Aerowork says it is in shock after one if its pilots was killed in a light aircraft crash this morning.
Police said emergency services were responding to the crash near Ruakiwi Road after being alerted about 7.30am.

Aerowork said it was a very sad and traumatic day for their tight-knit team.
The man was a very experienced and dedicated pilot, the company said.
A spokesperson said it was hard to say what had happened at this time, and they would be waiting for a full investigation to take place.
Carterton mayor Greg Lang said the incident was devastating, "especially in a close-knit, rural community."
