Under the deal with the Australian Competition and Consumer Commission (ACCC), the airline was set to launch a plan worth up to A$20m (NZ$22m) to compensate affected passengers.
In a statement, Jetstar said its restart following the pandemic was a difficult time, for both travellers and airlines, and its communication and customer service “could have been better”.
“We sincerely apologise for letting customers down during this time,” a spokesperson said.
“We are encouraging anyone who feels they may not have received adequate compensation for a New Zealand flight disruption to contact us to have their case reviewed.”
It was unclear what had prompted the claim proposal or how many passengers it may affect.
Under the Civil Aviation Act, passengers have the right to either compensation or a refund if certain “engineering requirements or crew limitations” have disrupted scheduled flights.
“Where your domestic flight has been delayed or cancelled for reasons within Jetstar’s control, you may have rights under the Civil Aviation Act.
“Different laws apply to international travel.
“You may also have rights under consumer laws such as the Consumer Guarantees Act.”
The airline was extending an offer for a secondary claim to passengers who felt a previous request for reimbursement “was not handled correctly”.
Jetstar said the customers can claim for a review if their flight was disrupted prior to May 7, 2024.
