Charges have been laid against two commercial jet-boat drivers after a crash between their boats in January on the Dart River near Queenstown.
One passenger's collarbone was broken and other passengers were bruised.
Both jet boats were from Dart River Safaris, with one heading upstream with 11 passengers and the other heading downstream, containing only the driver.
The charges, laid under section 65 of the Maritime Transport Act, were that the drivers caused unnecessary risk or danger to those onboard through their actions.
If convicted, the drivers could face up to 12 months' jail and/or a fine of up to $10,000.
After the accident, Maritime New Zealand imposed conditions on the company, preventing the drivers from operating.
The matter will be dealt with on July 29 at the Queenstown District Court.
