Aptly described as ‘gifts from the earth’, thermal springs occur in many parts of New Zealand. Most are scattered throughout the Taupo Volcanic Zone in the central North Island, but some are in areas of extinct volcanic activity such as Northland, the Coromandel Peninsula and the Bay of Plenty. Others lie in non-volcanic areas, along faultlines, particularly in Westland and North Canterbury. They are formed when rainwater seeps down through rock towards the heat source deep beneath the surface and then rises again. The hot water dissolves minerals in the rock, and the mineral content as well as the temperature of hot springs varies according to locality.
