Māmari
In Māori tradition, Māmari was one of the great ocean-going, voyaging canoes that was used in the migrations that settled New Zealand.
Mamari was the third waka to arrive with the tangata Ruanui. The traditions of the Aotea, Horotua and Mamari waka mention that kiore (rats) were passengers on their voyages to New Zealand. Carvings on a window frame of Te Ohaki Marae in Ahipara depict the story of Ruanui's kiore. When he arrived into the Hokianga Harbour, he released them onto an island called Motukiore (rat island).
