Firefighters have been called to Christchurch Airport after a cargo plane on the tarmac began billowing smoke from its undercarriage.

Fire and Emergency shift manager Lyn Crosson said crews responded shortly before 9am on Friday.

She said there was no fire on board the Boeing 737, and it was thought a fluid leak on to the plane’s brakes was responsible.

A spokesperson at Christchurch Airport confirmed no passengers were on board at the time.
