Tongariro whio death prompts a reminder to take fishing line home

DOC has reported the death of an endangered whio after it became entangled in fly-fishing line on the Tongariro River. It’s a practical reminder that a small amount of lost tackle can cause serious harm.

What is known

An angler found the bird on 10 September. DOC’s 17 September account says line was wrapped around its wings and a hook was caught in a foot. The wing damage could not be repaired, and the bird was euthanised following specialist veterinary assessment.

The report does not establish exactly how the entanglement happened. It would be wrong to assign blame to a particular person or turn an unknown detail into fact.

The actions DOC is asking for

DOC asks anglers to avoid casting near whio and to remove discarded line and flies. Injured or distressed native wildlife can be reported to DOC on 0800 362 468.

Our practical suggestion is to make line collection part of the pack-up routine: keep a small, secure container with your tackle for loose line and hooks, then dispose of them properly at home. Don’t leave sharp tackle loose in a bag.

Make the last check count

Look over the place where you changed flies or sorted gear before leaving. Small offcuts are easy to overlook. If you find an injured bird, seek DOC’s advice rather than attempting an improvised rescue that could make the injury worse.
