Westpac Banking Corporation - New Zealand Banking Group

Note 1 Financial statements preparation
These financial statements have been prepared in accordance with the Order and Generally Accepted Accounting Practice, as appropriate for for-

profit entities, and the New Zealand equivalent to International Accounting Standard 34 Interim Financial Reporting. They also comply with

International Accounting Standard 34 Interim Financial Reporting as issued by the International Accounting Standards Board. These financial

statements do not include all the notes of the type normally included in annual financial statements. Accordingly, they should be read in

conjunction with the annual financial statements included in the Disclosure Statement for the year ended 30 September 2025.

The financial statements were authorised for issue by the Board of Directors of the Overseas Bank on 12 May 2026.

Accounting policies

The accounting policies adopted in the preparation of these financial statements are consistent with those in the annual financial statements for

the year ended 30 September 2025, except for certain hedge accounting changes as outlined below. The going concern concept has been applied.

Effective 1 October 2025, the NZ Banking Group adopted the hedge accounting requirements of NZ IFRS 9 Financial instruments. As permitted by

NZ IFRS 9, the adoption of these requirements is considered a change in accounting policy for the NZ Banking Group and is applied prospectively.

As the accounting for macro hedging activities of interest rate risk is not explicitly addressed in NZ IFRS 9, the NZ Banking Group will continue to

apply NZ IAS 39 Financial Instruments: Recognition and Measurement hedge accounting principles for its portfolio-level fair value hedging of retail

products.

NZ IFRS 9 simplifies hedge accounting by more closely aligning hedge relationships with the NZ Banking Group’s risk management strategies and

allows a broader range of hedged items and hedging instruments to be designated. Certain cost-of-hedging elements may now be deferred i n

other comprehensive income (OCI) in a cost of hedging reserve (COHR). In addition, the hedge effectiveness testing is less prescriptive. Whereas

NZ IAS 39 requires hedge effectiveness to be within a range of 80%–125% or otherwise hedge accounting is discontinued, NZ IFRS 9 instead

requires a qualitative assessment of whether an economic relationship exists between the hedged item and the hedging instrument and also

permits rebalancing for hedge relationships where effectiveness levels have changed.

All the NZ Banking Group’s existing hedge accounting relationships previously designated under NZ IAS 39 continued to qualify for hedge

accounting under NZ IFRS 9 and comparative information has not been restated. Under NZ IFRS 9, costs of hedging (cross-currency basis

spreads) are being reflected in a new COHR within OCI. The balance of the COHR as at 31 March 2026 is $(25) million (30 September 2025: Nil).

All amounts in these financial statements are presented in New Zealand dollars and have been rounded to the nearest million dollars unless

otherwise stated.

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 these financial statements.

Critical accounting assumptions and estimates

In preparing the interim financial statements, the application of the NZ Banking Group’s accounting policies requires the use of judgement,

assumptions and estimates. The areas of judgement, assumptions and estimates in these financial statements, including the key sources of

estimation uncertainty, are consistent with those in the Disclosure Statement for the year ended 30 September 2025. Recent geopolitical

developments have led to a higher than usual degree of uncertainty with the assumptions and estimates used to determine the provision for ECL.

Actual outcomes may differ significantly from the assumptions used. Details of the specific judgements in relation to the calculation of the

provision for ECL including overlays are included in Note 7.

Amendments to Accounting Standards effective this period

Except for certain hedge accounting changes as outlined above, no new accounting standards have been adopted by the NZ Banking Group for the

six months ended 31 March 2026. There have been no amendments to existing accounting standards that have had a material impact on the NZ

Banking Group.

As at 31 March 2026, $7,537 million of residential mortgages, accrued interest (representing accrued interest on the outstanding residential

mortgages) and cash (representing collections of principal and interest from the underlying residential mortgages) were used by the NZ Banking

Group to secure the obligations of WSNZL under the CB Programme (30 September 2025: $7,539 million).

In addition, $18 million of residential mortgages and accrued interest have been pledged as collateral as part of the repurchase agreements with

the Reserve Bank, under the Term Lending Facility (30 September 2025: $1,532 million under the Term Lending Facility and Funding for Lending

Programme (which was fully repaid during the period ended 31 March 2026)).

