Air New Zealand said it believed the fuel pipeline rupture that is preventing jet fuel from being piped from Refining NZ's plant at Marsden Point to Auckland would not have a big impact on its bottom line.
A spokeswoman for the airline said there had been no change to its statement issued on Monday, which said the supply issue was unlikely to have a material impact on the annual result for the June 2018 year.
The company last month reported earnings before tax for the 2017 financial year of $527 million - the second highest result in the airline's history.
In its latest update, Air NZ said it was continuing to experience disruption to its services following the temporary shut-down of Refining NZ's pipeline to Auckland.
The airline cancelled four transtasman and 26 domestic flights between Sunday and today.
