The Manukau Harbour (Auckland) is part of the rare Mauiâs dolphinâs natural habitat.
Set netting around the harbour mouth was banned since 2003 to protect the endangered species.
There has been controversy, particularly amongst fishermen, who say the dolphin does not venture
into the harbour but results of a new survey prove otherwise.Mauiâs dolphins have been detected at
three locations up harbour from the area closed to set netting. Detectors have picked up Mauiâs
dolphins 12 times says marine mammal researcher Michael Richlen.Mauiâs is New Zealandâs rarest dolphin,
only found on the west coast of the North Island. There are thought to be less than 150 living in the
wild.A three year study of the dolphins is being done by Otago Universityâs marine mammal research
group, with support from the Conservation Department.