The pledged assets were not derecognised from the NZ Banking Group’s balance sheet in accordance with the accounting policies outlined in

Note 1 Financial statements preparation included in the Disclosure Statement for the year ended 30 September 2025. As at 31 March 2026, the

New Zealand dollar equivalent of bonds issued by WSNZL under the CB Programme was $5,020 million (30 September 2025: $6,613 million) and

the cash value of the repurchase agreements with the Reserve Bank was $15 million (30 September 2025: $1,134 million).

Note 7 Provision for expected credit losses

Loans and credit commitments

Movements in components of loss allowance

The reconciliation of the provision for ECL for loans and credit commitments has been determined by an aggregation of monthly movements over

the period. The key line items in the reconciliation represent the following:

●“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 period.

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

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

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

repayments and additional drawdowns on existing facilities over the period.

●"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 NZ 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 are 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).

Note 7 Provision for expected credit losses (continued)
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 $21 million (30 September 2025: $17 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 $3 million (30 September 2025: $2 million) for the NZ Banking Group. These estimates

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

The following table discloses the macroeconomic scenario weightings applied by the NZ Banking Group as at 31 March 2026 and 30 September

2025.

(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 over estimation 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 NZ Banking Group’s total portfolio overlays as at 31 March 2026 were $(7) million (30 September 2025: $(27) million).

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

●Stage 1 gross carrying amount had a net increase of $3.7 billion (30 September 2025: increased by $12.4 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 the increase in exposures, primarily driven by underlying portfolio movements and a more conservative

economic outlook.

●Stage 2 gross carrying amount decreased by $1.0 billion (30 September 2025: decreased by $8.2 billion), primarily driven by the movement

of exposures to Stage 1 from residential mortgages and corporate lending along with repayments. The Stage 2 ECL increase is primarily from

management overlay, along with an impact from a weaker economic outlook, partially offset by underlying portfolio movements.

●Stage 3 gross carrying amount decreased by $0.04 billion (30 September 2025: increased by $0.1 billion), reflecting gross movements of

exposures between Stage 3 and Stage 2, along with repayments, resulting in a small net reduction over the period. The increase in Stage 3

ECL is largely driven by new IAPs.

Note 11 Fair values of financial assets and financial liabilities

Fair Valuation Control Framework

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

Valuation techniques

The NZ 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:

Analysis of movements between fair value hierarchy levels

The NZ Banking Group considers transfers between levels, if any, to have occurred at the end of the reporting period. During the period, there

were no material transfers between levels of the fair value hierarchy.

Standby letters of credit and guarantees are undertakings to pay, against presentation of documents, an obligation in the event of a default by a customer.

Guarantees are unconditional undertakings given to support the obligations of a customer to third parties. The NZ Banking Group may hold cash as collateral for

certain guarantees issued.

2

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

the notional amounts do not necessarily reflect future cash requirements.

3

In addition to the commitments disclosed above, there is $2,903 million (30 September 2025: $1,358 million) of exposure to credit risk relating to credit exposures

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

Contingent assets

The NZ 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 NZ 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; and internal investigations and

reviews.

The scope of reviews (internal and external), investigations and inquiries 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 NZ 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.

Notes to the financial statements

Westpac Banking Corporation - New Zealand Banking Group21

Note 13 Segment reporting
The NZ Banking Group operates predominantly in the Consumer Banking and Wealth, Institutional and Business Banking and Financial Markets,

International Trade and Payments 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 NZ Banking Group does not rely on any single major customer for its revenue base.

Segment comparative information for the six months ended 31 March 2025 and as at 30 September 2025 has been revised to align to the current

period's basis for reporting, and is consistent with the information provided internally to the NZ Banking Group's chief operating decision-maker.

This includes changes in the segmentation classification for small to medium enterprise customers.

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

identified the following main operating segments:

●Consumer Banking and Wealth provides financial services for individuals and small to medium enterprise;

●Institutional and Business Banking provides a broad range of financial services for corporate, property finance, agricultural, institutional and

government customers; and

●Financial Markets provides foreign exchange, interest rate derivatives, fixed interest and debt securities, commodities, carbon and energy

capabilities. International Trade and Payments provide international trade solutions, payments products and services to consumer,

business and institutional 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/aggregation of the results, assets and liabilities of the NZ Banking Group’s controlled entities in the

preparation of the aggregated financial statements of the NZ Banking Group; and

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

the NZ Banking Group for statutory financial reporting purposes.

