Motorists are being urged to take care on Northland's roads after a spate of serious crashes at the weekend.
All were single-vehicle incidents in which the driver lost control, in one case with near-fatal consequences.
The worst occurred about 1.50am on Saturday on State Highway 10, near the intersection with Otangaroa Rd north of Kaeo.
Senior Sergeant Peter Robinson of Kerikeri police, said the car was heading south with six occupants when it crossed on to the wrong side of the road and rolled. Most were understood to have been thrown from the vehicle.
Two passengers were flown to Whangarei Hospital by the Northland Electricity Rescue Helicopter in a serious condition. The others sustained moderate injuries and were taken to Kaitaia by St John Ambulance.
