A high pressing in across the country could mean another frosty night for many parts of the country.
The weather is also far from settled in some regions, with cold southerly and sleet expected in some regions this evening.
A high rolling in overnight and into tomorrow will see frosts likely develop in both islands, Weatherwatch's Philip Duncan said.
As the last of the southerly blast moves through the eastern regions, Gisborne can also expect strong winds and rain/showers later today.
