Legend has it that beautiful twin sisters, Retutai and Tangimoana lived on the stony banks of the Ruamahnga River. A handsome local warrior named Rautoroa heard of their beauty and came bearing gifts. Their hearts went out to him and soon the sisters became jealous of each other. Tangimoana cruelly tricked her sister and married Rautoroa. Heartbroken Retutai climbed up into the mountain mists and was never seen again.
