On Wednesday we have another ridge over the upper North Island, which connects to two large areas of high pressure – one to the east of the North Island, and another to the west, out in the Tasman Sea.

The rest of the country is covered by a gusty northwesterly airflow.
High temperatures prevail in the east of both islands, with high cloud in the east of the South Island at times.
The West Coast is mainly cloudy, with rain about South Westland, and the odd shower northwards at times, up through to around Greymouth.