Other material matters

Reserve Bank review of overseas bank branches

On 30 October 2025, the Reserve Bank released the exposure draft of the Incorporation outside New Zealand Standard (IoNZ Standard) under the

Deposit Takers Act 2023. The proposed IoNZ Standard will require that overseas bank branches only conduct business with wholesale clients; the

total size of an overseas bank's branch not exceed NZ$15 billion in total assets; the New Zealand business be less than 50% of its total business;

and dual-operating branches (such as the NZ Branch) only conduct business with “large corporate or institutional clients" (LCIC).

The IoNZ Standard proposes that LCIC includes (broadly) those with consolidated annual turnover of over NZ$50 million or total assets of over

NZ$75 million and funds management entities and custodians with total assets under management of over NZ$250 million. 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

Westpac New Zealand. We expect the Reserve Bank's IoNZ Standard will require changes to the activities the NZ Branch undertakes and as a

result, Westpac New Zealand may also make changes to the scope of the activities it undertakes.

Reserve Bank capital review

On 17 December 2025, the Reserve Bank announced its decisions relating to its review of key capital settings for deposit takers (2025 Capital

Review). Once implemented, the updated settings for Group 1 deposit takers (including Westpac New Zealand) will:

●remove AT1 from the capital stack and phase out the recognition of existing AT1 instruments.

●require the deposit taker to have a Common Equity Tier 1 (CET1) capital ratio of 12% (including a 6% PCB ratio).

●require the deposit taker to have a total capital ratio of 15% (including a 6% PCB ratio). Up to 3% of the total capital ratio requirement can

consist of subordinated debt eligible as Tier 2 capital to be issued to the Australian parent bank.

●require the deposit taker to have an additional 6% of RWAs of Loss Absorbing Capacity (LAC) instruments to be issued to the Australian

parent bank, bringing the total requirement including LAC to 21%.

●introduce more granular and lower standardised risk weights for certain asset classes.

The new Tier 2 and LAC instruments will include conversion to equity or write-off provisions.

On 27 February 2026, the Reserve Bank released further information relating to the 2025 Capital Review, including further information on indicative

transition timelines and confirmation it will continue to consider applications for redemption of AT1 instruments, subject to the relevant prudential

requirements being satisfied.

On 13 April 2026, the Reserve Bank published an exposure draft consultation to update the BPRs for some of the decisions made as part of the

2025 Capital Review. For Group 1 deposit takers (including Westpac New Zealand) these draft BPRs propose, as an interim measure, permitting

the issuance of Tier 2 instruments with a shorter maturity date or earlier redemption date than is permitted under the current settings.

Additionally, a separate amortisation table for Tier 2 instruments issued with a maturity date of less than 5 years has been proposed.

The Reserve Bank has also indicated it intends to consult during 2026 on the new Tier 2 and LAC instrument design and related implementation

timelines.

APRA to consult on enhancements to bank capital and liquidity frameworks

On 16 March 2026, APRA announced that it will consult on a package of reforms to bank capital and liquidity settings. The consultation will be run

in three workstreams focusing on credit risk capital, liquidity risk and market risk, which include the following proposals:

●Targeted amendments to the standardised capital framework to increase risk sensitivity and better align capital requirements with

underlying risk.

●Changes to the liquidity framework including consideration of a new Pillar 2 liquidity framework to address risks not covered by existing

Liquidity Coverage Ratio minimum requirements.

●Implementation of a simplified version of the Basel Committee’s Fundamental Review of the Trading Book standard.

APRA has indicated that it will release a consultation paper in respect to the credit risk capital workstream in the first half of the 2026 calendar

year with industry engagement and consultation for the liquidity and market risk workstreams to continue into 2027.

Australian Anti-Money Laundering and Counter-Terrorism Financing (AML/CTF) Reforms

In 2024, the Australian Parliament enacted the Anti-Money Laundering and Counter-Terrorism Financing Amendment Act 2024 (Cth), introducing

major reforms to the AML/CTF regime. A substantial number of reforms took effect from 31 March 2026. The reforms include the extension of a

number of provisions (including customer due diligence obligations) that apply to the Overseas Bank's permanent offshore establishments,

including Westpac New Zealand, BT Funds Management (NZ) Limited (BTNZ) and NZ Branch. In response, the Overseas Bank and the NZ Banking

Group are updating their policies, procedures, systems and controls, and are taking steps to address compliance gaps. Full implementation will

require a multi-year implementation plan for the Overseas Bank and its permanent offshore establishments, including complex technology

upgrades to customer due diligence, expanding transaction monitoring and reporting infrastructure. Timing and delivery challenges are an

industry wide issue. In recognition of these challenges, the AML/CTF Transitional Rules (Transitional Rules) commenced alongside the new regime,

providing legislative transitional arrangements for a limited subset of obligations applicable to existing reporting entities, including deferred

commencement of certain requirements, subject to specified conditions. These Transitional Rules do not, however, apply to the Overseas Bank's

Registered bank disclosures

i. General information (continued)
permanent offshore establishments. Given the scale of changes required, the NZ Banking Group has not completed implementation of all new

requirements as at 31 March 2026.

AUSTRAC has also published its regulatory expectations, noting that it does not expect immediate compliance, provided reporting entities

continue to effectively identify, mitigate and manage money laundering and terrorism financing risk and show sustained effort and reasonable

progress against their implementation plans. During this period, AUSTRAC expects existing AML/CTF controls to continue to operate.

The Overseas Bank has developed, and continues to refine, a phased implementation plan, that addresses both obligations subject to transitional

arrangements and broader reforms not covered by the Transitional Rules, including those applicable to its permanent offshore establishments.

The Overseas Bank will continue to engage with AUSTRAC to support a phased implementation approach.

AUSTRAC related class action against Overseas Bank

The Overseas Bank is defending a class action proceeding which was commenced in December 2019 in the Federal Court of Australia on behalf of

certain investors who acquired an interest in the Overseas Bank's securities between 30 June 2014 and 19 November 2019. The proceeding

involves allegations relating to market disclosure issues connected to the Overseas Bank’s monitoring of financial crime over the relevant period

and matters which were the subject of the AUSTRAC civil proceedings. The total damages sought on behalf of members of the class have not been

specified. However, in the course of a procedural hearing in August 2022, the applicant indicated that a preliminary estimate of the losses that

may be alleged in respect of a subset of potential group members exceeded AU$1 billion. While it remains unclear how any damages awarded (if

the applicant succeeded) would be determined and its size, it is possible that the claim may be higher or lower than the amount referred to above.

Given the time period and the nature of the allegations, along with the reduction in the Overseas Bank's market capitalisation at the time of the

commencement of the AUSTRAC civil proceedings, it is likely that any total alleged damages sought by the applicant will be significant. The

Overseas Bank continues to deny both that its disclosure was inappropriate and, as such, that any group member has incurred damage. The Court

has made orders for a hearing to commence on 5 April 2027 with an estimated duration of six weeks.

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 NZ 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 NZ Banking Group manages based on their contractual maturity are presented on a contractual undiscounted

basis in the following table.

iv. Credit and market risk exposures and capital adequacy

Additional mortgage information

Residential mortgages by LVR as at 31 March 2026

LVRs are calculated as the current exposure divided by the NZ Banking Group’s valuation of the associated residential property at origination.

The NZ 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 NZ 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.

Market risk

The NZ Banking Group’s aggregate market risk exposure is derived in accordance with BPR140 Market risk exposure and is calculated on a six-

monthly basis. The end-of-period aggregate market risk exposure is calculated from the period end balance sheet information.

For each category of market risk, the NZ Banking Group’s peak end-of-day aggregate capital charge is derived in accordance with the scalar

approach as referred to in BPR140 Market risk exposure. Under this approach, the end-of-period capital charge is scaled by the ratio of peak

capital charge to end-of-period capital charge using the internal value-at-risk method.

The following table provides a summary of the NZ Banking Group’s notional capital charges by risk type as at the reporting date and the peak end-

of-day notional capital charges by risk type for the six months ended 31 March 2026:

The capital ratios represent information mandated by APRA. The capital ratios of the Overseas Banking Group are publicly available in the Overseas Banking Group’s

Pillar 3 report. This information is made available to users via the Overseas Bank’s website (www.westpac.com.au).

2

Overseas Banking Group (excluding entities specifically excluded by APRA regulations) comprises the consolidation of the Overseas 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

Overseas Bank.

