A passenger ferry was forced to make a marathon seven-hour journey crossing Cook Strait to skirt around high seas whipped up by storm force winds.
The Bluebridge ferry tried to dodge the worst of the wild weather which last night saw 4-metre swells and southerly winds tipping just under 100km/hwhip through the passage.
A storm warning remains in force for Cook Strait but the towering seas and strong winds are expected to gradually drop throughout the day.
Strait Shipping spokesman Ed Menzies said in order to make the trip more comfortable for passengers the ship's master took a more southbound course and slowed down vessel which avoided the worst of the swell but meant the journey took seven hours, four hours longer than normal.
The return sailing out of Wellington did not take any passengers for comfort reasons, he said.
The overnight gales, which caused chaos on capital waterfront roads, brought down trees and delays to the city train network, ushered in one of the coldest weeks of the year with a stinging cold front laced with air direct from Antarctica sitting over the country.
With snow already falling in the South Island high country and mountain ranges of the central North Island temperatures are expected to plunge to single digits everywhere.
Auckland will see its coldest night this year with a chilly 6C and Christchurch is set to freeze on 0C.
The big chill has already hit southernmost towns with Alexandra recording an overnight low of -1C.
MetService is forecasting cold gale force southerlies to many regions across New Zealand. Wellington was expected to be battered by fierce gusts of up to 100 km/h today which were not expected to die down until after lunch.
While winds hammering the eastern coast of the North Island are expected to ease in the next eight hours, a new cold front will see the country's southernmost regions in the firing line for the next blast of gale northwesterlies.
MetService today issued a fresh weather watch for northwest gales developing over the South Island Tuesday with the possibility of destructive gales in Fiordland, Southland, Otago and parts of Canterbury.
A heavy rain warning has already been issued for Fiordland.

Police were this morning advising motorists heading to work and school to take care on the capital's roads, with many harbourside roads still affected by flooding.
A Fire Service spokeswoman said the worst of the weather seemed to end at midnight. She was expecting a flurry of fresh calls once daybreak revealed the extent of the damage.
