From one Pole to the other, Niwa scientists work in some of the world's most extraordinary landscapes. On any given day you might find a Niwa staff member under the ocean, on the ice, atop a mountain or deep in a lake or river.
These stunning environments are celebrated each year in an annual photography competition for staff.
The winner of this year's award was specialist diver Crispin Middleton, with his photo entitled Underwater Angel, taken near the Poor Knights Islands. Middleton has been trying to capture photos of flying fish for years, but every time he tried they would simply dart away. This year he managed to get his shot by hovering above the fish where they would linger for a few seconds before darting away.
The judges described the flying fish as like a piece of jewellery set against a black background.
"It has beautiful colour and is a very detailed image. An iridescent jewel against the dark of the ocean, beautifully captured and nicely lit to show all its subtle colour. This would have been a rare shot to capture."
