Disagreements between brothers

When Tāwhirimātea (god of storms) made war against his brothers for the separation of Rangi and Papa (sky and earth), Ikatere and Tū-te-wehiwehi were among those who had to flee from his wrath for their survival.^[1][2] The two argued over whether they should stay in the sea or go to the land.^[2] Ikatere chose to keep his children, the fish, to the sea,^[1] while Tū-te-wehiwehi chose to take his children, reptiles, to the land.^[2] A saying that refers to the choices they made for their descendants goes as such:
