Jetstar say they're having issues with flights at Queenstown Airport due to the hot weather conditions.
A Jetstar spokesperson told 1 NEWS it's too hot, and the temperatures have been affecting the way the flight's navigation systems are calibrated.
"Jetstar’s Airbus A320 fleet uses a satellite-linked landing and navigation system known as Required Navigation Performance (RNP) for operations in Queenstown. RNP enables our aircraft to safely navigate the Queenstown terrain," the company told 1 NEWS in a statement.
"One of the limitations of RNP landings into Queenstown airport is that high temperatures can reduce the navigation accuracy. Today’s afternoon temperatures at Queenstown airport were above the RNP threshold."
A flight from Auckland was diverted to Dunedin, and the return flight was cancelled.
Air NZ reported no issues with its Queenstown flights.
