More wild weather will lash New Zealand next week bringing rain, thunderstorms and strong winds while temperatures are set to plummet across the country.
According to MetService, a "moist northerly airstream" will bring heavy rain to northern and western parts of the South Island, as well as deluge to northern and western parts of the North Island.
The forecaster warns the rain band, which brought heavy rain to Nelson, Tasman and Marlborough on Saturday, will move south to the West Coast on Sunday, where it will stall for a couple of days.
"On Tuesday we expect it to reinvigorate and move back eastwards delivering another round of heavy rain to the country," the service said.
NIWA has also warned about the onset of wild weather, saying temperatures will plummet from unusually warm to unusually cold.
"With big temperature changes, comes very active weather," NIWA said.
NIWA warns thunderstorms could be "especially active and widespread" on Tuesday with a high chance of lightning strikes for the upper North Island, including Hamilton, Tauranga, Auckland and Northland.
NIWA also warns that strong winds will lash parts of the country from Tuesday through to Thursday.

There are still 10 weather warnings and watches in place around the country, with MetService urging Kiwis to keep up to date with the latest forecasts.
