A highly agitated youth prisoner assaulted two staff members and broke a seat on a domestic transfer flight.
The incident happened about 6pm on Thursday on a flight from Nelson to Christchurch and involved a 16-year-old from youth prison Te Puna Wai, Fairfax reported.
The youth, accompanied by two staff, sat in a window seat at the rear of the plane.
An incident report obtained by Fairfax said the youth had a "significant history" of violence towards staff and gang links.
A female staff member sent a text massage just before they boarded the aircraft saying the youth was "quite anxious but settled" and that she had handcuffs "should things get out of control".
After the plane took off the youth grew more anxious, rocking and punching a seat, and saying he wanted to get off the aircraft.
