OPERATIONAL PERFORMANCE FOR THE
3 MONTHS ENDED 30 SEPTEMBER 2026

Operational performance highlights:

• 644,577 total electricity network connections, up 1.6% on September 2025
• 3,478 new electricity network connections, up 8.8% on September 2025 quarter
• 2,491 GWh electricity volume distributed, up 1.3% on September 2025 quarter.

Commentary:

Auckland’s electricity network continues to grow, with total electricity connection numbers up
1.6% in the year to 30 September 2026.

New connections for the three months ended 30 September 2026 are 8.8% higher than in
the three months ended 30 September 2025. Electricity distributed volume was up 1.3%
compared with the three months ended 30 September 2025, with residential volumes up
2.3% and business volumes up 0.2%. Cooler winter temperatures, particularly in July 2026,
saw more electricity used for heating.

There has been a 0.6% decrease in total connections on Auckland’s gas distribution network
over the year to 30 September 2026. New gas connections in the three months ended 30
September 2026 were down 18.9% on the same period last year. There was a net reduction
of 285 customers in the September 2026 quarter. Gas distribution volume for the three months
ended 30 September 2026 was down 2.8% compared with the prior comparative period, due to
lower demand from the industrial and commercial sectors.

SAIDI minutes for normal operations (unplanned) for the six months ended 30 September 2026
have more than halved against the prior comparative period. Performance has been supported
by favourable weather, a low incidence of adverse events, and the sustained benefits of
reliability improvement initiatives. There have been no Major Network Events during the period,
while the prior comparative period included the impact of one Major Network Event when the
Auckland region was affected by Cyclone Tam. SAIDI minutes for normal operations (planned)
for the six months ended 30 September 2026 are higher than the prior comparative period
however still within the regulatory threshold. We note that SAIDI results are preliminary and
subject to audit.
