A Nelson forest company halted operations when they came across a kea nest with two chicks inside.
The nest was found in a disused culvert at a Tasman Pine Forests skid-site in the Motueka Valley, in late-November.
The forest company has been thanked by the Department of Conservation (DOC) for suspending operations near the nest until the chicks start to fly and leave in about a month.
"Work with vehicles and machinery around the nest might've damaged the nest or caused disturbance to the kea family that could be detrimental to their welfare," says DOC operations manager Chris Golding.
"Kea is an endangered species and being able to safely raise chicks in their nests is important to increasing kea numbers."
The kea, which was crowned New Zealand's Bird of the Year in 2017, is the world's only alpine parrot with between 3000-7000 of them left.
The Kea Guidelines for Plantation Forestry was developed to provide advice for preventing kea damage to forestry equipment and for protecting kea.
"Kea are inquisitive and social birds and, because of this, they interact with people and property," says Kea Conservation Trust conflict co-ordinator Andrea Goodman.
"The guidelines include ways for forestry companies to discourage kea from hanging around harvest sites and for protecting equipment if they are around.
"I think it's awesome that the guidelines we've spent two years developing actually work," she said.
