A big high is rolling in and despite a gentle southerly flow most places look mostly sunny and settled this weekend.

Overnight lows in the North Island will be mostly, if not entirely, in the single digits with a few light frosts through the interior of both islands.

A front in the Southern Ocean will lift up the westerlies and drive in some cloud later on Sunday across southern parts of the South Island, with windy weather and another cool change arriving on Monday in the south.
