North Island , New Zealand

According to Maori, the North and South Islands of New Zealand arose through the actions of the demigod Maui. Māui and his brothers were fishing from their canoe when he caught a great fish and pulled it from the sea. While he was not looking his brothers fought over the fish and chopped it up. This great fish became the North Island hence a Māori name for the North Island is  Te Ika-a-maui (The Fish of Māui). The mountains and valleys are believed to have been formed as a result of Māui's brothers' hacking at the fish.
