The potential beginning of a postwhaling recovery in New Zealand humpback whales (Megaptera novaeangliae)
Between the 1940s and 1970s Southern Hemisphere populations of humpback whales (including eastern Australia and Oceania populations) were hunted to near extinction by extensive commercial whaling activities in Antarctica, with fewer whales taken in shore whaling operations in New Zealand, Australia...
