Kamaiʻole is a chief mentioned in Hawaiian chants and legends. He was Aliʻi Aimoku (king) by usurpation and it is likely that he is just a mythical figure.
Myth of Kamaiʻole
David Malo mentions that Kamaiʻole seized the kingdom of Kanipahu of Hawaii, who fled to Molokai island.
Kamaiʻole took many wives and many of his subjects were very angry at him. They asked priest Paʻao how to kill the chief.
He was later killed by Kalapana of Hawaiʻi.
