It has an explosion crater around 700 m (2,300 ft) wide, with a surrounding tuff ring. The present basin is slightly larger than the original maar crater. Sediments in the basin provided the first high-resolution palaeo-environmental reconstruction for northern New Zealand of the last 130,000 years.:367 The basin supports recreational water sports activities for the local population.
