An unseasonable cold snap will be felt in much of the country over the weekend as a front moves over the North Island.
Auckland will be spared the chill, MetService forecasting a high for the city of 17degC today and long fine spells with isolated showers.
"It's sort of missing out on the colder temperatures of a cold front going through," meteorologist Derek Holland said.
Hamilton could expect much the same, with slightly more cloud cover.
Down in Wellington, locals weren't so lucky, with a high of 12 predicted and showers this morning followed by more rain in the evening.
"We've got a cold front crossing over the North Island today," Holland said.
"It's got cold air behind it so we've got an unseasonably cold snap, possibly becoming frosty in sheltered inland areas in the central North Island and South Island.
The frost could be a nuisance for gardeners in inland areas, he warned.
Those in coastal areas didn't need to worry about frost killing off their summer gardens.
Christchurch was also forecast to be chilly today, with southwesterlies, showers and the possibility of snow about the hill tops of Banks Peninsulas predicted.
It would be clearer on the west coast of South Island, mostly fine in Westland with a few showers in Bula.
The maximum temperature for Greymouth and Hokitika was about 15 today, Holland said.
From tomorrow the rain would start to clear, with a few showers in the far south but generally increasing sunny spells over the whole country.
Temperatures weren't due to pick up until Monday or Tuesday and mornings might still could be frosty on Sunday and Monday for those inland on both islands, Holland said.
