With a surface area of 616 square kilometres (238 sq mi), it is the largest lake by surface area in New Zealand, and the largest freshwater lake by surface area in Oceania. Lake Taupo has a perimeter of approximately 193 kilometres, a deepest point of 186 metres. It is drained by the Waikato River (New Zealand's longest river), while its main tributaries are the Waitahanui River, the Tongariro River, and the Tauranga-Taupo River.

According to geological records, the volcano has erupted 28 times in the last 27000 years. It has predominantly erupted rhyolitic lava although Mount Tauhara formed from dacitic lava. The largest eruption, known as the Oruanui eruption, ejected an estimated 1170 cubic kilometres of material and caused several hundred square kilometres of surrounding land to collapse and form the caldera. The caldera later filled with water, eventually overflowing to cause a huge outwash flood.[3] Several later eruptions occurred over the millennia before the most recent major eruption, which occurred in 180 CE.