3

Overseas Bank (Extended Licensed Entity) comprises the Overseas Bank and its subsidiary entities that have been approved by APRA as being part of a single

Extended Licensed Entity for the purpose of measuring capital adequacy (Level 1).

Under APRA’s Prudential Standards, Australian authorised deposit-taking institutions, including the Overseas Banking Group and Overseas 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 Overseas Banking Group and Overseas Bank are accredited by APRA to

apply advanced models. The Overseas Banking Group and Overseas 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.

APRA has set a Total Common Equity Tier 1 (CET1) requirement for Domestic Systemically Important Banks (D-SIBs), including the Overseas 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%.

On 4 December 2025, APRA published the final changes to the relevant prudential and reporting standards resulting from the phase out of AT1

with an effective date of 1 January 2027. Under the revisions, large internationally active banks such as the Overseas Bank will replace 1.5% of AT1

capital with 1.25% of Tier 2 capital and 0.25% of CET1 capital. The total CET1 requirement, including regulatory buffers, will increase from 10.25%

to 10.50%. There is no overall increase in total capital requirements for banks.

On implementation of these revised prudential and reporting standards, existing AT1 capital instruments would be included in the calculation of

the amount of total capital, until their first scheduled call date. Existing Overseas Bank AT1 capital instruments would reach their first scheduled

optional redemption dates by 2031 at the latest.

In addition, effective 1 January 2027 the minimum leverage ratio requirement will be 3.25% based on CET1 capital replacing the current

requirement of 3.50% based on Tier 1 capital. APS 221 Large Exposures and APS 222 Associations with Related Entities exposure limits remain

unchanged, however will be based on CET1 capital rather than Tier 1 capital.

The Overseas Bank Board has determined a target post dividend CET1 capital ratio of above 11.25% in normal operating conditions.

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 Overseas Banking Group is required to disclose information on its capital adequacy on a quarterly basis. This information is made available to

users via the Overseas Bank’s website (www.westpac.com.au).

The Overseas Banking Group (excluding entities specifically excluded by APRA regulations), and the Overseas Bank (Extended Licensed Entity as

defined by APRA), exceeded the minimum capital adequacy requirements as specified by APRA as at 31 March 2026.

Independent Auditor’s
Review Report

To the New Zealand business of Westpac Banking Corporation (the Branch)

Report on the aggregated interim disclosure statement

Conclusion

Within the aggregated interim disclosure statement we have completed a review of the accompanying

aggregated half-year financial statements and the supplementary information (excluding supplementary

information relating to General Information and Credit and Market Risk Exposures and Capital Adequacy) (the

half-year financial statements and supplementary information) which comprise:

–the aggregated half-year financial statements comprised of:

–the balance sheet as at 31 March 2026;

–the income statement and statements of comprehensive income, changes in equity and cash

flows for the 6 month period then ended; and

–notes, including material accounting policy information and other explanatory information

(excluding the information disclosed in accordance with Schedules 3, 5, 7, 9, 12 and 14 of the

Registered Bank Disclosure Statements (Overseas Incorporated Registered Banks) Order 2014

(as amended) (the Order) and is included within notes i to vi);

(the half-year financial statements).

–the supplementary information that is required to be disclosed in accordance with Schedules 5, 7, 12

and 14 of the Order (the supplementary information), contained within registered bank disclosures ii,

iii, v and vi.

Based on our review, the accompanying half-year financial statements and supplementary information of the

New Zealand business of Westpac Banking Corporation and its financial reporting group, as defined by the

Order, (the NZ Banking Group) within pages 6 to 23 and 27 to 36, nothing has come to our attention that

causes us to believe that:

–the half-year financial statements have not been prepared, in all material respects, in accordance

with New Zealand Equivalent to International Accounting Standard 34 Interim Financial Reporting

(NZ IAS 34); and

–the supplementary information that is required to be disclosed in accordance with Schedules 5, 7, 12

and 14 of the Order:

–does not present fairly, in all material respects, the matters to which it relates;

–is not disclosed, in all material respects, in accordance with those schedules; and

–has not been prepared, in all material respects, in accordance with any condition of registration

relating to disclosure requirements imposed under section 74(4)(c) of the Banking (Prudential

Supervision) Act 1989.

