Air New Zealand is removing its straight to gate check-in process for domestic flights.
From July 1, all passengers, including those without checked baggage, will have to check-in through the Air New Zealand app or at a kiosk.
Previously passengers travelling without checked baggage were able to go straight to a boarding gate and check-in there by scanning their mobile app on boarding.
The airline said in an email to customers that checking in customers that way has meant "our teams haven't always been able to complete all necessary final pre-departure procedures on time."
Air New Zealand said check-in completion time for domestic flights is 30 minutes prior to departure. Customers not checked in before that time will be unable to travel.
However, online check-in continues to be available for all customers from 24 hours prior to departure.
