A low front will cross the country from the west tonight and early on Monday morning, bringing bursts of heavy rain to western and central areas, it said.
Heavy rain could cause rivers and streams to rise rapidly, cause surface flooding and slips and make driving conditions hazardous, MetService said.
Up to 120 millimetres of rain are forecast for Mount Taranaki in the 12 hours from 1pm today, with up to 90mm expected to fall in northwest Nelson up until 7pm tonight and up to 100mm in the Westland ranges south of Ōtira up until 1am on Monday.
MetService warned wind gusts in Auckland could be strong enough to damage trees, powerlines and unsecured structures.
A strong wind warning has been issued for Auckland with gales of up to 110km per hour in exposed places from 3pm until 9pm tonight.
Auckland power company Vector is on high alert ahead of winds forecast to be up to 110km per hour in exposed places from 3pm until 9pm tonight. Its chief networks officer Andre Botha said the company is prepared for any power cuts caused by the weather.
