Air New Zealand chief executive Christopher Luxon will step down from that post on 25 September, after which he will move to an advisory role with the airline.
He resigned on 19 June, and chairman Tony Carter says a search for a replacement chief executive has started.
After 25 September, Carter says that Luxon will "move to advising and supporting the incoming Chairman and new CEO so we have a seamless transition and are set up well for further success."
Luxon says he is thrilled at having been able to lead the company for the past seven years.
"However, I do feel it is the right time for a new leader to take over and preserve and enhance the good things from our past, but also to put their own stamp on the organisation bringing their own personality and emphasis to the role as I did," he adds.
Luxon has been credited with helping to turn the airline into a more customer-focused brand, and for reinforcing its Pacific Rim-focused network strategy.
He joined the Star Alliance carrier in May 2011 from Unilever North America, initially taking up the role of group general manager international airline, before succeeding Rob Fyfe from the start of 2013.
