A Department of Conservation worker lowered himself down a 3m mine shaft to rescue a kiwi after a member of the public heard its calls in a remote valley north of Greymouth.
Trevor Ellen was tramping in the headwaters of the Ten Mile Valley on Friday when he heard the bird's call, which he followed to find a great spotted kiwi down the hole. The area is full of abandoned coalmines and shafts, some almost a century old.
"He was down in an old sinkhole from the 1800s, like a mine shaft. I couldn't get him out on my own, so we went back the next day."
DOC biodiversity ranger Gavin Collis and Mr Ellen returned early on Saturday morning, on a three-hour rescue mission.
Mr Collis attached a rope to a punga tree, and lowered himself down. When he reached the bottom, the bird, probably a juvenile, did not run away, and let him pick it up.
