James' first foray into film came when he took a camera along when he was working as a possum trapper so he could show his friends and family what he got up to all day.
He demonstrated how to trap the pests before giving them "a little pat on the head with my Whispering Stick" a hammer.
He went on to make dozens of videos of his missions in the bush. Alone, or with his mates, he demonstrates everything from tracking, hunting and fishing to identifying edible native plants.
Born in Napier, he settled in Ross on the West Coast and runs Eco Rafting Adventures.
Co-star Tebbutt guest-presented Saturday Kitchen on BBC One, and co-hosted Market Kitchen: Big Adventure. He has also been a contributor to Saturday Kitchen and appeared on the Great British Menu.
James could not be reached for comment, but announced on his Facebook page yesterday it would soon air.