Basis for conclusion

We conducted our review in accordance with NZ SRE 2410 (Revised) Review of Financial Statements Performed

by the Independent Auditor of the Entity (NZ SRE 2410 (Revised)). Our responsibilities are further described in

the Auditor's responsibilities for the review of the half-year financial statements and supplementary information

section of our report.

We are independent of the NZ Banking Group in accordance with the relevant ethical requirements in New

Zealand relating to the audit of the annual disclosure statement and we have fulfilled our other ethical

responsibilities in accordance with these ethical requirements.

Our firm has provided other services to the NZ 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 NZ Banking Group on normal terms within the ordinary course of
trading activities of the business of the NZ Banking Group. These matters have not impaired our independence

as auditor of the NZ Banking Group. The firm has no other relationship with, or interest in, the NZ Banking

Group.

Use of this Independent Auditor's Review Report

This report is made solely to the Branch. Our review work has been undertaken so that we might state to the

Branch those matters we are required to state to them in the Independent Auditor’s Review 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 responsibility and deny all liability to anyone

other than the Branch for our review work, this report, or any of the conclusions we have formed.

Responsibilities of directors for the aggregated interim disclosure statement

The Directors, on behalf of the NZ Banking Group, are responsible for:

— the preparation and fair presentation of the NZ Banking Group’s aggregated interim disclosure

statement in accordance with NZ IAS 34 and Schedules 3, 5, 7, 9, 12 and 14 of the Order; and

— implementing necessary internal control to enable the preparation of aggregated interim disclosure

statement that is fairly presented and free from material misstatement, whether due to fraud or error.

Auditor's responsibilities for the review of the half-year financial statements and

supplementary information

Our responsibility is to express a conclusion on the half-year financial statements and supplementary information

based on our review.

NZ SRE 2410 (Revised) requires us to conclude whether anything has come to our attention that causes us to

believe that the:

— half-year financial statements, taken as a whole, do not present fairly, in all material respects, the NZ

Banking Group’s financial position as at 31 March 2026 and its financial performance and cash flows for

the 6 month period ended on that date;

— half-year financial statements, taken as a whole, do not, in all material respects, comply with NZ IAS 34;

and

— the supplementary information does not, fairly state, in all material respects, the matters to which it

relates in accordance with Schedules 5, 7, 12 and 14 of the Order.

A review of the half-year financial statements and supplementary information in accordance with NZ SRE 2410

(Revised) is a limited assurance engagement. The auditor performs procedures, consisting of making enquiries,

primarily of persons responsible for financial and accounting matters, and applying analytical and other review

procedures.

The procedures performed in a review are substantially less than those performed in an audit conducted in

accordance with International Standards on Auditing (New Zealand) and consequently does not enable us to

obtain assurance that we might identify in an audit. Accordingly, we do not express an audit opinion on the half-

year financial statements and supplementary information.

The engagement partner on the review resulting in this independent auditor’s review report is Sonia Isaac.

Assurance Report

To the New Zealand business of Westpac Banking Corporation (the Branch)

Report on the supplementary information relating to Credit and Market Risk Exposures and Capital

Adequacy Requirements

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

Credit and Market Risk Exposures and Capital Adequacy Requirements, disclosed in registered bank

disclosure iv within the aggregated interim disclosure statement, is not, in all material respects disclosed in

accordance with Schedule 9 of the Registered Bank Disclosure Statements (Overseas Incorporated

Registered Banks) Order 2014 (as amended) (the Order).

Information subject to assurance

We have reviewed the supplementary information relating to Credit and Market Risk Exposures and Capital

Adequacy Requirements, as disclosed in registered bank disclosure iv within the aggregated interim disclosure

statement for the period ended 31 March 2026. Our conclusion on the Credit and Market Risk Exposures and

Capital Adequacy Requirements does not extend to any other information included, or referred to, in the

aggregated interim disclosure statement.

Criteria

The supplementary information relating to Credit and Market Risk Exposures and Capital Adequacy

Requirements comprises the information that is required to be disclosed in accordance with Schedule 9 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.

Our responsibilities under the Standard are further described in the 'Our responsibility' section of our report.

How to interpret limited assurance and material misstatement and non-compliance

A limited assurance engagement is substantially less in scope than a reasonable assurance engagement in

relation to both the risk assessment procedures, including an understanding of internal control, and the

procedures performed in response to the assessed risks.

