardised equivalent capital

ratios are for disclosure purposes and do not form part of the Bank's Conditions of Registration. Refer to the Capital ratios sections on page 64 and

95 for the Banking Group’s capital adequacy ratios for compliance purposes.

The RWAs and capital amounts have been calculated in line with the Reserve Bank BPR standardised requirements. The capital amount has been

recalculated to exclude any capital adjustments related to the expected loss provisions that only apply under the IRB approach. The credit risk

RWAs of these exposures have been recalculated under the requirements of BPR131 Standardised credit risk RWAs. The credit risk RWAs that are

currently calculated using the standardised methodology, market risk RWAs, and operational risk RWAs remain unchanged.

2

Ultimate Parent Bank Group (excluding entities specifically excluded by APRA regulations) comprises the consolidation of the Ultimate Parent Bank and its

subsidiary entities except for those entities specifically excluded by APRA regulations for the purposes of measuring capital adequacy (Level 2). The head of the Level

2 group is the Ultimate Parent Bank.

3

Ultimate Parent Bank (Extended Licensed Entity) comprises the Ultimate Parent Bank and its subsidiary entities that have been approved by APRA as being part of a

single Extended Licensed Entity for the purposes of measuring capital adequacy (Level 1).

Under APRA’s Prudential Standards, Australian ADIs, including the Ultimate Parent Bank Group and the Ultimate Parent Bank, are required to

maintain minimum ratios of capital to risk weighted assets, as determined by APRA, which are at least equal to those specified under the Basel III

capital framework. For the calculation of RWAs, the Ultimate Parent Bank Group and Ultimate Parent Bank are accredited by APRA to apply

advanced models. The Ultimate Parent Bank Group and Ultimate Parent Bank use the Advanced IRB approach for credit risk, the Standardised

Measurement Approach (SMA) for operational risk and the internal model approach for IRRBB for calculating regulatory capital.

iv. Capital adequacy and regulatory liquidity ratios (Unaudited) (continued)
APRA has set a Total Common Equity Tier 1 (CET1) requirement for Domestic Systemically Important Banks (D-SIBs), including the Ultimate Parent

Bank, of at least 10.25% (noting that APRA may apply higher CET1 requirements for an individual bank). This requirement includes a capital

conservation buffer of 4.75% applicable to D-SIBs and a base level for the countercyclical capital buffer of 1.0% for Australian exposures which

APRA may vary between 0% and 3.5%. The total CET1 requirement is currently at least 10.25% and 10.50% effective 1 January 2027.

The Ultimate Parent Bank Board has determined a target post dividend CET1 capital ratio of above 11.25% in normal operating conditions. This

target includes consideration of APRA's increase in the minimum CET1 ratio of 0.25% to 10.50% effective 1 January 2027 and replaces the previous

CET1 capital operating range of between 11.00% and 11.50%.

APRA’s prudential standards are generally consistent with the International Regulatory Framework for Banks, also known as Basel III, issued by the

Basel Committee on Banking Supervision, except where APRA has exercised certain discretions.

The Ultimate Parent Bank Group is required to disclose additional detailed information on its risk management practices and capital adequacy on

a quarterly basis. This information is made available to users via the Ultimate Parent Bank’s website (www.westpac.com.au).

The Ultimate Parent Bank Group (excluding entities specifically excluded by APRA regulations) and Ultimate Parent Bank (Extended Licensed Entity

as defined by APRA) exceeded the minimum capital adequacy requirements as specified by APRA as at 30 September 2025.

A counterparty is a non-bank counterparty if it is a non-bank that is not a member of a group of closely related counterparties or it is a group of closely related

counterparties of which a bank is not the parent.

The peak end-of-day aggregate credit exposure to each individual counterparty (which are not members of a group of closely related

counterparties) or a group of closely related counterparties has been calculated by determining the maximum end-of-day aggregate amount of

actual credit exposure over the six-month period ending 30 September 2025, and then dividing that amount by the Banking Group’s Common

Equity Tier 1 capital as a t 30 September 2025.

Credit exposures to individual counterparties (not being members of a group of closely related counterparties) and to groups of closely related

counterparties exclude exposures to connected persons, to the central government or central banks of any country with a long-term credit rating

of A- or A3 or above, or its equivalent, or to any supranational or quasi-sovereign agency with a long-term credit rating of A- or A3 or above, or its

equivalent. These calculations relate only to exposures held in the financial records of the Banking Group and were calculated net of individually

assessed provisions.

vi. Credit exposures to connected persons
The Banking Group's credit exposure to connected persons is derived in accordance with the Bank’s conditions of registration and the Reserve

Bank document 'Connected Exposures Policy' (BS8) dated October 2023, is net of individual credit impairment allowances and excludes advances

to connected persons of a capital nature.

