More rain is on the way on Wednesday, the result of another sub-tropical low bringing warm, moist air down from the Tropics and fueling some wet weather in New Zealand.

Rain will be heavy for the upper North Island at times – with heavy falls easing in the evening, as gusty northeast winds change southwest – and there’s a possibility of thunderstorms with it, too.
Rain may have eased about Northland by afternoon.
Cloudy conditions for most of the lower North Island, and rain moves in during the afternoon – changing to heavy falls by evening, especially in the east, from Gisborne to Wairarapa.
Easterlies over the lower North Island should tend southeast by evening.

For the South Island, high cloud dominates for the upper South Island, along with winds from the east or northeast.
Cloudier skies hang about Nelson and Marlborough, with showers or drizzle from afternoon.
The lower South Island is mainly sunny, with light winds tending west to northwest in Southland, while overnight a few showers move in along with a southwest change.
