A teenage boy has been taken to hospital with back injuries after a jetboat hit a rock in the Shotover River in Queenstown.
Fourteen people were onboard the boat when it hit the rock at the entrance to the second canyon at around 4:30pm.
Emergency services say a teenage boy was flown to Queenstown Hospital with back injuries. He is in a moderate condition.
Five passengers, all tourists, were taken to hospital with minor injuries.
Shotover Jet General Manager Clark Scott says the company's immediate focus is on the wellbeing of its customers and staff.
"Our staff are at the hospital supporting the customers, their families and friends and that's our main priority at this moment in time," says Mr Scott.
Queenstown Lakes District Harbourmaster Marty Black has been on site to inspect the boat. Maritime New Zealand has also been informed.
Shotover Jet says they anticipate operations will resume tomorrow.
