Richard Benton has privately owned the International Antarctic Centre for the past 11 years and has been the driving force behind much of its innovation.
However, the centre, which opened on September 28, 1990, has faced tough trading conditions since the February 22 earthquake.
Benton said: "The timing is now right to pass on the reins to the airport company for the next very exciting stage of the attraction's development.
"It has been a real privilege and honour to lead a team that has developed a very successful tourism facility and to have been part of the Christchurch Antarctic community."
Boult says the acquisition is in line with the company's strategic plan to increase non-aeronautical revenues and profit.
Some of this will be achieved through the acquisition and development of complementary or closely aligned businesses.
Other company initiatives are the continuing development of Dakota Park freight and logistics precinct and Spitfire Square, a new retail development which has recently gained consent.
The airport, which is owned 75 per cent by Christchurch City Holdings Ltd and 25 per cent by the Government, will take over ownership of the International Antarctic Centre on December 1, with the attraction's staff offered continuing employment.
