Temperatures are set to take a wintry turn as a sudden cold snap hits parts of the country.
Everywhere in the South Island will fall below 10C with Queenstown set to fall to a chilly 4C.
Central and lower North Island regions across the North Island will also shiver with Masterton on an unsummer-like 8C and Taupo on 9C.
The rest of the island will also feel the effects of the sudden cold snap with overnight temperatures sitting around or just above 10C.
MetService forecaster Chester Lampkin warned it would be a chilly January night ahead, especially for the South Island and inland parts of the North Island.
The good news was the weather would get better this afternoon making way for a calmer day tomorrow.
However, more bad weather was set to return late Saturday with more heavy rain for the already saturated West Coast.
