The BBC's Castaway actors and crew on Great Barrier Island were among those to suffer from yesterday's heavy rain.
While most of the serious damage occurred in Northland, the heavy rain and strong winds affected most of the North Island - from the Maadi Cup rowing regatta at
Lake Karapiro to Great Barrier.
Coromandel and Bay of Plenty residents were braced for floods overnight as the storm which lashed Northland and Auckland headed east.
But MetService said today that heavy rain had now finished for Auckland and the Nelson Ranges and was easing in the Coromandel Peninsula. It should ease during the day in Bay of Plenty and this evening for northern Gisborne.
Heavy rain warnings remained in place for the Bay of Plenty and in Gisborne, north of Ruatoria, but had been lifted for Auckland and the Coromandel Peninsula.
Weather-related incidents from around the upper North Island included:
Great Barrier Island
The weather left Great Barrier Island cut off from transport to the mainland yesterday with no flights or boats in or out.
The weather was expected to make life particularly miserable for the Castaway cast and crew filming on the island.
Fiona Green, who runs a car rental company, said the rain would be blowing right into the site at Harataonga.
"It will come in like a funnel and they will be swimming in mud. The conditions will be rotten."
The film crew were having to use four-wheel-drives to get in and out of Harataonga because of the weather.
South Auckland/Waikato
Bad weather forced the abandonment of Maadi Cup rowing races at Lake Karapiro, where nearly 2000 students from 106 schools are competing.
Conditions on the lake were considered too dangerous for students, although the schedule fell behind by only six events.
Domestic rowing manager Kevin Strickland said events were "canned" at 4pm, when it became clear the weather would not improve.
Waikato-Bay of Plenty Fire Service Assistant Commander Roy Breeze said firefighters were on standby in Silverdale, north of Auckland, for emergency work that was expected to be needed overnight in Auckland and Northland.
He reported no major incidents in the Waikato and Bay of Plenty late yesterday.
Coromandel
Regional council Environment Waikato's flood duty officers were closely monitoring the rainfall in flood-prone Coromandel last night.
Spokesman Brendan Morris said more than 180mm of rain had been recorded at the Pinnacles in 24 hours yesterday and a further 200mm was forecast to fall today.
"There's also been a further 120mm at Castle Rock. The risk on the Coromandel varies. In terms of the flash-flood risk it's the West Coast communities that are in most danger. On the East Coast it's more of a risk over access, especially in areas around Hikuai [Pauanui and Tairua] and Whitianga, where the state highway is."
Tairua fire chief Chris New said no flood-related incidents had been reported in the area.
Emergency services in Rotorua, Tauranga, and Whitianga said that while the weather was bad, no damage or incidents had been reported.
