The North Island is set to get more heavy rain this week, with Taranaki expected to be hit hardest.
Periods of heavy rain and thunderstorms will move across central New Zealand on Monday, and MetService has warned of surface flooding.
Bursts of heavy rain will drench the far south of the North Island and the far north of the South Island. The heaviest falls are expected in northern Taranaki where a heavy rain warning is now in force.
Last week bad weather in Taranaki caused power outages, also in Rotorua and Hawke's Bay.
Severe weather warnings have been issued in south Taranaki, Waitomo, Taumaranui and western Taihape including Tongoriro National Park. Rainfall in these areas is expected to approach "warning criteria" with 50 to 70mm of rain expected to fall in six to nine hours.
Warnings have also been issued to Horowhenua Kapiti Coast and Wellington including the Tararua Range, the Marlborough Sounds and Nelson west of Motueka, where rainfall is expected to reach warning amounts.
In Taranaki, where the heaviest rain is expected to fall, the most intense rain is likely Monday morning and afternoon until around 4pm, according to MetService.
Heavy showers are also expected to hit Auckland.
