A Queenstown paragliding company has no idea how one of its flights ended in a crash, leaving one person with moderate injuries and another with minor injuries.
It has also temporarily suspended its commercial operations.
The accident happened around 11am after a pilot and passenger from Skytrek Tandem Hang Gliding and Paragliding took off from Coronet Peak.
The company said in a statement they landed on a slope on a side of the mountain, approximately half-way to their intended landing point at Flight Park near Speargrass Flat.
"Weather conditions were described as 'stable' at the time of the incident, and at this early stage there is no indication as to why it happened," the statement reads.
"The Civil Aviation Authority has been informed and the company is cooperating fully with relevant authorities and local police."
A rescue helicopter remains on standby while the pair are assessed. The full extent of their injuries has not been revealed.
The company refused interview requests and instead referred to the statement.
