Nine people were injured when a car apparently made a main highway U-turn in front of a rental van near Reporoa, south of Rotorua.
Police are still looking for the car's driver, who left the scene before they arrived.
They said the crash this afternoon was caused by a combination of alcohol and speed.
Emergency services from Taupo, Reporoa and Rotorua were called just after 5pm to State Highway 5 in Reporoa to the collision between a car and a van.
When The Daily Post arrived at the scene, a black Nissan Skyline was in the middle of the road with the driver's door caved in.
