In Māori mythology, Hema is a son of Whaitiri and Kaitangata and the father of Tāwhaki and Karihi.
[1] In North Island stories, he was killed by the Ponaturi, evil creatures who live by day in the water.
[2] Tāwhaki, Karihi and their mother trick the Ponaturi into entering a house, and then locked them in, claiming there was still time before the dawn.
They then opened the door after sunrise, and the Ponaturi were killed by the exposure to sunlight (Tregear 1891:61, 496).
In Hawaiian mythology, Hemā and his brother Puna are sons of the man named Aikanaka by his consort, Hinahanaiakamalama — often simply called Hina.
