The details which reveal courage as a Māori value are:

“In subduing Tawhiri, Tū created peace in the heavens and the earth.”

“Tū opened his mouth and ate his brothers to punish them for their cowardice.”

“The Māori, the humans who are able to master anything that they decide to conquer”

The Maori creation myth tells the story how humans were born and how nature helped in their birth by sacrificing themselves. According to this creation myth, the earth and heaven were once joined as Ranhinui.   Papatuanuku was the sky father and the mother Ranhinui was the Earth and they had many children. The children lived in the darkness and wanted to live in the light. The children separated the parents in order to live in the light. The parents continue to grieve for each other until the present day. The Maori myth features courage over anything. They valued family, nature and courage.
