From being reluctant to dip their toes in the water to frolicking in the Tongariro River, three whio (blue ducks) have found new homes in the wild near Poutu Intake.
Before their release, the juvenile whio had been busy building confidence at the hardening facility at Tongariro National Trout Centre.
Whio are river specialists, living on fast-flowing rivers.
Hardening facility coordinator Karen Ardin says staff and volunteers noticed the birds acting differently on arrival.
"Two were standouts when they arrived as they just didn't want to get in the water. Not wanting to swim is like not knowing how to be a duck."
