One person is dead and another is being flown to hospital after they were crushed by a truck in the Queenstown area.
Police were notified just before 4pm to reports of the incident near Closeburn.
A crane assisted in moving the vehicle and a helicopter has transported the trapped person from the remote location to Dunedin Hospital in a critical condition.
Queenstown photographer James Allan was at the scene. He said two people had been crushed by a sewage truck. He said one was trapped for two-and-a-half hours.
"The truck was going in there to do something and it has rolled back into a structure of some sort. One person is killed and one person was trapped at the waist."
