Two people have died and three are in a serious condition after a serious crash on SH16 near Woodhill.
The crash happened between Restal and Kiwitahi Rds near Woodhill School shortly before 5pm.
St John said the three seriously injured patients were taken to Auckland City Hospital.
Waitemata Senior Sergeant Jesse Mowat said a northbound driver lost control of his vehicle. "The driver appears to have drifted into the southbound lane where his vehicle has clipped a van. As a result the driver of the Nissan has veered further into the southbound lane and has effectively had a head-on collision with another vehicle heading south."
The Nissan caught fire, he said, and two people in the car died.
e Police are investigating the cause of the crash but the road was wet and it was raining at the time, Mowat said.