Credit exposures to connected persons are based on actual credit exposures rather than internal limits. Peak end-of-day aggregate credit

exposures to connected persons expressed as a percentage of Tier 1 capital of the Banking Group have been derived by determining the maximum

end-of-day aggregate amount of credit exposure over the year ended 30 September 2025 and then dividing that amount by the Banking Group’s

Tier 1 capital as at 30 September 2025.

Credit exposures to connected persons reported in the following table have been calculated on a bilateral net basis. Netting has occurred in

respect of certain transactions which are the subject of a bilateral netting agreement.

been no changes to this rating-contingent limit over the year ended 30 September 2025. Within the overall rating-contingent limit there is a sub-

limit of 15% of Tier 1 capital which applies to the aggregate credit exposure to non-bank connected persons.

Where a bank is funding a large loan it is common practice to share the risk of a customer default through risk transfer to an acceptable entity.

These arrangements are called risk lay-off arrangements. As at 30 September 2025, the Banking Group had $20 million of unfunded contingent

credit protection arrangements provided by connected persons arising from risk lay-off arrangements in respect of credit exposures to

counterparties (excluding counterparties that are connected persons).

The aggregate amount of the Banking Group's loss allowance for credit exposures to connected persons that are credit impaired was nil as at 30

September 2025.

viii. Risk management policies

Information about risk

Risk Management Framework

The Banking Group regards the management of risk to be a fundamental management activity performed at all levels of its business in support of

our purpose of taking action now to create a better future. The Banking Group’s Risk Management Framework is the totality of systems, structures,

policies, processes and people who identify, measure, evaluate, monitor, report and control or mitigate internal and external sources of material

risks.

The Banking Group's Board Risk Appetite Statement documents the Banking Group’s risk appetite settings for each of the 11 Risk Classes. The Risk

Appetite Statement is reviewed and approved annually by the Board, and is monitored and reported quarterly through the RISKCO and BRCC.

Reporting includes the details of remediation activity for any risk appetite measures outside tolerance.

The Banking Group adopts a ‘Three Lines of Defence model standard’ approach to risk management which enables all employees to understand

their role and responsibilities in the active management of risk.

The First Line of Defence owns and manages the risks they originate

Business units are responsible for proactively identifying, evaluating, owning, monitoring, managing and controlling the existing and emerging

risks in their businesses. They manage business activities within approved risk appetite and policies. In managing its risk, the First Line of Defence

establishes and maintains appropriate governance structures, controls, resources and self-assessment processes, including issue identification,

recording and escalation procedures.

The Second Line of Defence provides independent insight, oversight and challenge of First Line activities

The Banking Group's risk management function is the Second Line of Defence and reports to the Chief Risk Officer. It sets risk frameworks, policies

and standards for use across the Banking Group, including providing guidance and standards on the design, implementation, and testing of

controls (including policies and limits). The Second Line of Defence is an independent function that develops risk management frameworks,

defines guardrails, provides objective review and challenge regarding the effectiveness of risk management within the First Line business and

executes specific risk management activities where functional independence and/or specific risk capability is required. Its approach is risk-based

and proportionate to First Line activities.

The Third Line of Defence provides independent objective assurance

The Third Line of Defence is an assurance function that provides the Board, Board Committees and senior management with independent and

objective evaluation of the adequacy and effectiveness of the Banking Group’s governance, risk management and internal controls.

Financial risks

Refer to Note 31 Risk management, funding and liquidity risk and market risk for a discussion of the financial risks faced by the Banking Group.

Other key material risks

Capital adequacy risk

Capital adequacy risk is the risk that the Banking Group has an inadequate level or composition of capital to support its normal business activities

and to meet its regulatory capital requirements under both normal or stressed operating environments. Refer to Note 30 Capital management for

further details.

Operational risk

Operational risk is the risk of loss resulting from inadequate or failed internal processes, people and systems, or from external events.

Operational risk represents a category of risk that could have the potential to impact the Banking Group’s ability to achieve business objectives. In

addition, operational risk events could have a negative impact on financial performance, and/or result in poor customer outcomes and/or

reputational damage.

The Banking Group has an Operational Risk Management Framework, which is aligned to the Ultimate Parent Bank’s Operational Risk Framework

and outlines the business requirements for managing operational risk with respect to governance, risk and control assessments, incident

management, issues management and ongoing reporting and monitoring.

The Bank’s RISKCO, chaired by the Banking Group’s Chief Risk Officer, is responsible for overseeing the effectiveness and implementation of the

Operational Risk Management Framework. RISKCO monitors the operational risk profiles and the action plans and has the discretion to escalate

material matters to the Bank’s BRCC and/or the relevant Ultimate Parent Bank Group Risk Committee.

