The Historical Tarawhata Hot Mineral Baths were exploited following the search for oil in New Plymouth in. In 1909 the Bonithon Freehold Petroleum Company drilled a 3004ft (1 kilometre) well. They found no oil, but plenty of warm mineral water, which ran to waste until 1914. Then J Solomon, of New Plymouth built a 25 metre by 12 metre bath house which was used as a public swimming pool, as well as several private baths, all of which were enclosed in the same building.
In the mid 1960's the baths closed to the public. In 1999 the Bonithon Spa Health Co.Ltd re-established the Historical Bath House to a 5 star Mineral Health Spa.
