Garth Oakden and his wife Leigh are the founders of the Blue Duck Project. It was set up to bring whio back to their traditional habitat along the Tongariro River. Today, there are 800 traps set along 40 kilometres of the river, and it is common to see whio while rafting. I wonder what animals the traps are targeting.