The Bank calculates Operational Risk Capital as set out in BPR150: Standardised operational risk. In addition, the Bank continues to be required to

comply with the qualitative requirements as set out in Section B1 of BPR151 AMA operational risk.

Compliance and conduct risk

Compliance and conduct risk is the risk of failing to abide by the Banking Group’s compliance obligations or otherwise failing to have behaviours

and practices that deliver suitable, fair and clear outcomes for customers and that support market integrity.

The Banking Group identifies compliance and conduct risks as part of managing the business, which includes considering emerging risks and

responding to changes in the business, business strategy and external environment. The Banking Group manages compliance and conduct risks

by implementing and embedding frameworks, systems, policies, standards, procedures and controls.

The Banking Group has a Compliance and Conduct Risk Management Framework which is supported by compliance and conduct policies to assist

the business in managing its compliance and conduct risks.

The Banking Group’s RISKCO is responsible for overseeing the effectiveness and implementation of the Compliance and Conduct Risk

Management Framework. RISKCO oversees compliance and conduct risks across the Banking Group and regularly reports material matters to the

Banking Group’s BRCC and the relevant Ultimate Parent Bank Group Risk Committee.

Financial crime risk

Financial crime risk is the risk that the Banking Group fails to prevent financial crime and/or fails to comply with applicable global financial crime

regulatory obligations. Financial crime risk includes bribery and corruption, money laundering, sanctions and export control violations, tax

evasion, fraud and scams, terrorist financing and proliferation.

The Banking Group helps prevent financial crime by proactively identifying, assessing, mitigating and reporting financial crime risks and by

complying with all applicable global and local financial crime regulatory obligations. This means that our financial crime risks must be managed

through robust controls and systems and that we must promptly own, investigate and remediate financial crime incidents where they do occur.

Cyber risk

Cyber risk is the risk that the Banking Group’s or its third parties’ data or technology are inappropriately accessed, manipulated or damaged from

cybersecurity threats or vulnerabilities.

The Banking Group proactively manages cyber risk exposure, to limit the likelihood of inappropriate access, manipulation or damage to the

Banking Group’s and its third parties’ data and technology. This includes embedding cyber security capabilities such as data security controls,

application protection controls, and identity and access management.

Reputational & sustainability risk

Reputational & sustainability risk is the risk of failing to recognise or address ESG issues and the risk that an action, inaction, transaction,

investment, or event will reduce trust in the Banking Group’s integrity and competence by clients, counterparties, investors, regulators,

employees or the public.

The Banking Group seeks to cultivate stakeholders’ trust in the Banking Group’s integrity and competence and to balance commerciality of

decisions with stakeholder expectations, potential impacts on people, communities or the environment, recognising that ESG issues can involve

complex, interconnected and at times competing considerations.

Strategic risk

Strategic risk is the risk that the Banking Group makes inappropriate strategic choices, does not implement its strategies successfully, or does not

respond effectively to changes in the operating environment.

The Banking Group manages strategic risk through annual strategic reviews and financial target setting, ongoing monitoring of performance and

changes and, stress testing and/or scenario analysis.

viii. Risk management policies (continued)
Risk culture

There is a risk that that the Banking Group’s culture does not promote and reinforce behavioural expectations and structures to identify,

understand, discuss and act on risks.

The Banking Group promotes a risk culture which supports its purpose, strategy and values and the ability to manage risk effectively. The Banking

Group regularly assesses its risk culture and undertakes initiatives to continually improve.

Capital adequacy

Refer to Note 30 Capital management for the Banking Group’s approach to assessing the adequacy of its capital to support current and future

activities and the role that directors and senior management take in the capital management process.

Reviews of the Banking Group’s risk management systems

Westpac New Zealand Audit, with support from the Ultimate Parent Bank's Group Audit unit, periodically reviews the Bank’s Operational,

Compliance and Conduct, Market, Funding and Liquidity, Credit and Model Risk Frameworks. The periodic reviews follow an internal audit

methodology which aims at achieving a review of the very high-risk areas annually, high-risk areas bi-annually, medium risk areas every three

years and low risk areas every four years.

The reviews discussed above in this section are not conducted by a party which is external to the Banking Group or the Ultimate Parent Bank,

though they are independent and have no direct authority over the activities of management.

Various external reviews of the Bank’s risk management system have been conducted during the year ended 30 September 2025 as part of

ongoing compliance with regulatory requirements.

Internal audit function of the Banking Group

The Banking Group has an internal audit function headed by the Chief Internal Auditor who reports directly to the Banking Group’s Board Audit

Committee.

The internal audit function provides independent assurance on the effectiveness of governance, risk management and internal controls across the

Banking Group’s operations. The level of risk across all material risk classes determines the scope and frequency of individual audits.

