A truck has ploughed into a Porsche dealership, injuring two people and damaging several luxury cars in the Auckland suburb of Newmarket.

Emergency services were called to the crash involving at least six vehicles at the Porsche showroom on Great South Road at about 11:30am.

Inspector Lou Alofa said the driver of a truck and trailer unit had lost control and hit five parked cars outside the showroom.

St John's ambulance spokesman James Ihimaera said one person was taken to hospital with serious injuries.


Another person with moderate injuries had to be freed from their vehicle by the Fire Service, Mr Ihimaera said.

Local worker Paul Scotting said the scene was "like a plane crash".

He said it appeared the fully laden truck and trailer had hit a van doing a U-turn on the busy arterial road.

The truck and trailer then lost control and smashed into another truck unloading a Porsche at the luxury car dealership, Mr Scotting said.

That Porsche had then tipped off the truck into another car at the yard, he said.

"It's carnage," he said.

Mr Scotting said the van involved in the initial collision had been shunted across the road into the side of a parked BMW.

Two more cars, including another BMW, had also been damaged in the aftermath of that collision, he said.


About 10 police cars along with four fire engines and multiple ambulances attended the scene.

Hundreds of people gathered near the Porsche dealership.

The crash caused major traffic delays.
