Dunedin airport had to be evacuated on Wednesday night after a threat to a plane from Wellington was reported.
An Air New Zealand plane had just departed when police in Wellington were alerted by a member of the public to a threat to the plane.
The aircraft landed without incident and was inspected. Other flights were delayed.
Dunedin Airport chief executive John McCall says the airport was evacuated for about two hours.
Police are investigating the incident and want to hear from anyone who saw any suspicious behaviour in the women's toilets at Wellington airport late on Wednesday afternoon or early evening.