The Board Audit Committee meets regularly, and its responsibilities include the oversight of the Banking Group’s statutory financial reporting

requirements and the internal audit function.

Measurement of impaired assets

Impaired assets are measured on a monthly basis. Refer to Note 6 Impairment charges/(benefits) and Note 12 Provision for expected credit losses

which describe the approaches the Banking Group follows for assessing asset impairment.

Recoverable amounts are represented by net loans, which are calculated as gross loans less provisions for impairment.

Credit risk mitigation

Refer to Note 13.5 Credit risk mitigation, collateral and other credit enhancements and Note 25 Offsetting financial assets and financial liabilities

for the policies and processes the Banking Group follows to mitigate credit risk.

Where the effect of credit risk mitigation through eligible collateral is used to reduce our measure of risk, the Banking Group, as an Advanced IRB

Bank, uses the comprehensive method to measure the mitigating effects of the collateral or eligible guarantees.

Additional information about credit risk

Classification of Banking Group exposures by regulatory exposure class

The Banking Group determines credit risk RWAs under BPR130 Credit risk RWAs overview. The regulation specifies two different methodologies to

be applied in calculating credit risk RWAs: the standardised approach and the internal ratings based (IRB) approach (which includes the

supervisory slotting calculation method for specialised lending). For modelled exposure classes, the IRB approach applies, with total RWAs being

subject to a floor of 85% of the standardised RWAs as described in Note iv. Capital adequacy and regulatory liquidity ratios. For non-modelled

exposure classes, the standardised approach applies.

Overview of the internal credit risk ratings process by portfolio

(a)Transaction-managed approach (including business lending, corporate, Sovereign and bank)

The process for assignment and approval of individual PDs and LGDs involves business unit representatives recommending the CRGs and LGDs

under criteria guidelines. Credit Officers then independently evaluate the recommendations and approve the final outcomes. An expert judgement

decision-making process is employed to evaluate the CRG. The following represent the types of business lending, corporate, sovereign and

banking exposures included within the transaction-managed portfolio approach:

●direct lending exposures;

●contingent lending exposures;

●pre-settlement exposures;

●FX settlement exposures; and

●transaction exposures.

All of the above exposure categories also apply to Specialised Lending, which is an asset sub-class of Corporate and in the Banking Group

comprises Property Finance and Project Finance. Regulatory risk-weights are also applied to Specialised Lending.

viii. Risk management policies (continued)
Definitions, methods and data for estimation and validation of PD, LGD and EAD

PD

The PD is a through-the-cycle assessment of the likelihood of a customer defaulting on its financial obligations within one year. The Banking Group

reflects its PD estimate in a CRG.

LGD

The LGD represents an estimate of the expected severity of a loss to the Banking Group should a customer default occur during an economic

downturn. The Banking Group assigns an LGD to each credit facility, assuming an event of default has occurred, and taking into account a

conservative estimate of the net realisable value of assets to which the Banking Group has recourse and over which it has security. LGDs also

reflect the seniority of exposures in the customer’s capital and debt structure.

LGD estimates are benchmarked against observed historical LGDs from internal and external data and are calibrated to reflect losses expected in

an economic downturn. The calculation of historical LGDs is based on an economic loss and includes allowances for workout costs and the

discounting of future cash flows to the date of default.

LGD values range from 5% to 100%. The range of LGD values ensures that the risk of loss is differentiated across many credit facilities extended

to custom e r s .

EAD and CCF

EAD represents an estimate of the amount of committed exposure expected to be drawn by the customer at the time of default. The proportion of

undrawn commitments ultimately utilised by customers is termed the CCF. EAD therefore consists of the initial outstanding balances plus the CCF

multiplied by undrawn commitments.

(b)Program-managed approach (including residential mortgages, small business and other retail)

Each customer is rated using details of their account performance or application details and segmented into pools of similar risk. These segments

are created by analysing characteristics that have historically proven predictive in determining if an account is likely to go into default. Customers

are then grouped according to these predictive characteristics of default. The retail (program-managed) portfolio is divided into a number of

segments per product with each segment assigned a quantified measurement of its PD, LGD and EAD.

Retail asset class exposures included in the retail (program-managed) portfolio approach are split into the following categories of products:

Exposure classesProduct categories

Residential mortgages●Mortgages

Small business●Equipment finance

●Business overdrafts

●Business term loans

●Business credit cards

Other retail●Credit cards

●Personal loans

●Overdrafts

PD

PDs are assigned at the retail segment level and reflect the likelihood of accounts within that segment to default. A long-run average is used to

assign a PD to each account in a segment based on the segment’s characteristics. The PD estimate for each segment is based on internal data.

Models are used to help determine or establish the appropriate internal rating for program-managed portfolios.

