It's been revealed a third Sea Lion killed in the Catlins was likely stabbed by a human. Now a reward for information leading to the killers convictions has been more than doubled to twelve thousand dollars thanks to donations. A baby female Sea Lion was shot and left to die in the Catlins Estuary in the lower South Island in September last year. The following month the pup's mum was found shot dead. A third sealion had to be euthanised in November after she was found badly injured at Waipati Beach. The NZ Sea Lion Trust's Jordana Whyte spoke to Lisa Owen.
