Weather: North Island downpour triggers king tide warning

The forecast for Christmas isn't looking too flash after Monday morning's downpour. 

Floodwaters have forced the evacuation of a motor camp in southern Coromandel.

Emergency services were called to Top 10 Holiday Park at Waihi just before 3am Monday morning, when the grounds were inundated with water.

A Fire and Emergency spokesperson says campers were moved to the local RSA as a precaution.

MetService forecaster Andy Downs told Newshub the heavy rain could cause localised surface flooding and "maybe even more significant surface flooding" in some places. 

King tides are forecast for Auckland's Tamaki Drive, Tauranga, and the Firth of Thames.

"Over 90mm of rain has fallen this morning in Tauranga - hourly rates up to 20mm an hour," Mr Downs said on Monday. 

An image posted by MetService on Sunday captured the bleak Auckland weather with heavy clouds looming over the City of Sails. 

Showers and heavy rain have set in across the North Island which is set to ease overnight, says Weather Watch - but don't expect a flash Christmas Day. 

Rain or showers are predicted for most of the North Island on Christmas Day, with heavy rain expected for the Bay of Plenty and Waikato. 

The forecast for the South Island isn't looking too flash either, with rain or showers predicted for Nelson and Marlborough, while showers are also expected for Christchurch. 

However, the southern South Island is set to have more settled Christmas Day weather.  

It's all because of a "large low" looming over New Zealand, says Weather Watch. 

Christmas Day will bring "heavy rain" with "torrential falls possible then easing overnight" it says. 

If you're heading out to do a final Christmas shop, it might pay to take an umbrella.
