Three separate investigations have been launched into yesterday's jetboat crash on the Shotover River.
Five people - including the driver - were air-lifted to Lakes Hospital, where one still remains this morning.
Two experts from the Transport Accident Investigation Commission are heading to Queenstown.
The company - KJet - has also launched its own internal investigation.
