Temperatures are set to dive this week with Kiwis in the centres of both the North and South islands being warned of the risk of frost.
Weatherwatch advises a cold southerly flow will move up New Zealand over Tuesday and Wednesday, pushing temperatures downwards.
The lower two-thirds of the country will experience below-average temperatures for most of Tuesday before the chilly air eventually reaches the upper North Island in the evening.
According to Metservice, Auckland will see a low of 9C on Tuesday, Hamilton will hit 6C, Wellington will fall to 8C and Dunedin will have a low of 4C. Christchurch and Queenstown will both fall down to 0C.
It will be a cold start to the morning on Wednesday, with Weatherwatch warning of a frost risk for most of central South Island, including the Queenstown Lakes district. However, as the day wears on, temperatures will slowly start to return to normal for most regions.
"Wednesday night will be another cold night going into Thursday morning with more frosts possible as high pressure grows, locking in the colder air," Weatherwatch says.
Thursday morning's frosts are likely to be in central parts of the South Island as well as on the North Island's Central Plateau.
"Drier than usual weather will also be setting in as this powerful high pressure belt moves in (and will linger for the first week of May)."
But before that happens, much of the country will be doused in rain.
Metservice says there will be showers across New Zealand on Tuesday, especially in the morning and early afternoon. Most of the North Island, from Northland to Kapiti, as well as the Chatham Islands may also experience thunderstorms.
