Recent Emergency Response Efforts in Waipara

Following a substantial weather event on July 11, the Waipara River began rising fast, eroding the ground under a MainPower pole. Without urgent attention and intervention, the pole could haven fallen into the river cutting power to approximately 2,300 connections around Amberley and surrounding areas. If this situation were to occur it could take up to 24 hours to restore power, with the requirement for a helicopter to re-string the lines across a river to span a new pole.

The MainPower team quickly established an Emergency Operations Centre (EOC) to review the situation and decide on a course of action to take. Once the EOC decided on a solution, a five-man field crew was dispatched, along with an external crane operator and 20 tonne digger to install a new pole 15 metres behind the existing pole.

Affected residents were notified via radio, social media and emails to prepare for a power outage. The power to Amberley and some surrounding areas, was switched off just after 7pm. While originally meant to be a 10-hour job, the fantastic team managed to get the power back on before midnight.

Hot water load testing under way ahead of winter

Until mid‑April, we’re working closely with retailers to carry out hot water load testing as we prepare our network for the coming winter season.

These tests run for a couple of hours each day, Monday to Friday, with no testing taking place over weekends. Because each test window is relatively short, customers are unlikely to notice any changes to their hot water supply.

The purpose of this work is to help us better understand how much controllable load is available during the summer months. Gaining accurate insights now means we can model customer savings more effectively by reducing system load at peak times. It also helps us assess whether this load flexibility could assist Transpower in deferring an upcoming local transmission upgrade.

This testing is an important part of ensuring a resilient, efficient network that supports our community.

Treat all lines as live during the outage period; power may be restored at any time. If you require further information, please call MainPower’s 24-hour faults line. To report an emergency, call 111.
