Air New Zealand will be putting its Auckland to Hobart and Auckland to Seoul services on hold from April, as the airline scrambles to make schedule changes in response to maintenance issues with certain engines.
Engine manufacturer Pratt & Whitney disclosed earlier this year that it has a problem with its Geared Turbo-Fan engines.
While it does not affect the engines' safety, it does require a revised maintenance plan.
The new plan means Air New Zealand could have as many as four aircraft grounded at a time - impacting schedules.
Chief executive Greg Foran spoke to Corin Dann.
