In
Polynesian mythology (specifically:
Kiribati),
Kai-n-Tiku-Aba ("tree of many branches") is a sacred tree located in
Samoa, which grew on the back of a man named
Na Abitu[?].
Koura-Abi[?], a destructive man, broke it. Sorrowful, the people of Samoa scattered across the world.
This myth is known from Kiribati, and explains why they migrated there from Samoa.
