Many Aucklanders are facing a morning without power as wild winds and rain cause havoc across the region this morning.
Fallen trees have damaged houses and cars and brought down power lines - cutting power to dozens of areas across Auckland.
Motorists face widespread disruption and are being warned to expect delays, with lower speed limits imposed on the harbour bridge as wind gusts hit 110km/h.
Around 30 shipping containers have been blown over in south Auckland, a witness says.

Vector is warning the public to stay away from an area in Albany, due to two high voltage power lines brought down in the bad weather.
The roads affected are Clemos Lane and Jack Hinton Drive.
"The roads have been closed for safety and work is underway with traffic agencies to undertake repairs," a statement released at 8.31am said.
After yesterday's weather warning for the region, crews were scaled up to respond to outgages, Vector's Marko Simunac said.
Vector couldn't say how many outages crews were still responding to at 8am.
"Given the weather forecast for today, we may need to stand our crews down for their own safety if the wind picks up again," Simunac said.
Members of the public are being asked to "please bear with our crews" if an outage happens in their area.
Counties Power says the network on the western side of the Franklin and Papakura region is severely impacted by the extreme weather.
"There will be long resolution times as crews work as safely as they can out there in these high winds across many outages. Please prepare for a morning without power."

Fire crews have been called out to over 100 weather-related incidents since the storm began at 3am.
Northern fire communications shift manager Paul Radden said most of the calls have been due to powerlines and trees coming down and roofs lifted.

Firefighters were also called to a house fire in New Lynn, West Auckland, he said.
A SkyCity spokeswoman said their rigging team had been out early this morning to check for any potential damage to the Sky Tower. However, no damage was found.
"Thank goodness," she said.
The Sky Tower has been designed to withstand storms and winds gusting up to 200km/h, which can result in a sway at the top of the concrete shaft of about one metre, its website reads.

Train and ferry services disrupted
Commuters are told to expect delays and cancellations this morning.
Road authorities said response crews were responding to multiple incidents relating to fallen trees and power outages affecting traffic signals.
Train users are facing disruptions with the Onehunga train line suspended as a result of overhead line issues near Penrose.
The line issues are also affecting southern line services from Papakura to Britomart which will now travel via Newmarket.
Just after 7am, Auckland Transport said all southern line train services are now suspended due to another overhead line issue at Ōtāhuhu.
Earlier this morning, the service between Papakura and Britomart had been detouring the area, but they are now cancelled.
One lane in each direction is now open on Pakuranga Road heading towards Panmure Bridge as contractors clear a tree that was earlier blocking the road.
Ferry commuters are also heavily affected this morning.
Auckland Transport says all Northcote Point services are cancelled until further notice due to weather conditions.
The 7.35am ferry service between Auckland to Birkenhead and the 7.55am service between Birkenhead to Auckland have been cancelled due to a mechanical issue. The Waiheke to Auckland ferry has also been delayed by 10 minutes this morning due to a vessel breakdown.
Lines company Vector is responding to outages in Whangaparāoa Peninsula, Torbay, Milford, Birkenhead, Pāremoremo and Murrays Bay in the north.
Much of Dairy Flat and Helensville, northwest of the city, are also in the dark.
Further north, a lot of Mahurangi is without power.
The Vector website shows most of Te Atatū Peninsula, in west Auckland is without power.
A witness told the Herald he spotted powerlines arcing in Te Atatū and debris from fallen trees in and around Te Atatū Peninsula.
He described the difficulty of driving down the Northwestern Motorway about 4am, saying: "I was driving straight and I could just feel the car being pushed."
Other parts of west Auckland badly affected are Massey West, Whenuapai West, Waimauku, Oratia, Laingholm, Titirangi, Huapai and Kumeu.
There are also power cuts in parts of Westmere, Henderson and Mt Wellington.
In the south, there are outages in parts of Ōtāhuhu and Māngere East.
And out east, there appear to be outages in Bucklands Beach, Shamrock Park, Maraetai, and the area south of Beachlands.
Vector says for safety, people should stay well away from downed lines, consider them live, and call 111.
It says it has response teams, including specialist arborists, responding to outages throughout the night, but they may stop work if conditions become dangerous.
Vector says anyone who loses power should report through Vector's website.