LGD

LGD measures the proportion of the exposure that will be lost if default occurs. LGD is measured as a percentage of EAD. The approach to LGD

varies depending on whether the retail product is secured or unsecured. A downturn period is used to reflect the effect on the collateral for

secured products. For unsecured products, a long-run estimate is used for LGD.

EAD

EAD represents an estimate of the amount of committed exposure expected to be drawn by the customer at the time of default. To calculate EAD,

historical data is analysed to determine what proportion of undrawn commitments are ultimately utilised by customers who end up in default.

Additional information about operational risk

Calculating operational risk capital

Operational risk regulatory capital is calculated on a quarterly basis. Standardised operational risk capital is based on a prescribed formula

universal to all New Zealand registered banks that apply this approach to Operational Risk capital calculation.

The standardised operational risk capital requirement is the sum of two components, covering the operational risk arising on retail and

commercial banking business on the one hand and all other activities on the other. The calculation takes into account a combination of loans,

advances and securities in the retail and commercial parts of the bank and proportions of various income components for all other activities.

Controls surrounding credit risk rating systems

Refer to Note 13.1 Credit risk management framework and Note 13.2 Credit risk ratings system for a discussion of the control mechanisms for the

rating systems the Banking Group uses to measure credit risk.

Independent Auditor’s
Report

To the shareholder of Westpac New Zealand Limited (the Bank)

Report on the audit of the consolidated disclosure statement

Opinion

Within the consolidated disclosure statement we have audited the accompanying consolidated financial statements

and the supplementary information (excluding supplementary information relating to General Information and

Capital Adequacy and Regulatory Liquidity Ratios) (the financial statements and supplementary information)

which comprise:

—the consolidated financial statements comprised of:

—the balance sheet as at 30 September 2025;

—the income statement and statements of comprehensive income, changes in equity and cash flows for

the year then ended; and

—notes, including material accounting policy information and other explanatory information (excluding

the information disclosed in accordance with Schedules 2, 4, 7, 11, 13, 14, 15 and 17 of the

Registered Bank Disclosure Statements (New Zealand Incorporated Registered Banks) Order 2014

(as amended) (Order) and is included within notes 12, 13, 30 and 31 and registered bank disclosures i

to viii);

(the financial statements).

—the supplementary information that is required to be disclosed in accordance with Schedules 4, 7, 13, 14,

15 and 17 of the Order (the supplementary information), contained within note 30 and registered bank

disclosures ii, iii, v, vi, vii and viii.

We have not audited the information related to General Information and Capital Adequacy and Regulatory Liquidity

Ratios disclosed in accordance with Schedules 2 and 11 of the Order within notes 20, 21 and 31 and registered

bank disclosures i and iv, and our opinion does not extend to this information.

In our opinion, the accompanying financial statements of Westpac New Zealand Limited and its controlled entities

(the Banking Group) within pages 7 to 76:

—give a true and fair view of the Banking Group’s financial position as at 30 September 2025 and its

financial performance and cash flows for the year ended on that date; and

—comply with New Zealand Generally Accepted Accounting Practice, which in this instance means New

Zealand Equivalents to International Financial Reporting Standards (NZ IFRS) issued by the New

Zealand Accounting Standards Board and the International Financial Reporting Standards issued by

the International Accounting Standards Board.

In our opinion, the accompanying supplementary information of the Banking Group:

—presents fairly the matters to which it relates;

—is disclosed in accordance with those schedules; and

—has been prepared, in all material respects, in accordance with any conditions of registration relating to the

disclosure requirements, imposed under section 74(4)(c) of the Banking (Prudential Supervision) Act 1989.

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (New Zealand) (ISAs (NZ)). We

believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

We are independent of the Banking Group in accordance with Professional and Ethical Standard 1 International

Code of Ethics for Assurance Practitioners (Including International Independence Standards) (New Zealand) issued

© 2025 KPMG, a New Zealand Partnership and a member firm of the KPMG global organization of independent member firms affiliated with KPMG International Limited, a

private English company limited by guarantee. All rights reserved.


110Westpac New Zealand Limited

by the New Zealand Auditing and Assurance Standards Board and the International Ethics Standards Board for
Accountants’ International Code of Ethics for Professional Accountants (including International Independence

Standards) (IESBA Code), as applicable to audits of financial statements of public interest entities. We have also

fulfilled our other ethical responsibilities in accordance with Professional and Ethical Standards 1 and the IESBA

Code.

Our responsibilities under ISAs (NZ) are further described in the Auditor’s responsibilities for the audit of the financial

statements and supplementary information section of our report.

