New Zealanders might need to break out the electric blankets this week as a large high-pressure system makes its way across the country, bringing freezing temperatures with it.

The belt of high pressure stretches thousands of kilometres and will creep across the country this weekend.

Before it hits Kiwis can expect settled weather throughout the week - parts of the North Island are forecast to reach 17C.

However as the weekend sets in, temperatures are forecast to plummet with the arrival of the high-pressure system.

Metservice meteorologist Lewis Ferris told Newshub Kiwis can expect a drop.

"As we head into the weekend, that high pressure will lock in those colder temperatures that come with winter," he said on Monday.

"High pressure will bring clear skies and no wind so there is a chance it will get pretty cold."

Inland parts of the South Island like central Otago can expect to wake up to -3C on Sunday morning while other regions like Mount Cook will shiver at temperatures of -2C and -1C over both weekend days. 

The high could spell trouble for the North Island with well-below-normal weekly rainfall expected.

NIWA forecasts just 3mm will fall in Auckland and even less in the Bay of Plenty with a puny 1.1mm forecast.

"Not ideal for those continuing to deal with water deficits," a spokesperson for NIWA posted on Twitter.
