The news comes three days after Newstalk ZB reported a flight from Gisborne to Auckland was cancelled because of engineering problems.
A connecting flight from Auckland to Tauranga was also cancelled and Air New Zealand confirmed its Gisborne team organised a four-hour road service to make sure the customers got to their destination.
Last week, Air New Zealand announced interim earnings before taxation of $185 million for the first half of the 2024 financial year.
Net profit after taxation was $129 million.
A company NZX statement said passenger revenue of $3.1 billion was up 21 percent, driven by a significant ramp-up in capacity across the international network. Demand was stable in most markets but signs of softness in domestic corporate and Government demand was experienced from September.
Overall capacity was up 29 percent on the comparative six-month period.
Operating costs, including fuel, increased 21 percent due to a substantial increase in long-haul flying this year.
“Inflationary pressures also continue to be felt. Non-fuel operating costs have increased around 5 percent, or $100 million, due to price inflation, which is on top of an increase totalling 15 to 20 percent across the last four years.
“The cumulative effect of these increases is having a significant impact on the cost of providing air services, including on the domestic network, and the airline is currently reviewing fares and capacity to better reflect ongoing cost pressure.”
