The first race of the ITM Auckland SuperSprint was stopped three laps in after a significant accident for Jason Bright.
Limited footage looks as if there was contact with Chris Pither at the back of the pack, pushing the Team BOC Commodore off the road and sliding into the wall at pit entry.
The car was blocking pit entry and was rescued by the recovery team. It is now being assessed by Brad Jones Racing.
Bright has walked away from the accident.
"We came out of the hairpin, Chris and I side by side, went up to that next kink under the bridge … not sure whether he got a little bit of kerb or what, but he got into my left rear, put me in the grass," Bright said.
"With wet grass, it made its way to the wall pretty quickly.
"It was a big hit, the angle of the wall I got was a bit bigger than another 10 feet further on."
The 2013 Jason Richards Memorial Trophy winner is unsure whether he'll race again this weekend.
"Depends what’s underneath, really," he said of the damage.
"He hit the right rear really hard, I’d be surprised if it hasn’t moved the whole back across – it felt like it. We’ll see when they get the back off."
Team boss Brad Jones said Bright's safety was the most important thing.
“The safety of driver is paramount – I’d say he’s got tipped and it looks pretty bad from here,” Jones said.
"Chris hasn't mentioned anything, we haven't seen anything," Super Black team boss Greg Hahn said. The #111 has just been handed a drive through penalty.
The race has resumed with Jamie Whincup in the lead.
