Almost 300 aircraft were reported as being in the wrong place in New Zealand skies last year, the Civil Aviation Authority says.
Poor radio communication was often the cause of these planes being in the wrong spot.
The comment comes as the Civil Aviation Authority (CAA) launches its annual AvKiwi Plane Talking roadshow which travels the country with safety messages for all pilots.
This year the focus is on what happened when radio communications went wrong, and what can be done about it.
"Poor radio calls can lead to airspace busts, blocked runways, near misses and even collisions.''
