The cause of a sudden loss of cabin pressure aboard a domestic flight last year, forcing 76 passengers to don oxygen masks, may not be known for several months.
Air New Zealand flight 414 had left Wellington bound for Auckland when it encountered a problem while descending over Raglan on
August 30.
The pilot was praised for his quick action in bringing the Boeing 737-300 down from 33,000 feet to around 7000 feet, where cabin crew told passengers they could take off their masks.
The aircraft landed at Auckland without further incident, and Transport Accident Investigation Commission (TAIC) experts immediately launched an inquiry.
Seven months on, the investigation is ongoing, a spokesman for TAIC confirmed.
