A tornado-like waterspout has ripped through central Auckland's waterfront, toppling at least one shipping container and wreaking havoc on yachts, ships and cars.
Vehicles were swept into the ocean and a yacht was struck by lightning as the storm left a trail of destruction on Monday night.
A shipping container toppled on to a car at Jellicoe Wharf near Tinley St, trapping the driver. They were tended to by emergency services and taken to hospital in a moderate condition.
Several yachts at Westhaven Marina lost their moorings and a catamaran was overturned in the turmoil.
Coastguard duty officer Hemi Manaena said the winds had caused "significant damage" to a large number of recreactional vessels at Westhaven.
The Sealink Ferry also lost its mooring at Wynyard Quarter and needed to be retrieved.
"We'd like to reiterate that there's a large amount of debris in the harbour," said Manaena.
"Mariners should remain vigilant when navigating the area, especially around the Princes/ Hobson Wharf area - a shipping container has fallen into the water there."
There were reports of other containers floating in the harbour and a car had also gone into the water near the entrance to the Viaduct. Other cars were being retrieved by a tow truck.
Tornado 'sucking up all the plants'
Road cleaner Fine Kaufusi, 40, was on the graveyard shift when it started to rain heavily late last night.
"It was around 10 o'clock. I was in my buggy on the other side. I was about to start my work when it started to rain, so I waited.
"All of a sudden I saw like a light and then a tornado - it was sucking all the plants and branches into it.
"Lucky I didn't come over here with my buggy because that would've been me sucked up."
Kaufusi, of Otara, said after the tornado had passed, he and his co-workers came out to survey the damage.
"There were branches everywhere and the [construction] fences were down.
"My mate came with the compactor and just cleaned it all up.
"I'm still cleaning - still some leaves left," he laughed.
'Too scared to open door'
A witness described seeing a tornado rip through lower Queen St and said she was too scared to open her door. Other reports suggested it was a waterspout.
"It could be severe gusts from the thunderstorm which happens when it collapses and all the air rushing out, it can be strong enough to blow containers over.
"There definitely was some strong winds recorded around Auckland's harbour bridge at the time.
"Temperatures dropped two or three degrees in a short time which is always a good indicator but we can't confirm it was a tornado at this stage."
Earlier the MetService issued a severe thunderstorm watch for Taranaki to Northland until midnight tonight.
It followed a wild 24 hours of weather, which saw the roofs of homes blown off in St Heliers, a house hit by lightning in West Auckland, The Cloud on Auckland's waterfront ripped to shreds and a tornado rip through properties in Taranaki.
