Weather events impacting network

Significant winds yesterday and fires in the Kaikōura region have impacted the MainPower network, with crews currently out fixing faults and restoring power. 

Acting Chief Executive Damien Whiffen says the company has stood up its Emergency Operations Centre (EOC) to ensure resources and supplies are directed to the areas that need them most. 

“We’re keenly aware that some of our customers were without power last night, and looking at the forecast for Thursday which includes significant wind across the network, we are encouraging our customers to enact their No Power Plans and prepare to be without power for some days if the weather delivers as promised. 

“Our crews are currently out scoping and fixing faults, but the fires in Kaikōura and the remote nature of much of our network means this will take time. We are stocking up and preparing for a significant event tomorrow.” 

MainPower has over 46,000 customers on the network in the Waimakariri, Hurunui and Kaikōura regions. In 2023 a similar weather pattern meant around half the network was without power for extended periods, so the company is preparing for the worst. 

“Of course we hope we’re overcooking this and it won’t be as bad as the forecasts would have us believe, but we’re making sure we have everything we need on hand – from poles to people – to get to those repairs as soon as it’s safe to do so,” Whiffen says. 

“We’re particularly mindful of our customers and crews in Kaikōura, many of whom are volunteer firefighters and are working around the clock to keep their community safe.” 

There are currently around 600 customers without power in the Kaikōura, Lees Valley, Waikari, Culverden and Waiau areas. The company hopes to restore power to as many of these areas today before the wind picks up again tomorrow.

We’re making great progress restoring power across the network. Currently there are 85 customers without power, but we have a large number of crews in multiple locations again today.

We will have a helicopter operating in the Hurunui Mouth area around midday today. The helicopter is a twin engine and is carrying out complex river crossing repairs. It will be travelling low and slow, and it will be quite loud.

Please keep the area clear so our teams can carry out these urgent repairs to restore power to the area.
