An easterly quarter airflow lies over the North Island on Tuesday and this brings the odd shower to east / northeastern areas. Mainly dry conditions in the west. For the South Island a front coming out of a low in the Tasman Sea brings rain to the West Coast as can be seen below, a few spits or showers may spread further eastwards.
A similar situation continues on Wednesday for the North Island meanwhile further south the aforementioned front slips a little further southwards along the West Coast and weakens.
This coming Thursday and incoming system from the southwest brings heavy rain to the West Coast of the South Island, this front moves onto the western North Island on Friday but it does weaken.
