Queenstown police want to speak to a truck driver who picked up one of the occupant's of a car that crashed, leaving a young woman critically injured.
The crash, in Gorge Road, occurred early on 13 March and resulted in the Honda Odyssey being suspended upside down and pressed against the rear wall of the Gorge Road retail centre.
A 22-year-old German woman remained stuck in the car for several hours after it crashed, and remains in a critical but stable condition in Dunedin Hospital.
Detective Sergeant Brian Cameron said officers have spoken to one of the other occupants of the car.
"[He] has told police that after the crash he has been dazed but remembers walking back into Queenstown where he obtained a lift from the driver of a heavy motor vehicle - possibly a rubbish truck," Mr Cameron said.
"The truck took the occupant from near the ASB Bank on Camp Street in the CBD to the Arrowtown Junction, at the intersection with State Highway 6.
"We hope the driver of the truck will remember picking up this man - who is described as dark-skinned and aged in his mid-20s, who had suffered leg and head injuries in the crash."
This would have occurred sometime after 5am, Mr Cameron said.
Police want to speak to the truck driver of the truck and asking they contact Detective Matt Jones of the Queenstown Police on (03) 441-1600.
