Two people have been taken to hospital after a car rolled just north of Raetihi.
A police spokeswoman said a single vehicle with two people inside had overturned into a ditch between Valley Rd and Mangarewa Rd on State Highway 4.
Emergency services were called to the accident just after 8am on Sunday.
Both passengers sustained moderate injuries and were transported to Whanganui Hospital by St John ambulance.
A Fire and Emergency New Zealand spokesman said neither of the occupants were trapped in the vehicle.
