In Hawaiian mythology, Hauwahine was a moûo and the guardian spirit of Kawainui Fishpond as well as PÃÂ'eo and Kaûelepulu fishponds.
In the Hawaiian language, the name Hauwahine literally means "female ruler".
It was believed that Hauwahine ensured there was enough food available for the people, but removed the fish from the pond if the people living in the area were oppressed by the aliûi. She was additionally believed to prevent sickness. Pollution and overgrowth were thought to be insults to Hauwahine, which was one motivation for the Hawaiians to keep the fishpond clean. The Hawaiian goddess Hiûiaka was believed to have fought all the moûo except for Hauwahine, for whom she chanted a mele.
NÃÂ PÃ Âhaku o Hauwahine, a basalt outcropping on the west side of Kawainui, was thought to be a favored location of Hauwahine. Yellow grass and rushes were believed to mark her location.
