The North Island is bracing for impact as Cyclone Vaianu approaches.

It was a calm morning for much of the country, but numerous weather warnings, including a rare red wind warning for the Coromandel Peninsula and Great Barrier Island, were in place.

Category-2 Cyclone Vaianu was forecast to be a "very large, damaging system", according to MetService.

In Northland, a State of Emergency has been declared as a precautionary measure for an initial period of seven days.

The cyclone was expected to make landfall on Sunday, with the entire North Island and Eastern Marlborough under some form of weather watch or warning.

According to MetService, the Fair North will be the first to experience strong winds, heavy rain, and rough seas brought by Vaianu from late Saturday.

Cyclone Vaianu approaches the North Island Saturday morning.

Overnight and into Sunday, the storm will move south-eastwards across the North Island.

"The combination of damaging winds, heavy rain, and coastal inundation makes this a multi-hazard, potentially life-threatening event," the forecaster said.

"The locations of the most severe impacts associated with Cyclone Vaianu, such as power outages, falling trees, flooding, slips, road closures, and isolated communities, are highly dependent on the cyclone's track.

"People are urged to keep up to date with the latest forecasts, adjust plans as needed and be prepared to act, following all advice of local authorities."

MetService will be updating it's weather warnings at 10am today.

1News meteorologist Dan Corbett said last night that the swirl was still "quite active" with "good flare-ups" to the centre, meaning it "still had some punch".

Corbett said that wind and rain would hit the Far North in the early hours of Sunday, then Rodney, and parts of Auckland.

He said "piling wind gusts" would arrive in the Coromandel later in the day.

"This could be potentially nasty," he said.

MetService said there could be severe gale easterlies changing to severe gale west to northwesterlies for the Coromandel on Sunday afternoon, with "damaging" gusts of 140km/h. Winds would start to ease throughout the afternoon as Vaianu moves south.

As Sunday goes on, Vaianu will move south towards the lower North Island and upper South Island, bringing heavy rain and high winds of up to 130 km/h in some exposed places.

"This is going to be a nasty thing," Corbett said.

People in affected areas were urged to be prepared.

This included charging phones and power banks, having a battery-powered radio to listen for updates, preparing a grab bag for everyone in your household, making an evacuation plan, and tying down anything strong winds could pick up, like trampolines.
