Fiji's Nadi airport is being used as a stopover to refuel longhaul flights from New Zealand to the United States as a ruptured pipeline is causing fuel shortages at Auckland airport.
Air New Zealand said it had diverted several flights to Fiji over the past few days to top up on fuel.
It said the temporary shut-down of the damaged pipeline was affecting all airlines operating in and out of Auckland Airport.
The airport said it does not know how long the problem would take to fix, but it said it was in regular contact with the company responsible for the pipeline, Refinery New Zealand, to know when it would be operational again.
Travellers were being advised to check with their airline for any disruptions to flights or on Auckland Airport's website.
