We have a significant cool change arriving on Friday with many in the South Island dropping from the low to mid 30s to the late teens and early 20s, a drop of 10 to 14 degrees for some.

The cool change moves into the North Island on Saturday with the eastern side noticing it the most after your very hot week. However those in the northern quarter of the country may barely notice it with a hot, mostly dry, weekend on the cards for many.

Waitangi Day looks unsettled for some with a cold front moving up the South Island (colder than the one we have coming tomorrow) while the North Island may see afternoon downpours with muggy conditions. We’ll continue to keep you posted.
