Air New Zealand has suspended flights to Tahiti and Noumea until June 30.
The route cancellations are related to new Government restrictions to try to stop the spread of Covid-19 in New Caledonia and French Polynesia.
The airline also made a change to its refund policy and now allows anyone with an international or domestic booking between March 20 and May 31 to cancel their flight and receive credit for the full cost of an unused ticket.
The credit will be valid for 12 months and can be redeemed against any flight, with customers paying any fare difference.
The airline has also recently announced it will reduce capacity by 80 to 85 per cent on its international flights from March 30, until June 30.
