Conditions about the inner South Island especially Central Otago will be frosty tonight, despite the lows shown below expect colder temperatures with -3 to -4 expected. The North Island with plenty of cloud cover / rain and wind keeps any frosts at bay.
Tomorrow eastern parts of the country will feel colder than average, those in the west a bit warmer. Auckland northwards experiences humid conditions and the countries top temperatures with 16 to 18 degrees expected. Very cold about Central Otago, some parts not escaping 4 to 5 degrees.

Why don’t frosts occur with strong winds?

There’s too much mixing of the air with strong winds. Here’s an excerpt from a website I’ve found about frosts:
“Wind is a great tool to help disperse pockets of cold air—which is why frosts only tend to occur on still evenings. Mixing the lower part of our atmosphere, wind prevents ground temperatures from plummeting by bringing in less cold air from other locations or even from the upper atmosphere.”
Hope that helps.
