A long-running legal battle between rival Queenstown jet-boat companies has gone another round in court.
In a three-day High Court hearing in Queenstown that ended on Wednesday, the company behind KJet appealed an Environment Court decision in February to grant rival Thunder Jet consent to operate four boats on the lower Shotover River.
The decision broke KJet's monopoly on a stretch of the river from the Kawarau River confluence to Tucker Beach.
This week's hearing before Justice Gerald Nation continued a long-running battle between two Queenstown brothers behind the businesses.
Neville and Shaun Kelly have been fighting in court since 2008 over the former's company, Thunder Jet, wanting to operate in competition with the latter's KJet.
