Passenger Philip Wardale said that should be paramount, and the most logical was a basic texting solution.
The airline also said it would set up a team with specialist knowledge, which could be dispatched at short notice to affected locations to assist local teams.
"I don't know when the decision would be made, in our instance, to fly that team in," Mr Wardale said.
He also wanted better procedures between the airline and the engineering department, and said Air New Zealand should have considered flying in a replacement plane or transferred passengers to another airline.
Air New Zealand also said it would improve training for "disruption management" for all international airport management teams.
"I want to apologise again for the way our management of this situation let you down. While engineering disruptions are unfortunately a fact of life from time to time in the aviation industry, the situation should have been better managed on many levels and some valuable lessons have been learned," Mr Luxon said yesterday in a letter to passengers.
Hoped customers saw the actions outlined as an indication of how seriously the airline took the incident.
Compensation of $1000 was offered to each passenger for the disruption. additional reporting by Susan Strongman
