A humpback whale had a lucky escape off the New Zealand coast, freeing itself from a crayfish pot line in a matter of minutes — and giving the Department of Conservation (DOC) a timely chance to remind fishers about keeping their gear whale-safe.
The entanglement happened at South Bay, Kaikoura, on Tuesday 19 May 2026 at about 11am. The whale became caught in a crayfish pot line but managed to shrug it off on its own after roughly ten minutes, before it could come to any serious harm.
DOC Marine Reserves Ranger Zac Penman was skippering a department boat in the area and watched the drama unfold. "We're really pleased this whale was able to get free on its own, but it could have been a much worse outcome," he said.
That margin between a good outcome and a grim one is the reason DOC is paying close attention. Humpback numbers have been climbing steadily as the population recovers, and the whales move along the New Zealand coast on their annual migration between May and August. More whales in the water, more often, means more chances for them to cross paths with fishing gear. Humpbacks are especially prone to entanglement thanks to their inquisitive nature, their habit of rolling, and their long fins and tail.
Penman's advice to fishers is about cutting the risk before it ever happens. He urged that pot lines be kept "only as long as they need to be, and that there's no loose rope floating on the surface." Tidy, taut gear with no slack rope drifting on top of the water is far less likely to snare a passing whale.
DOC also stresses that the public should not try to free an entangled whale themselves — it is dangerous for both the animal and the rescuer, and trained teams are equipped to do it safely. Anyone who spots a whale in trouble is asked to report it straight away. "Please report it immediately to our 24-hour hotline 0800 DOC HOT (0800 362 468)," Penman said.
For the crayfishers and recreational boaties working Kaikoura's productive waters, the episode is a reminder that a few minutes spent tidying lines can be the difference between an unremarkable day and a dead whale. This time, the humpback sorted itself out. The next one might not be so lucky.
