Emergency services are in attendance at an airfield in Manawatu.
A police spokeswoman said they were called just before 2.30 this afternoon to an incident at Feilding Aerodrome.
"A plane has gotten into some trouble and police, [ambulance] and fire [service] are on the scene."
She said it is understood there are no serious injuries.
"It is too early to say what happened - we haven't been on the scene long so not much more than that yet I'm afraid."
