Weather: Cold blast brings 'winter-like temperatures'

A fast-moving cold blast has hit New Zealand on Saturday, leaving behind "winter-like temperatures" in the South Island as it moves up the country.

"A front is making its way northwards over New Zealand today leaving another cold airmass in its wake," MetService says.

"This is a fast-moving feature and will end just south of Auckland by tonight."

NIWA says it's going to be windy in the South Island and lower North Island, with westerlies becoming southerly.

There will also be "winter-like temperatures" in the South Island, arriving in the lower/eastern North Island on Sunday.

Rain radar shows the front bringing rain to northern Westland, and Buller across to Canterbury.

"Severe weather watches are in force for wind, rain and snow along the South Island currently as the front leaves another cold airmass in its wake," MetService says.

Road snowfall warnings have been issued for Lewis Pass, Arthur's Pass, Porters Pass, Lindis Pass, Crown Range Rd, and Milford Rd.
