A few light showers spread along the east coast of the North Island on Wednesday, risk of a shower late afternoon / evening for the upper North Island otherwise a mainly sunny day beforehand.

A mostly cloudy day for the eastern South Island, the odd light shower about especially morning. Some sun may break through from late afternoon about coastal areas and Southland / Otago. Mainly sunny for the West Coast, a few showers possible Greymouth northwards from afternoon.
