After a day of scattered rain, the temperature dips into the minus figures in some parts of the country tonight before wet and wild weather hits tomorrow.
The temperature is set to dip to -1C in Christchurch tonight, -3C in Ashburton and -2C in Queenstown.
It comes after the country gets a good sprinkling of rain with isolated showers expected this afternoon in Northland, Auckland, Coromandel and Bay of Plenty.
Scattered showers are also expected to stretch from Waikato to Kāpiti, including Taupō, Taumarunui, and Taihape.
Similarly rain is expected in Wairarapa and Wellington, while Gisborne and Hawke's Bay avoid the drizzle with fine but cloudy weather.
A deep low over the north Tasman Sea is expected to move southeast across the North Island tomorrow, bringing rain and strong winds, and snow to the Central Plateau.
A trough should move northeast across the country throughout Thursday and early Friday, followed by strong, cold southwesterlies.
Yesterday, WeatherWatch warned the milder weather would turn bleaker and windier as the week wore on, particularly on Friday.
"The set up this week will again produce heavy snow in the mountains and ranges of both islands, heavy rain [mostly North Island] and windy weather nationwide by late week," WeatherWatch predicted.
"The windiest weather later this week looks to hug coastal areas but especially central and eastern areas of both islands on Friday.
"There may be a few power cuts but generally winds look below damaging threshold despite being blustery."
