https://www.stuff.co.nz/busine...In the clear winter sky above Central Otago, a drone follows a fenceline up a hill.
It darts and slows making small detours to the left and right, and now and again hovers in one spot. Some of the fenceline sags under drifts of snow, and here the drone pauses.
Two years ago Kawarau Station owner Jon Anderson invested in the drone, with an eye on using it to check fences during heavy snowfalls. Doing this on foot was time-consuming and heavy on manpower, and the drone could do it in a matter of minutes, he says.