Our firm has provided other services to the Banking Group in relation to regulatory compliance assurance, climate

report limited assurance and agreed upon procedures. Subject to certain restrictions, partners and employees of our

firm may also deal with the Banking Group on normal terms within the ordinary course of trading activities of the

business of the Banking Group. These matters have not impaired our independence as auditor of the Banking

Group. The firm has no other relationship with, or interest in, the Banking Group.

Scoping

The scope of our audit is designed to ensure that we perform adequate work to be able to give an opinion on the

financial statements and supplementary information as a whole, taking into account the structure of the Banking

Group, the financial reporting systems, processes and controls, and the industry in which it operates.

The context of our audit is set by the Banking Group’s major activities in the financial year ended 30 September

2025. The Banking Group has certain operational processes which are critical to financial reporting for the Banking

Group that are undertaken outside of New Zealand. We worked with a KPMG network firm engaged in the Westpac

Banking Corporation group audit to understand and examine certain processes, test controls and perform other

substantive audit procedures that supported material balances, classes of transactions and disclosures within the

Banking Group’s financial statements and supplementary information. This enabled us to evaluate the effectiveness

of the controls over those processes and consider the implications for the remainder of our audit work.

Materiality

The scope of our audit was influenced by our application of materiality. Materiality helped us to determine the nature,

timing and extent of our audit procedures and to evaluate the effect of misstatements, both individually and on the

financial statements and supplementary information as a whole. The materiality for the financial statements and

supplementary information as a whole was set at $85 million determined with reference to a benchmark of the

Banking Group's profit before tax. We chose the benchmark because, in our view, this is a key measure of the

Banking Group's performance.

Key audit matters

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the

financial statements in the current period. We summarise below those matters and our key audit procedures to

address those matters in order that the shareholder as a body may better understand the process by which we

arrived at our audit opinion.

Our procedures were undertaken in the context of and solely for the purpose of our audit opinion on the financial

statements as a whole and we do not express discrete opinions on separate elements of the financial statements.

Provision for expected credit losses

The key audit matter

NZ IFRS 9 Financial Instruments (NZ IFRS 9) requires the recognition of expected credit losses (ECL). As disclosed

in Note 12 of the financial statements, the provision for ECL on loans was $444 million for the Banking Group at 30

September 2025. The Banking Group uses models that estimate ECL using three main components: probability of

default (PD), loss given default (LGD) and exposure at default (EAD). The Banking Group applies forward-looking

economic scenarios and associated probability weights to their models when determining an ECL estimate.

We identified the assessment of provision for ECL as a key audit matter. A high degree of audit effort, including

specialised skills and knowledge, was required because of the significant measurement uncertainty as follows:

—Model estimations: Complex and subjective auditor judgement was applied in assessing the Banking

Group’s modelled estimations of ECL due to the inherently judgmental and complex nature of the models,

namely those used to derive the PD, LGD and EAD, and key associated model assumptions. Certain

models and model assumptions are the key drivers of complexity and uncertainty, and minor changes to


Westpac New Zealand Limited111

the model assumptions could have a significant effect on the Banking Group’s calculation of the provision
for ECL.

—Economic judgements: Complex and subjective auditor judgement was applied in assessing the Banking

Group’s economic judgements, including the severity of the forward-looking downside economic scenario

and the probability weightings used in the models.

How the matter was addressed in our audit

The following are the primary procedures we performed to address this key audit matter.

—We evaluated the design and tested the operating effectiveness of certain internal controls related to the

ECL estimation process. This included certain controls relating to:

omodel validation and monitoring;

ocredit reviews that determine customer risk grades (CRGs) which is a key assumption used in the

models for a population of corporate customers; and

othe selection of the downside economic scenario and probability weightings.

Additionally, we evaluated IT general controls over key IT applications used by the Banking Group in

measuring ECL, and relevant IT application controls including those related to the transformation of critical

data elements and the flow of these from various systems into the models.

—We involved our credit risk professionals with specialised skills and knowledge who assisted in evaluating

the Banking Group’s models and associated model assumptions as follows:

oevaluating the Banking Group’s methodology used in the models to derive the PD, LGD and EAD

and associated model assumptions against criteria in the accounting standards and industry

practice;

oinspecting model code for the calculation of certain model components to assess its consistency

with the Banking Group’s modelling methodology;

oreperforming the model output for a selection of models using the Banking Group’s documented

methodology and comparing our output with the Banking Group’s outputs; and

oreperforming model monitoring for a selection of the current models to evaluate the models’

performance.

—For a selection of corporate customers, we challenged the Banking Group’s assessment of CRGs using

relevant information in the loan file including the customer’s financial position to inform our overall

assessment of the CRG against the Banking Group’s policies.

—We involved our economic and credit risk professionals with specialised skills and knowledge, who assisted

in challenging the macroeconomic variable forecasts against external economic data, evaluating the

severity of the downside economic scenario and evaluating the probability weights.

