A female Chinese tourist is dead after a jetboat crash in Queenstown. The body of a woman has been recovered after the jetboat she was in flipped on the Shotover River, trapping her under the boat.

The woman died after the accident at the confluence of the Kawarau and Shotover Rivers, in Queenstown this afternoon when a Chinese tour group were on the jet boat ride.

Five other people were being treated at Lakes District Hospital, at Frankton, Queenstown.

The incident happened when the Kawarau Jet boat overturned after hitting a sandbar about 2.45pm.
