What it is
Aitu is a word found throughout Polynesia that names spirits, ghosts, or disasters. In Tonga, the variant ʻaitu refers to minor gods who watch over families and villages. These figures often appear as plants or animals and act with cruelty. In Tahitian, the word can mean god or spirit. For Māori people, it stands for sickness or demons. The related form aituā describes misfortune or accident. Across many islands, the term marks something beyond human control.
Where it comes from
Tongan stories say these trouble-making gods came from Samoa. In the Cook Islands, ancient tribes named Aitu arrived from the east. Tradition holds that some settled on Aitutaki, Atiu, and Mangaia. On Aitutaki, they were driven away or destroyed. On Mangaia, they were killed to feed the gods. A large oven called te umu Aitu remains there as proof of those sacrifices.
