Low pressure will cross over the South Island on Friday night bringing more heavy rain to western and northern parts of the island and some spillover into the east too. The North Island has showers and patchy rain developing tonight, but the front will break up as it moves over the north.

Thunderstorms are likely off the Tasman Sea with heavy downpours, they will be more isolated for the North Island.

The colder change arrives in the South Island over Saturday and by Sunday all of NZ should have the colder winds, bringing in frost potential to the South Island by Monday morning and then potentially into the North Island next week.

High pressure is moving towards southern NZ by the end of next week bringing drier weather to most regions, but some showers will continue in Southland, Hawke’s Bay and Gisborne areas in particular.
