Jobs of Virgin Australia managers in New Zealand are under threat as the airline assesses whether it will shift the roles to Australia.
Virgin's management in this country is based in Christchurch and it is believed up to 40 staff could be affected.
The airline's pilots and cabin crew based here would not be affected.
"We are currently reviewing a proposal to integrate the management of Virgin Australia New Zealand's operations into the rest of our international operations, which would see one team manage all of our international operations out of Brisbane, Australia," a spokeswoman said.
The airline said proposal would create a single line of accountability, improving coordination of our international operations and reducing duplication.
