Air NZ has started trialing its new in-flight WiFi service on one of its long- haul Boeing 777-300 planes.

Air NZ chief digital officer Avi Golan says they will gather customer feedback to ensure it meets the needs of customers before it's rolled out across their international jet fleet.

In-flight WiFi will be installed in their Boeing 777-300 fleet by June, and will be rolled out to the Boeing 777-200 fleet by April.

"The trial will not only test the technical aspects of the service, it will also gather feedback on pricing options," Mr Golan said.
