Five people have been taken to hospital after a serious crash east of Auckland.
Two cars collided on Whitford-Maraetai Rd at 11:30 on Friday.
Three people were trapped in one car after it rolled, with one person suffering serious injuries.
The other two passengers were taken to Middlemore Hospital in a moderate condition.
Two people in the other car also received minor injuries.
A police spokeswoman says the road was covered in oil after the crash and one car was blocking both lanes.
It was cleaned up overnight and the road has now reopened.
