Queenstown Airport safety and operations general manager Mike Clay said that three of the five flights occurred soon after the imposition of level 4 lockdown last March.
No direct repatriation flights carrying New Zealanders home from abroad have landed in the resort.
The airport worked with border agencies, the Southern District Health Board and Queenstown Corporate Jet Services (QCJS) to ensure Covid-19 health and safety protocols were followed, he said.
QCJS manager Vickie Hill said "client and business confidentiality" meant she could not reveal the passenger's identity or nationality.
"From time to time, during the current climate, we get requests for people to return to locations outside New Zealand."
A special application had to be made for the flight, including getting approval from the New Zealand and Australian governments, but no one officially entered the country as the airport's tarmac was considered international airspace.
The pilot, passenger and ground staff were wearing personal protective equipment (PPE) and maintained at least 4m distance from each other, Hill said.
Southern DHB regulatory and protection team leader Susan Moore said its role was to check appropriate procedures for disembarking, physical distancing and PPE were followed, and was satisfied that had been the case.
The pilot got out of the plane for a pre-flight inspection and refuelling of the aircraft, but had no physical interaction with anyone before getting back on board, Moore said.
