A plane has had to turn back to Christchurch Airport, after a smoke indicator warning light illuminated inside.

The aircraft - flight NZ5751 bound for Dunedin - landed safely. A Fire and Emergency New Zealand spokesman told Newshub passengers were unloaded before fire crews went on board to inspect.

The spokesman said firefighters from several stations across Christchurch were at the scene.

Passengers who spoke to Newshub say they could not see any smoke on the plane.

Checks are being made on the aircraft following the incident, an Air New Zealand spokeswoman said.
