 In Ngāti Porou and Ngāi Tahu's traditions, Uenuku would later shame Ruatapu, either for walking atop the roof of his house, or for using either his or Kahutia-te-rangi's sacred comb, or by being denied a tapu grooming of his hair before the family set out on a new canoe that Uenuku had built - regardless of the reason, he may not use the comb due to being the son of Uenuku's slave wife.Some tellings say Ruatapu is the firstborn child, but is still junior to his younger brother on account of the difference in their heritage.After this, Ruatapu lures the nobles of Hawaiki into a canoe, and then kills all of them, save for Kahutia-te-rangi who manages to escape and migrate to New Zealand with the help of the gods.
