Two people have been badly injured in a crash on State Highway 2 north of Tauranga.
A St John spokesman said two people with serious injuries had been taken to Tauranga Hospital by ambulance.
Police responded to reports of a serious crash on the highway in Minden in the Western Bay of Plenty at 2.30pm.
Police initially said a truck and car had collided but have since said this was incorrect.
"Police can now confirm that a single car has crashed into a tree and its two occupants are in a serious condition."
