A humpback whale missing most of its tail has been spotted off Kaikoura.
It appeared the whale's tail flukes were missing but it was relaxed and moving well, Department of Conservation Kaikoura ranger Mike Morrissey said.
Mr Morrissey speculated the humpback's tail was torn off as a result of the whale getting badly entangled in rope.
He went out by boat to check on the whale on Monday and estimated the whale to be two to three years old.
He noticed the wounds had healed which indicated it had lost the flukes some time ago.
