Currently, two cold fronts are located at both ends of New Zealand. The northern front faces away to the northeast direction, so the weather is gradually expected to improve over the North Island. Meanwhile, the cold front located at the south end of NZ will move northeast across the South Island while weakening. This front will bring rain and a little snow in the highlands, over the South Island.

On early Wednesday this is followed by high pressure, and associated ridges is expected to cover NZ. But on late Wednesday a new front is forecast to approach from the southwest and move into the West Coast. On Thursday this front may bring heavy rain over southwestern parts of the South Island.
