During that time Street led the media response for a number of significant events, including the loss of an A320 aircraft in Perpignan, France, 10 years ago.
''For the past six years Mark has driven the loyalty agenda, enabling the programme to grow to three million members and more than 60 retail and service partners,'' Air New Zealand chief revenue officer Cam Wallace said in a senior leadership team update.
When Street joined the loyalty programme it had 1.1 million members.
''Today our Airpoints programme is one of Air New Zealand's key competitive advantages, creating customer preference for the airline but also generating significant revenue in its own right,'' Wallace said.
The airline has more than 60 partners including bank, retail and travel firms covering a wide range of household and business spend categories including New World, Harvey Norman, Mercury, Mitre 10 and Z Energy.
''Throughout his career with us Mark has built strong, highly engaged teams who will no doubt be as sad as I am to see him go,'' said Wallace.
It is understood he will be leaving soon and a transition is underway.
