Aviation regulators say there are safety risks as an increasing number of unmanned aerial vehicles known as drones take to New Zealand skies.
Drones were developed principally for military use, but now civilians are using the same technology for mapping, surveying and filming.
But its not as easy as it looks, as flight paths and buildings often intersect, with potentially disastrous consequences.
“There’s a lot to know about wind and there’s a lot to know about the technology,” says Sycamore UAV director Ben Forman.
“You can’t just pick one of these things up and expect to be a pro.”