—We assessed the appropriateness of the Banking Group’s disclosures in the financial statements using our

understanding obtained from our testing and against the requirements of NZ IFRS 9.

IT Systems and Controls

The key audit matter

The Banking Group’s operations and financial reporting are highly dependent on the effective operation of IT general

controls in complex and interdependent IT systems to process and record a high volume of transactions. The

controls include those relating to user access management, change management and IT operations, as well as

automated business process controls.

We identified the IT systems and controls over financial reporting as a key audit matter as there is a risk that gaps in

the IT general controls may undermine the integrity in recording financial information and the preparation of the

financial statements. Our audit approach could significantly differ depending on the effective operations of the

Banking Group’s IT general and automated controls and reliability of system generated reports.

We involved IT specialists in assessing this key audit matter.

How the matter was addressed in our audit

We tested the control environment for key IT applications used in processing significant transactions and recording

balances in the general ledger. We also tested automated controls embedded within these systems which support

the effective operation of technology-enabled business processes. Our IT specialists were used throughout the

engagement as a core part of our audit team.


112Westpac New Zealand Limited

Our procedures included:
—User Access Management: We tested the processes by which users are granted, reviewed, and removed

from access to critical IT applications and infrastructure, including the management of privileged roles, to

assess whether access was appropriately restricted to authorised personnel.

—Change Management: We assessed the procedures governing changes to IT systems. We also evaluated

the appropriateness of users with change access to ensure segregation of duties was maintained.

—IT Operations: We tested controls over system job scheduling, issue resolution, and monitoring of system

integrity.

—Automated Business Process Controls: We reviewed system-enforced controls such as automated

reconciliations, segregation of duties, configuration-based calculations, and data integrity mechanisms to

assess their effectiveness in supporting accurate financial reporting.

Where control deficiencies were identified related to IT general controls or automated controls, we tested

compensating controls or performed additional procedures.

Other information

The Directors, on behalf of the Banking Group, are responsible for the other information. The other information

comprises information included in the annual report and disclosure statement presented in accordance with

Schedule 2 of the Order on pages 3 to 6, 77 to 82 (excluding the information on page 82 relating to registered bank

disclosure ii which forms part of the supplementary information) and 105 to 109, and the information relating to

capital adequacy and regulatory liquidity ratios disclosed in accordance with Schedule 11 of the Order within note 30

and registered bank disclosure iv, but does not include the financial statements and supplementary information and

our auditor’s report thereon. The other information also includes the Westpac New Zealand Climate Report (Climate

Report) to be published at a later date. Other than the Climate Report which we will receive at a later date, we have

received all the other information expected to be included in the annual report and disclosure statement.

Our opinion on the financial statements and supplementary information does not cover any other information and we

do not express any form of assurance conclusion thereon.

In connection with our audit of the financial statements and supplementary information our responsibility is to read

the other information and in doing so, consider whether the other information is materially inconsistent with the

financial statements and supplementary information or our knowledge obtained in the audit, or otherwise appears

materially misstated.

If, based on the work we have performed on the other information that we obtained prior to the date of the auditor’s

report, we conclude there is a material misstatement of this other information, we are required to report that fact. We

have nothing to report in this regard.

When we read the Climate Report, if we conclude that there is a material misstatement therein, we are required to

communicate the matter to directors.

Other matter

The financial statements and supplementary information of the Banking Group, for the year ended 30 September

2024 was audited by another auditor who expressed an unmodified opinion on the financial statements and

supplementary information on 3 November 2024.

Use of this independent auditor’s report

This independent auditor’s report is made solely to the shareholder. Our audit work has been undertaken so that we

might state to the shareholder those matters we are required to state to them in the independent auditor’s report and

for no other purpose.

To the fullest extent permitted by law, none of KPMG, any entities directly or indirectly controlled by KPMG, or any of

their respective members or employees, accept or assume any responsibility and deny all liability to anyone other

than the shareholder for our audit work, this independent auditor’s report, or any of the opinions we have formed.

Responsibilities of directors for the consolidated disclosure statement
The Directors, on behalf of the Banking Group, are responsible for:

—the preparation and fair presentation of the financial statements in accordance with Clause 24 of the Order;

—the preparation and fair presentation of supplementary information in accordance with Schedules 2, 4, 7,

11, 13, 14, 15 and 17 of the Order;

—implementing the necessary internal control to enable the preparation of a consolidated set of financial

statements that is free from material misstatement, whether due to fraud or error; and

—assessing the ability of the Banking Group to continue as a going concern. This includes disclosing, as

applicable, matters related to going concern and using the going concern basis of accounting unless they

either intend to liquidate or to cease operations or have no realistic alternative but to do so.

