O’Rourke said he understood there was a head-on crash, and he co-ordinated the organisation of the rescue helicopter.
He understood there were seven people in the van and a sole occupant in the car.
“I don’t know really what happened; there are various reports, but I think obviously one of them was on the wrong side of the road, it was pretty much head to head.”
He said sun strike may have been a factor in the crash.
The Serious Crash Unit was advised and the road reopened at 10.30am, a police spokesman said.
A Hato Hone St John spokesperson said four ambulances, two rapid response vehicles and one helicopter were sent to the scene where eight people were assessed for injuries.
One was taken in a critical condition to Hawke’s Bay Hospital by helicopter.
One in a serious condition, three in a moderate condition and three in a minor condition were taken to Hawke’s Bay Hospital by ambulance.
A Fire and Emergency spokesperson said five fire appliances and a support vehicle had also been called.
