In Polynesian mythology, Rehua is a star god, who lives in Te-Putahu-Nui-o-Rehua in Rangi Tuarea, the tenth of twelve heavens in Polynesian lore. He is a son of Rangi and Papa, and the father of Kaitangata, as well as the ancestor of Maui.

Rehua invented the Tui (a staple food of the Polynesians) by shaking it out of his hair.
