It looks like winter is set to make a comeback this week, with 140km/h gales possible in Auckland as well as snow and rain across the country.
Forecaster WeatherWatch says strong winds will mainly impact the western North Island and Auckland on Wednesday, with the strongest gusts in places such as the Manukau Heads and Kaipara Harbour.
Auckland looks to be most exposed on Wednesday afternoon, with some power cut potential, a spokesperson said.

This rain band over the upper South Island will move right across the North Island today, starting with Wellington and Taranaki later this morning. There's a risk of thunderstorms and hail in western regions.
As temperatures plunge on Wednesday behind the cold front, rain will turn to snow, the spokesperson said.
The North Island's central plateau could receive 15-20cm of snowfall from Tuesday night to Wednesday. More than one metre is likely to accumulate on the summits of the South Island's West Coast over the next week.
A few snow flurries - lighter and unlikely to settle - are expected to low levels in Southland and Otago on Wednesday.
And with the wild weather comes wild swells, with MetService urging caution on the water.
Dangerous coastal conditions are expected along the west coasts of both islands on Wednesday and Thursday.
"Very long period southwesterly swell and high waves are forecast. These waves carry a lot of energy - extra caution around the coast is recommended," a spokesperson said.
