Hydraulic fluid caused smoke in the cockpit of a plane which made an emergency landing in Nelson last night, the Fire Service says.
An Air New Zealand plane carrying 50 passengers made an emergency landing at Nelson Airport, after reports of smoke in the cockpit.
The Fire Service received a call just before 8pm and sent six fire engines to assist.
Spokesperson Jaron Phillips said the plane landed safely.
A St John ambulance spokesperson said two ambulances were sent to the airport.
One person was assessed but did not require further treatment.
A witness said most of those on board a plane appeared calm when they got off the plane.
Nelson resident Angela Bezett said passengers were talking about a lot of smoke in the cabin. "Some of the ones that were up close were a bit worried about fumes," she said.
