Air New Zealand is restricting ticket sales as airline services continue to be disrupted by a rupture to a pipeline carrying jet fuel to Auckland Airport.
Having cancelled 30 domestic and trans-Tasman flights since Sunday, Air NZ says there will be more cancellations on Wednesday.
These include five Australian services, two Fiji services and a return service to Ho Chi Minh City in Vietnam.
Air NZ says the unusual step of restricting ticket sales is to reduce pressure on the network and ensure customers already booked can be re-accommodated with minimum disruption.
"This includes stopping all sales on some selected international services," it said.
The damage to the pipeline, which connects the Marden Point refinery in Northland to the airport via Wiri, was discovered last Thursday.
The pipeline has been shut down temporarily, restricting all airlines to 30 per cent of their normal jet fuel usage.
Refining NZ says repairs are on track to resume deliveries to its Wiri storage depot between Sunday and Tuesday.
Andrew McNaught, spokesman for Refining NZ's fuel customers, says the supply into Auckland by road continues to be healthy.
He says there is no shortage of petrol or diesel in and around Auckland.
The refinery is continuing to produce fuel and two dedicated coastal shipping vessels are continuing to load at the refinery for distribution around the country's ports.
