Spring's wild weather is continuing with heavy rain forecast to pound the upper North Island over the next couple of days.

High winds and rain yesterday sent trees crashing down in Auckland, while many areas in the North Island copped a battering of rain and thunderstorms.

A large tree fell across a busy street in central Auckland, blocking two lanes in Wellesley St heading towards Hobson St outside the St Matthew-in-the-City church.

MetService is warning more of the same with the Coromandel expected to receive heavy rain overnight and strong winds becoming severe in exposed places.

A low moving to the east of the North Island will also bring gale-force winds to Northland and Auckland, starting from tomorrow afternoon through to Friday morning.

In Gisborne, heavy rain may cause streams and rivers to rise rapidly. Surface flooding and slips are also possible and driving conditions may be hazardous, said MetService.

Overnight, Gisborne could notch up a further 50 to 70mm of rain on top of what has already fallen. Thunderstorms are also on the cards.

The Chatham Islands are also in for a battering from winds approaching severe gale in exposed places from tomorrow afternoon until Friday morning.

MetService said the weather is being driven by a complex low and associated fronts forecast to move southeast across northern New Zealand tonight and tomorrow.

A heavy rain warning remains in place for the far north of Gisborne
