A male orca, known as Koru, breaches off the coast of Kaikoura. Koru was among a pod of at least 15 orca spotted off the coast by Blackcat Cruises last week. Dolphin Encounter owner and operator Dennis Buurman said another well-known orca, Ben, was also among the group. Ben found fame in June 1997 after being stranded on Northland’s Mangawhai Beach, before being refloated. He is identified by his deformed dorsal fin after having been run over by a boat some years ago.
