Wild weather is also expected for the central North Island but the rest of the country continues to bask in summer's glow as we head into the last weekend of the year.
MetService yesterday issued a severe weather warning for northern Hawke's Bay, saying heavy rain may cause surface flooding and slips, making driving dangerous.
Hikers and campers are being warned to stay away from the ranges in the northern Hawke's Bay and swimming holes might also become unsafe as stream and river levels rise rapidly.
The break in the extraordinarily sunny start to summer is being caused by a ridge lying over the South Island and a low deepening east of the North Island.
The low is expected to move slowly eastwards today as the ridge spreads across the country.
Looking ahead to New Year's Eve, MetService says a front will move over the South Island on Saturday and Sunday, while a complex low approaches the country from the northwest on Monday.
This means while yesterday and today are mainly fine, much of the country can expect increasing cloud and showers over the weekend with rain heralding the New Year on Monday.
For Northland and Auckland, New Year's eve is set to be a sunny one, but rain is predicted to arrive the following day.
Whanganui to Wellington will be fine and cloudy through the weekend with a few showers mainly about the ranges on Monday.
