An asset or a pest? It all depends on how you look at drones. But for photographer Grant Sheehan, they've opened up all kinds of opportunities to photograph New Zealand from different aerial angles. Well, that was before new laws came in a couple of months ago restricting the way drones are used. Before then Grant was able to fly his drones over much of the country, over landscapes and scrap car yards, farms and city centres. He's brought together a collection of these photos in Eye in the Sky: A Drone Above New Zealand.
