Eastern Australia (E1 breeding grounds) may be a wintering destination for Area V humpback whales (Megaptera novaeangliae) migrating through New Zealand waters
Investigation of the migratory movement of humpback whales past New Zealand in the 1950s and early 1960ssuggested that the primary factor influencing the migratory flow past New Zealand was behaviour associatedwith breeding and feeding.