Auditor’s responsibilities for the audit of the financial statements and supplementary information

Our objective is:

—to obtain reasonable assurance about whether the financial statements and supplementary information as a

whole are free from material misstatement, whether due to fraud or error; and

—to issue an independent auditor’s report that includes our opinion.

Reasonable assurance is a high level of assurance but it is not a guarantee that an audit conducted in accordance

with ISAs NZ will always detect a material misstatement when it exists.

Misstatements can arise from fraud or error. They are considered material if, individually or in the aggregate, they

could reasonably be expected to influence the economic decisions of users taken on the basis of the financial

statements and supplementary information.

A further description of our responsibilities for the audit of the financial statements and supplementary information is

located at the External Reporting Board (XRB) website at:

Independent Limited
Assurance Report

To the shareholder of Westpac New Zealand Limited (the Bank)

Report on the supplementary information relating to Capital Adequacy and Regulatory Liquidity Ratios

Conclusion

Our limited assurance conclusion has been formed on the basis of the matters outlined in this report.

Based on our limited assurance engagement, which is not a reasonable assurance engagement or audit,

nothing has come to our attention that would lead us to believe that the supplementary information relating to

Capital Adequacy and Regulatory Liquidity Ratios, disclosed in registered bank disclosure iv within the

consolidated disclosure statement, is not, in all material respects disclosed in accordance with Schedule 11 of

the Registered Bank Disclosure Statements (New Zealand Incorporated Registered Banks) Order 2014 (as

amended) (the Order).

Information subject to assurance

We have reviewed the supplementary information relating to Capital Adequacy and Regulatory Liquidity Ratios, as

disclosed in registered bank disclosure iv within the consolidated disclosure statement for the period ended 30

September 2025.

Criteria

The supplementary information relating to Capital Adequacy and Regulatory Liquidity Ratios comprises the

information that is required to be disclosed in accordance with Schedule 11 of the Order.

Standards we followed

We conducted our limited assurance engagement in accordance with Standard on Assurance Engagements 3100

(Revised) Compliance Engagements (SAE 3100 (Revised)) issued by the New Zealand Auditing and Assurance

Standards Board (Standard). We believe that the evidence we have obtained is sufficient and appropriate to provide

a basis for our limited conclusion. In accordance with the Standard, we have:

—used our professional judgement to plan and perform the engagement to obtain limited assurance that

the supplementary information relating to Capital Adequacy and Regulatory Liquidity Ratios, are free

from material misstatement and non-compliance, whether due to fraud or error;

—considered relevant internal controls when designing our assurance procedures, however we do not

express a conclusion on the effectiveness of these controls;

—ensured that the engagement team possesses the appropriate knowledge, skills and professional

competencies;

—obtained an understanding of the process, models, data and internal controls implemented over the

preparation of the information relating to Capital Adequacy and Regulatory Liquidity Ratios;

—performed inquiry and analytical procedures over the Capital Adequacy and Regulatory Liquidity Ratios;

—obtained an understanding of the Bank’s compliance framework and internal control environment over the

information relating to Capital Adequacy and Regulatory Liquidity Ratios, including the Bank’s assessment

of any matters of non-compliance with the Reserve Bank of New Zealand’s Prudential Requirements; and

—agreed the information relating to Capital Adequacy and Regulatory Liquidity Ratios, extracted from the

Bank’s models, accounting records or other supporting documentation to the consolidated disclosure

statement

How to interpret limited assurance and material misstatement and non-compliance
In a limited assurance engagement, the assurance practitioner performs procedures, primarily consisting of

discussion and enquiries of management and others within the entity, as appropriate, and observation and walk-

throughs, and evaluates the evidence obtained. The procedures selected depend on our judgment, including

identifying areas where there is a risk of material misstatement and non-compliance with Schedule 11 of the Order.

The procedures performed in a limited assurance engagement vary in nature and timing from and are less in extent

than for a reasonable assurance engagement. Consequently, the level of assurance obtained in a limited assurance

engagement is substantially lower than the assurance that would have been obtained had a reasonable assurance

engagement been performed.

Misstatements, including omissions, within the supplementary information relating to Capital Adequacy and

Regulatory Liquidity Ratios and non-compliance are considered material if, individually or in aggregate, they could

reasonably be expected to influence the relevant decisions of the intended users taken on the basis of the

supplementary information relating to Capital Adequacy and Regulatory Liquidity Ratios.

Inherent limitations

Because of the inherent limitations of an assurance engagement, together with the internal control structure it is

possible that fraud, error or non-compliance with compliance requirements may occur and not be detected.

A limited assurance engagement for the period ended 30 September 2025 does not provide assurance on whether

compliance with Schedule 11 of the Order will continue in the future.
