Dashcam footage has captured the horrific accident that involved a car and truck on Auckland's Southern Motorway last weekend.
On Saturday at 11.16am, a car and truck collision closed at least two northbound lanes near the Mountain Rd overbridge, causing major delays on the motorway.
An off-duty paramedic on the scene had told police injuries to those involved were minor.
An Auckland driver, Tony Ha, managed to film the horror scenes that unfolded on a DriverCam dashcam that he only finished installing that morning.
The out-of-control car then swerves back into the other lanes of the motorway, nearly hitting other motor vehicles.
The video shows a big chunk of the back of the car taken out, and the truck crashing into the barrier.
Ha told the Herald he didn't see the accident but heard a "loud bang" before looking at the horrific aftermath in his rear-view mirror.
He then pulled over and waited until it was safe to cross the motorway and talk to the truck driver.
"The motorway was still moving and there were a couple of people a little bit closer like the first responders," he said
"Afterwards I crossed the motorway and had a chat to the truck driver and his passenger.
"The driver was a bit shaken up, he was okay [but] he was more worried about his delivery then he was about anything else."
Speaking about the aftermath, Ha said he was surprised that nobody in the Mazda had died but reassured the Herald that everyone was okay.
"It was pretty chaotic and a big mess," he said.
"If you have a look at the pictures of the Mazda, if the rear passenger was on the right, he would have been crushed. He was very lucky, he looked like he came out of it unscathed."
