Wild weather overnight has sent trees crashing down in Auckland, while many areas in the North Island copped a battering of rain and thunderstorms - with more rain to come today.
A large tree has fallen across a busy street in central Auckland, blocking two lanes outside the St Matthew-in-the-City church.
The 8-metre tree is blocking two lanes in Wellesley St heading towards Hobson St, Fire and Emergency NZ northern shift manager Colin Underdown said.
Firefighters were at the scene after being called at 6.32am.
Firefighters were working with chainsaws to cut the tree into smaller pieces to clear the area while awaiting a council arborist to assist.
There were no reports of damage to cars.
Elsewhere a power cut forced parents to keep their kids home after Riverhead School in northwest Auckland had no electricity.
The weather-related outage was reported at about 3.30am this morning.
Parents posted to social media saying they had been turned away at the gate this morning as the school had no power.
However power was restored just past 9am, and the school reopened.
A Vector spokesman said crews were investigating the cause of the outage, which was weather-related.
"Our objective is to do this as quickly as possible while ensuring the safety of our crews and the public."
All lines should be treated as live at all times, he said. If people saw damaged power equipment or power lines down they should keep a safe distance and call 0508 VECTOR, he said.
They could keep up to date with power restoration by searching for their address on the Vector website.
Two trees have also come crashing down in west Auckland. Police were alerted just after 5am, with the trees blocking the road at the intersection of Scenic Drive and Mountain Rd.
Strong gusts and heavy rains brought chaos to parts of Auckland late last night; bringing down trees and causing surface road flooding.
The MetService has issued severe heavy rain warnings for the western Bay of Plenty and Gisborne, north of Ruatōria and is in force until the early hours of tomorrow.
Those in the Gisborne area are being told to expect between 100 to 120mm of rain from the early hours of today through to 2am Thursday. Heavy rain accumulations of up to 120mm are on the cards for Bay of Plenty from Whakatāne westwards.
Locals are being told to keep a close eye on weather updates as heavy rain may cause streams and rivers to rise rapidly.
MetService says surface flooding and slips are also possible and driving conditions may be hazardous.
MetService meteorologist Philippa Murdoch said the gloomy weather was thanks to a complex low just to the northeast of New Zealand.
"That's spreading a number of fronts and troughs over the country today.
"With that, we are expecting and already experiencing a little bit of heavy rain - particularly in places exposed to that northeast like Northland, Coromandel, Bay of Plenty and northern Gisborne," she said.
"But most places are already seeing some rain or going to see some rain today - from the north down to through...Canterbury and Westland.''
Aucklanders can expect showers then rain from this evening and a significant temperature high of 19C. An overnight low of 13C is on the cards.
Wild weather hit Auckland last night, bringing down trees in Muriwai, west Auckland, and causing motorway flooding just after the Upper Harbour Highway on-ramp.
Wind gusts reached up to 65km/h on the Auckland Harbour Bridge and 110km/h in the Hauraki Gulf.
However, the northern and central fire communications offices both reported no weather-related call-outs overnight.
MetService said a band of thunderstorms had come through over the North Island - bringing bad weather and heavy rain particularly in Kaitaia in the early hours of this morning.
Auckland's heaviest rainfalls happened between midnight and 1am for most of city. Auckland Airport last night reported getting 12.8mm of rain from yesterday afternoon.
