In one story, Uenuku visits a woman named Iwipupu over the course of many nights, while her husband Chief Tamatea-ariki-nui of Hawaiki is away from home. Iwipupu falls pregnant to the supernatural entity, with his instructions being to name the child "Uenuku-titi" if it was a girl, and "Uenuku-rangi" if it is a boy. As soon as Tamatea returned, Iwipupu told him she had been visited by somebody of his likeness, and then he figured that it was the spirit of Uenuku who made her pregnant.
