Entangled whales - Mike Morrissey

Every year thousands of whales have to be rescued after getting tangled in nets and ropes. Just last week a young humpback had to be cut free near Kaikoura by a specially trained team of volunteers. The Department of Conservation says members of the public often try to free entangled whales themselves. But a DoC ranger and a member of the International Whaling Commission advisory group on whale entanglements, Mike Morrissey, says they often do more harm than good.
