A significant wintry outbreak is set to grip much of New Zealand on Sunday and Monday.

“The low pressure system affecting the North Island over the next few days should depart into the Pacific this weekend,” said MetService Weather Ambassador Bob McDavitt.  “As it moves away on Sunday, a strong and very cold southerly flow is expected to sweep across New Zealand.”

According to MetService, this polar outbreak is likely to bring gale force winds, as well as snow showers to very low levels, to southern and eastern parts of both islands on Sunday or Monday.

McDavitt pointed out that this event will coincide with lambing season. “The combination of cold winds and rain or snow is likely to bring extreme wind chill, causing significant stress to new-born livestock.  Farmers should make plans now for the likelihood of a few days of wind-blown snow.”

This snow is also likely to disrupt transport; those planning to travel should check for the latest updates to Severe Weather Outlooks, Watches and Warnings at, or for mobiles, at
