Air New Zealand chief financial officer Rob McDonald will retire at the end of the year and will be succeeded by group general manager of corporate finance, Jeff McDowall.
McDonald has been with the airline for the past 24 years.
Chief executive Christopher Luxon said McDonald signalled his intention to take up non-executive appointments from 2018 almost two years ago which allowed the airline to put in place a succession planning process.
McDonald became group financial planning manager at Air New Zealand in 1993 and was appointed group treasurer in 1995 before being appointed CFO in 2004.
Luxon said McDonald had played an integral role in helping to expand Air New Zealand's network and was one of the architects behind its successful fleet simplification strategy that has delivered improved cabins and lower operating costs.
