Ohakune-based Couch told the Herald Whaia joined him on the slopes most days and while he had not yet had to do a real-life rescue, he was trained and ready.
"[His job is to] detect people under the snow. He does a sniff over search and then he starts digging [when he locates a trapped person].
"He's quite hyperactive, so he's had to have a crash course in chilling out."

Whaia, who spent almost six weeks in vet care, was walking again but ongoing treatment, including at least one more operation, had costs Couch thousands.
Pet insurance had covered just under half of the $10,000 bill, but Couch, whose dog rescue work is voluntary, must pay the remainder and any future costs.
