Auckland Airport has installed new scanning equipment that increases international departures processing capacity five-fold.
Twelve new automated pre-security gates scan boarding passes to grant passengers to security areas rather than have them checked manually.
The new equipment is part of a move to more automation at the international terminal where up to 7000 people can be processed every hour.
Auckland Airport's general manager of operations Anna Cassels-Brown said the technology transformation that could eventually include biometric authentication to enable seamless journeys from check-in to boarding the aircraft.
"Where possible we see automation as a key way to improve the airport system by being more accurate, reliable and faster.''
