Rangi (Heaven) and Papa (Earth) had six sons. Because Rangi and Papa were always together, there was darkness all over the earth.
Day Four of Creation
The sons got together and decided they needed to separate their parents so there would be no more darkness. Although Tawhiri-ma-tea, the father of winds and storms, did not agree with this plan, the rest of the brothers went along with it anyways.
Day Five of Creation
Rongo-ma-tane, the father of cultivated food, tried to pull them apart but failed. Three of the other brothers also tried and failed. Finally, Tane-mahuta was able to separate his parents.
Day Six of Creation
Tawhiri-ma-tea, the father of winds and storms, was upset that his parents were pulled apart so he followed his father to the sky. To get back at his brothers, he sent down devastating storms to the earth. Tane-mahuta's trees were damaged and Tangaroa dove deep into the ocean to escape the storms.
Tangaroa left his grandchildren, the father of fish and the father of reptiles. The fish fled to the sea and the reptiles hid on land. Papa protected Haumia-tikitiki, the father of uncultivated food, and Rongo-ma-tane, the father of cultivated food, from the revenge of Tawhiri-ma-tea.
Tu-matauenga was the only brother to withstand the storms. He had been abandoned by his brothers when he wanted to kill his parents instead of seperating them. After the storms subsided, he planned his revenge on his brothers. He began to destroy all of his brothers one by one. Tawhiri-ma-tea was the only one not conquered and still brings storms to the earth today.
