OPERATIONAL PERFORMANCE FOR THE
YEAR ENDED 30 JUNE 2025

Operational performance highlights:

• 632,106 electricity network connections, up 1.2% on June 2024
• 120,621 gas network connections, up 0.2% on June 2024
Commentary:

The year ended 30 June 2025 has seen network connection numbers continue to grow across
Vector’s Auckland electricity and gas networks. In the year to 30 June 2025, total electricity
connection numbers grew by 1.2%. However, new connections in the year ended 30 June
2025 have been 21.4% lower than in the year to 30 June 2024, reflective of the broader
economic slowdown. Electricity distributed volume was down 1.4% compared with the year
ended 30 June 2024, largely correlating with warmer temperatures where less electricity is
used for heating. This is reflected in residential volumes being down 2.9% while business
volumes were down 0.1%.

There has been a 0.2% increase in total connections on Auckland’s gas distribution network
over the year to 30 June 2025. However, new gas connections in the year to 30 June 2025
were down 33.0% on the prior year. Gas distribution volume for the year to 30 June 2025 was
down 8.5% compared with the prior year, due to lower demand from the residential, industrial
and commercial sectors.

SAIDI minutes for normal operations (planned) for the three months ended 30 June 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 three months ended 30 June 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.
