A front, preceded by a strong northwest flow, in bringing rain to the South Island in the next few days. But from Monday this front moves northwards over the North Island, with rain, and may become slow-moving over the northern North Island late in the day.
There is low confidence of rainfall amounts reaching warning criteria about the Tararua Range, Northern Taranaki (including on the mountain) and the ranges of eastern Bay of Plenty and far northern Gisborne/Tairawhiti on Monday.
There is also low confidence of northwesterlies reaching severe gale about exposed parts of North Canterbury, Marlborough, Wellington and Wairarapa during the first half of the day.
The front should generally move off the country on Tuesday, but may linger over the north of the North Island. A south or southeast wind change follows the front, with a ridge spreading over central and southern New Zealand.
The Manawatū-Wanganui Coastal Zone will be moving to a restricted fire season on Friday 12 January at 8am, until further notice, Fire and Emergency NZ said.
