Lake Rotorua

Lake Rotorua fills the Rotorua Caldera, a volcanic crater that collapsed after an eruption about 240,000 years ago, and covers almost 80 km², with a mean depth of only 10 m. The city spreads along its southern shore, and Mokoia Island, a later volcanic dome near the centre, is the setting of the Māori story of Hinemoa and Tūtānekai.
