The name Rotorua comes from Māori, the full name for the city and lake is Te Rotorua-nui-a-Kahumatamomoe. Roto means 'lake' and rua means 'two' or in this case 'second' - Rotorua thus meaning 'Second lake'. Kahumatamomoe was the uncle of the Māori chief Ihenga, the ancestral explorer of the Te Arawa. It was the second major lake the chief discovered, and he dedicated it to his uncle. It is the largest of a multitude of lakes found to the northeast, all connected with the Rotorua Caldera and nearby Mount Tarawera. The name can also mean the equally appropriate 'Crater lake'.
