The Project is a partnership between the Department of Conservation , Greater Wellington Regional Council, Ngāti Kahungunu ki Wairarapa, Rangitāne o Wairarapa, South Wairarapa District Council and Papawai and Kohunui marae.
The Wairarapa Moana area encompasses Lakes Wairarapa and Onoke, their surrounding wetlands, the Western Lake Scenic Reserve and Onoke Spit.
Lake Wairarapa is a shallow lake covering an area of 78 square kilometres. This makes it the third largest lake in the North Island of New Zealand. The area is situated in the southern catchment of the Ruamahanga River on the southern Wairarapa Plains.
