Air New Zealand (NZE:AIR, ASX:AIZ) said Friday it has completed the trial of a new digital identity technology designed to reduce repeated passport checks and make travel more seamless.

The company said in a statement that the technology allows customers to add their passport information in the Air NZ app, securely share verified identity information during online check-in, and use it to support biometric verification at selected touchpoints across the journey.

The trial also included integration with the New Zealand Traveller Declaration, making it easier for customers to complete the online form, with Air New Zealand working closely with government agencies and industry partners to develop the technology further.

The airline said it is sharing insights from the trial with global aviation bodies, including the International Air Transport Association.

The company's Kiwi shares fell 1% in recent Friday trade, while its Australian shares were down nearly 3%.
