A man has been arrested at Christchurch Airport after allegedly groping a female passenger on board a trans-Tasman Jetstar flight.
Police were called to the airport just after 2.30am today following a complaint that a man had sexually assaulted a woman on a flight from Australia.
The man was arrested upon arrival.
A Jetstar spokesperson said they became aware of the incident after a passenger complained to crew members about inappropriate behaviour from another passenger.
"The groups were separated for the remainder of the flight and support was provided."
