Southern Right Whale with calf in Wellington Harbour

Wellington's whale watching season isn't over yet with a Southern Right Whale and its calf spotted in the harbour. Last month another Southern Right Whale, affectionately named Matariki, spent several days in the harbour. The Department of Conservation says people should stay at least 200 metres away from the new whales, further than the usual 50 metres stand-off distance for marine mammals. Nadine Bott is a whale expert. She talks to Susie Ferguson.