Misstatements, including omissions, within the supplementary information relating to Credit and Market Risk

Exposures and Capital Adequacy Requirements 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 Credit and Market Risk Exposures and Capital Adequacy

Requirements.

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 31 March 2026 does not provide assurance on whether

compliance with Schedule 9 of the Order will continue in the future.

Use of this assurance Report

This report is made solely for the Branch. Our assurance work has been undertaken so that we might state to the

Branch those matters we are required to state to them in the assurance report and for no other purpose.

Our report should not be regarded as suitable to be used or relied on by anyone other than the Branch for any

purpose or in any context. Any other person who obtains access to our report or a copy thereof and chooses to

rely on our report (or any part thereof) will do so at its own risk.

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 Branch for our work, for this independent assurance report, and/or for the opinions or

conclusions we have reached.

Our conclusion is not modified in respect of this matter.

Directors' responsibility for the supplementary information relating to Credit and Market Risk

Exposures and Capital Adequacy Requirements

The Directors of the Branch are responsible for the compliance activities undertaken to meet their identified

compliance requirements and disclosure of the supplementary information relating to Credit and Market Risk

Exposures and Capital Adequacy Requirements in accordance with Schedule 9 of the Order. This responsibility

includes such internal control as the Directors determine is necessary to enable the identification of risks that

threaten the compliance requirements being met, designing and implementing controls which will mitigate those

risks, monitor ongoing compliance and to enable the disclosure of the supplementary information relating to

Credit and Market Risk Exposures and Capital Adequacy Requirements that is free from material misstatement

and non-compliance whether due to fraud or error.

Our responsibility

We have responsibility for:

- planning and performing the engagement to obtain limited assurance about whether the supplementary

information relating to Credit and Market Risk Exposures and Capital Adequacy Requirements is free

from material misstatement and non-compliance, whether due to fraud or error;

- forming an independent conclusion based on the procedures we have performed and the evidence we

have obtained; and

- reporting our conclusion to the Branch.

Our work was carried out by a multidisciplinary team, including specialists in Financial Risk Management, who

assisted with the procedures below. We remain solely responsible for the assurance conclusion.

Summary of the work we performed as the basis for our conclusion

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 judgement, including

identifying areas where the risk of material misstatement and non-compliance with Schedule 9 of the Order is

likely to arise.

We exercised professional judgment and maintained professional skepticism throughout the engagement. We

designed and performed our procedures to obtain evidence about the compliance activities and controls

implemented to meet the requirements of Schedule 9 of the Order.

In undertaking limited assurance, the procedures we primarily performed were:

40Westpac Banking Corporation - New Zealand Banking Group

- obtained an understanding of the process, models, data and internal controls implemented over the
preparation of the information relating to Credit and Market Risk Exposures and Capital Adequacy

Requirements;

- performed inquiry and analytical procedures over the Credit and Market Risk Exposures and Capital

Adequacy Requirements;

- obtained an understanding of the Branch’s compliance framework and internal control environment over

the information relating to Credit and Market Risk Exposures and Capital Adequacy Requirements,

including the Branch’s assessment of any matters of non-compliance with the Reserve Bank of New

Zealand’s Prudential Requirements; and

- agreed the information relating to Credit and Market Risk Exposures and Capital Adequacy

Requirements, extracted from the Branch’s models, accounting records or other supporting

documentation to the consolidated disclosure statement

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.

Our independence and quality management

We have complied with the independence and other ethical requirements of Professional and Ethical Standard 1

International Code of Ethics for Assurance Practitioners (including International Independence Standards) (New

Zealand) (PES 1) issued by the New Zealand Auditing and Assurance Standards Board, which is founded on

fundamental principles of integrity, objectivity, professional competence and due care, confidentiality and

professional behaviour.

The firm applies Professional and Ethical Standard 3 Quality Management for Firms that Perform Audits or

Reviews of Financial Statements, or Other Assurance or Related Services Engagements (PES 3), which requires

the firm to design, implement and operate a system of quality control including policies or procedures regarding

compliance with ethical requirements, professional standards and applicable legal and regulatory requirements.

Our firm has also provided other services to the Branch 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 Branch on normal terms within the ordinary course of trading activities of the

business of the Branch. These matters have not impaired our independence as assurance providers of the Bank

for this engagement. The firm has no other relationship with, or interest in, the Branch.
