Emergency services on standby following incident onboard Air New Zealand flight landing in Christchurch

Emergency services were on standby at Christchurch Airport on Thursday morning after reports of an incident onboard an inbound aircraft.

There are scant details available about the incident which took place just before 8am.

Fire and Emergency NZ confirmed they were called to the airport at 7:45am after reports of smoke in the cockpit of an inbound aircraft.

Police told Newshub they received reports of an "airplane in distress", but it has since landed without incident.

It's understood the aircraft involved was an ATR, an aircraft type used by Air New Zealand on regional routes.

A spokesperson for Air NZ said there was a “a momentary haze observed in the flight deck” onboard Flight NZ8761 from New Plymouth to Christchurch.

As is procedure, the flight was met with emergency services on arrival into Christchurch.  

The flight landed safely at its intended location, and customers disembarked normally into the terminal.

By the time it landed safely at 7.58am, the smoke is said to have cleared. A FENZ spokesperson says their crews arrived at the airport but didn't need to get out of their trucks.
