The temporary shut-down of Refining New Zealand's pipeline into Auckland is impacting all airlines operating into and out of Auckland Airport and limiting the volume of jet fuel able to be uplifted.
"However, closer inspection after excavating the pipeline has shown that the damaged section needs to be replaced".
While motorists aren't affected at this stage, the government has deployed a naval tanker to help with fuel distribution after opposition parties claimed there had been a failure to secure supply to the nation's busiest airport.
The temporary shut-down to restore the fuel supply and fix the damaged the pipeline could potentially disrupt travel for the next 10 to 14 days, according to the New Zealand government.
Marsden Point owner Refining NZ spokesman Greg McNeill told the New Zealand Herald the issue began on Thursday, when a leak was spotted in the pipeline that supplies aviation fuel from Marsden Point to Wiri, near the airport.
About two dozen domestic and worldwide flights out of Auckland have have been cancelled in the past 24 hours because of a jet fuel shortage. "Our team is now preparing for this work". The contaminated soil has been removed, the refinery said.
Jetstar, Qantas and Virgin Australia were also advising their passengers to expect disruptions to flights into and out of Auckland, with some services taking in refuelling stops in either Wellington or Christchurch.
"We will have additional staff in the terminals supporting passengers and addressing any questions or concerns they may have", he said in a statement.
Chief executive Adrian Littlewood said the airport was working closely with airlines and others, trying to focus on helping passengers.
BARNZ represents 28 global airlines flying into and out of New Zealand.
Still, the transport fuels company said fuel supplies nationally were healthy and that the disruption won't "materially impact company performance".
"BARA has long argued that supply chain constraints and lack of effective competition among jet fuel suppliers stymie industry performance and will impede ongoing growth".
