OPERATIONAL PERFORMANCE FOR THE
3 MONTHS ENDED 30 SEPTEMBER 2025

Operational performance highlights:

• 634,269 electricity network connections, up 1.2% on September 2024
• 2,460 GWh electricity volume distributed in the period, up 1.3% on September 2024
comparative period.
Commentary:

The three months ended 30 September 2025 has seen network connection numbers continue
to grow across Vector’s Auckland electricity network. In the year to 30 September 2025, total
electricity connection numbers grew by 1.2%. However, new connections for the three months
ended 30 September 2025 are 7.0% lower than in the three months to 30 September 2024.
Electricity distributed volume was up 1.3% compared with the three months ended 30
September 2024, largely correlating with cooler temperatures where more electricity is used
for heating. Residential volumes were up 1.6% while business volumes were up 1.0%.

There has been a 0.1% decrease in total connections on Auckland’s gas distribution network
over the year to 30 September 2025. New gas connections in the three months to 30
September 2025 were down 47.2% on the same period last year. There was a net reduction
of 156 customers in the September 2025 quarter. Gas distribution volume for the three months
to 30 September 2025 was down 2.7% compared with the prior comparative period, due to
lower demand from the residential, industrial and commercial sectors.

SAIDI minutes for normal operations (planned) for the six months ended 30 September 2025
is lower than the prior comparative period reflecting our on-going focus on preventive
maintenance and vegetation management. SAIDI minutes for normal operations (unplanned)
for the six months ended 30 September 2025 is higher than the prior comparative period and
includes the impact of Cyclone Tam, which also triggered a Major Network Event beginning
on the 15
th
of April 2025 and lasting until mid-morning of the 18
th
of April. We note that SAIDI
results are preliminary and subject to audit.
