The 1943 de Havilland DH89 Dominie biplane known as Tui, pictured over Lake Te Anau, will be the star attraction at the reunion, which runs from April 7 to 9.
Dominies were the aircraft of choice for scenic, scheduled and charter flights work at Queenstown Airport from the mid-1950s until the early 1970s.
The eight-seater Tui was built for the Royal New Zealand Air Force and was the last of its type based in the resort.
Owned by the Croydon Aviation Trust near Gore, it has been restored for commercial operation, and will offer joyrides to the public for $75 a flight during the reunion.
Reunion organiser the Rev Dr Richard Waugh said more than 120 people from throughout New Zealand were scheduled to attend. They included former staff and family members from the original post-war airlines, Southern Scenic Air Services, Ritchie Air Services, West Coast Airways, Tourist Air Travel and the early Queenstown operations of Mount Cook Airline.
Weather permitting, Tui and four Cessnas operated by the early airlines will fly past over Frankton Presbyterian Church and central Queenstown on April 9.
