The wild weather also stretched volunteer fire brigades with Kerikeri and Rawene particularly busy dealing with flooded homes, downed trees, blocked drains and crashes.
The weather also wreaked travel havoc in Auckland, including leaving commuters stranded after trains reportedly stopped on the tracks around Glen Innes.

Crews are unable to restore power in Kawakawa Bay which is inaccessible due to flooding.

Crews and storm management teams are on standby.
Vector has reminded people to stay away from damaged electrical equipment and report issues via their phone line 0508 Vector.

Northland Civil Defence Emergency Management (CDEM) Group spokeswoman Victoria Randall said the latest rainfall figures provided by Northland Regional Council showed that up to 210mm of rain had fallen in the upper Waitangi River near Lake Omapere since 6am on Tuesday.
The figures also showed 208mm of rain had fallen in the eastern hills above Kaeo, 189mm near Houhora and in the eastern hills above Ngunguru, since Tuesday.
River and stream levels in the region are being monitored closely, with special attention being paid to the Kaeo, Waitangi, Whakapara and Mangakahia rivers. There are risks of flash flooding in some areas caused by heavy, localised thunderstorms.
There has already been flooding on State Highway 10 at the bottom of the Bulls Gorge south of Kerikeri, causing hundreds of vehicles to back up in either direction around 3pm today. A single police officer attempted to control the chaos.
Randall said it is very likely that State Highway 10 just north-east of Kaeo would flood with last night's high tide about 7pm.
"Conditions are still fairly hazardous for driving and people need to be aware of the possibility of surface and localised flooding so please take care, only travel if necessary and keep informed before you leave.
"There are number of ways you can do this including options such as the AA Roadwatch website, local radio or social media."
Civil Defence was also warning farmers to move stock to higher ground if they have any concerns.

The top half of the North Island is seeing a number of faults across the Chorus network.
In Whangamata, the core fibre damaged in a slip on Wednesday has been repaired, restoring broadband and voice services to customers of all but one of the Chorus roadside cabinets in the area. Work is under way to repair a secondary fibre that will restore broadband and voice services to customers served by the final street cabinet. That is expected to be completed today.
In a statement issued yesterday afternoon, Chorus apologised to customers who may have lost phone or internet services, with the company saying it was working with its service companies in the regions to safely restore services.
Thames-Coromandel District Council alerted people to a number of road closures.
The Whangamata bypass, SH25 Harry Watt Rd to Port Rd, is closed in both directions while Whangamata's Avalon Rd is also closed due to slips. Contractors are trying to clear the situation.
The Kauaeranga Valley Rd is closed from the Kauaeranga Visitor centre upwards. All camping, hut and walking tracks are inaccessible.
"We're also doing some urgent repairs to a pipe which supplies water to Whangamata," Civil Defence controller Garry Towler said.
"This is our priority at the moment as the pipe has moved due to subsidence from the flooding over the past few days. We've got earthmoving machines in stabilising the pipe and this will take the afternoon to fix. We have a back-up supply, so people don't need to worry about their water supply."
The Kerikeri fire brigade was called out four times in less than half an hour on Thursday, starting at 12.35pm when rainwater brought down part of the ceiling in a Kemp Rd home. All four calls were weather related.
One of the worst-hit businesses was the Soundlounge in Kerikeri, Northland's only independent record store, where on Thursday afternoon water from an overflowing gutter entered the ceiling cavity and gushed into the shop, damaging thousands of dollars' worth of stock.
The heavy rain forced the cancellation of the first day of the biennial Te Ahuareka o Ngati Hine Festival yesterday, which normally brings thousands of people to Otiria Marae near Moerewa.
A concert last night featuring Fat 32, Huaki Puanaki, Ruia Aperahama, Russell Harrison and Troy Kingi was going ahead as planned, however. Organisers are due to make a decision about day two of the festival, which celebrates everything related to the Ngati Hine iwi, first thing today.
