Three people, two in a serious condition, were airlifted to Waikato Hospital following a single-vehicle crash on State Highway 1 at Waiouru.
A police spokesman said they responded to a single-vehicle crash at the intersection of SH1 and Paradise Valley Rd about 1.15am on Sunday.
Fire and Emergency New Zealand spokeswoman Alison Munn said a vehicle had rolled off the road.
“Nobody was trapped.”
Fire crews from Waiouru, Tūrangi and Ohakune responded and set up a helicopter landing zone.
