Fire crews rushed to Invercargill Airport this afternoon after reports of an issue with an Air New Zealand plane.
Fire and Emergency NZ said three appliances were sent about 4pm, but left shortly after.
Invercargill Airport general manager Nigel Finnerty said he had been told the aircraft was from Queenstown and had initially been diverted to Invercargill.
"We understood it was going to be diverted to Christchurch and that it was an ATR."
Mr Finnerty said he had been told the plane had encountered problems, but did not have any other information.
Air NZ external communications manager Anna Cross later confirmed it was one of the national carrier's planes.
"NZ5653 from Christchurch to Queenstown initially diverted to Invercargill due to an engineering issue," she said.
"However, the pilot has elected to return to Christchurch where engineering support is available.''
