Mount Hikurangi is of great spiritual, cultural, and physical significance to Ngāti Porou. It is the iwi's most important icon, and in Māori mythology, was the first part of the North Island to emerge when Māui, an ancestor of Ngāti Porou, pulled it as a giant fish from the ocean. According to these beliefs, his waka, Nukutaimemeha, became stranded on the mountain, and lies petrified near the mountain's summit. Another of Ngāti Porou's mythological ancestors, Paikea, is also associated with the mountain. According to myth, Paikea's younger half-brother, Ruatapu, attempted to kill about 70 of his older kin (brothers) at sea in Hawaiki to exact revenge on his father for belittling him as a low-born son of a slave. The massacre, called Te Huripūreiata, was survived only by Paikea, who called on the sea gods and ancestors to save him. Paikea travelled to New Zealand on the back of a whale, but Ruatapu sent a great flood to kill the survivors in New Zealand, called Te Tai a Ruatapu. Mt. Hikurangi became a refuge for the people from this deluge.
