Wild weather: 25,000 homes and businesses lost power, fallen trees in Auckland

About 25,000 homes and businesses in and north of Auckland lost power this afternoon as stormy weather rocked the region.

It was a cold afternoon for some in the Warkworth, Wellsford, Kaiwaka, Maungaturoto, Ruawai and Mangawhai areas, with power knocked out about 3.30pm.

A Transpower spokeswoman said power was restored by about 6pm.

"It was an unexpected and unplanned outage in bad weather conditions," she said.

"We are going to pick up the investigation again at first light so we can't confirm at this stage [what caused the power cut]."

Wild weather has also brought down trees in the suburb of Mt Wellington, briefly causing power to be cut to the area.

Firefighters were called to the scene in Banks Rd, Mt Wellington, this afternoon where trees had fallen across a residential road, pulling at least one power pole down with them.

A Fire and Emergency spokeswoman said damage to three power poles and a car was reported.

A Vector spokeswoman said power was now back on in that area.

"For community safety reasons, we shut down power to the area for around an hour to allow for crews to arrive on site and assess what had happened," she said.

MetService meteorologist Lewis Ferris earlier told the Herald Auckland had been under a strong wind watch, and in the hour leading up to 3.30pm the strongest gust recorded near the site was 78km/h.

The forecast for Auckland includes gusts up to 110km/h, and other parts of the city show gusts between 80 and 100km/h.

"We've been expecting the strong winds for the last couple of days," Ferris said.

Today it has been "somewhat stormy" in Auckland with strong winds, showers, and a little bit of hail.

But locals can look forward to a "relatively nice" next few days, with the bad weather expected to ease later today.

"Everything basically wraps up tonight," Ferris said.

"The strong wind watch is due to expire at 8pm ... overnight those winds will pull back."

There may still be a bit of wind on Thursday morning, but the weather should clear throughout the day and give Auckland a "relatively nice run" for a couple of days.
