Weather: Power cuts, dangerous waves as strong winds slam New Zealand

Strong winds howled through New Zealand on Saturday, causing power cuts and dangerous waves.

MetService has issued a strong wind watch for Northland, Auckland, Coromandel Peninsula, and Banks Peninsula until 6pm - and is urging Kiwis to take care.

"Currently some disruptions being experienced for Aucklanders as Strong Winds affect the area," it tweeted.

"The video below shows the strong winds affecting the country currently and how it eases tonight."

Lines company Vector says there have been multiple power outages mostly affecting parts of west and north Auckland this morning.

"As a result of strong winds, the network lost several feeders and one zone substation supplying power to multiple areas," a spokesperson said.

"The outages were caused by strong winds causing lines to clash, or by trees and vegetation blowing onto lines."

Waikato police are calling for motorists to also take care with the strong winds and rain.

Emergency services attended an incident this afternoon after a tourist bus was blown off the road. No one was injured, but police say it's a good reminder to "take it easy in this weather".

On top of the power cuts, there is also some heavy southwest swell affecting Northland and Auckland's west coasts.

"Here is a snapshot of the significant wave height around midday today for 5.5-6.5m, this should be easing from tonight," MetService tweeted.
