An Air New Zealand passenger who was left stranded in Hawaii last week says he is surprised the airline hasn't made more recommendations, after an investigation into the incident.
The Boeing 767's pilots aborted takeoff on July 27 left 227 passengers stranded in Honolulu for up to 56 hours.
An investigation by the national carrier has found the root cause of the disruption was an engineering issue which had previously been identified as a faulty warning light on a Boeing 767.
The airline was also continuing another inquiry into claims that pilots and cabin crew in Honolulu had been drinking and would not have been available for duty at one point, even if the aircraft had been airworthy.
Following the initial investigation into the stranding, Air New Zealand chief executive Christopher Luxon said the airline would invest in a new communication system to provide better contact with affected passengers.
