In the South Island rain was expected to soak western parts of the island with heavy rain warnings in place for Fiordland and Westland.
MetService warned residents in the area that between 140mm and 200mm of rain could accumulate from midnight Sunday through to 8pm tonight.
On the east coast Christchurch was forecast to have a fine warm day while Dunedin could expect cloudy cooler conditions and rain in the evening.
Yesterday Northland saw the highest levels of rainfall in the North Island, recording 68mm at a MetService station.
In Auckland, 14mm was recorded as rain persisted throughout the day.
MetService meteorologist Ciaran Doolin said the rain had been brought on by a front running along the east of the North Island.
"That has been bringing a fair bit more precipitation than we were expecting. We have been seeing that [yesterday] afternoon."
Mr Doolin said it was really Northland that had accumulated the most substantial rainfall.
