All of NZ is in the “Ring of Fire” area for old volcanoes...
Yes,I know that NZ is an earthquake/volcano zone.In fact,I once went to a town on the North Island called Rotorua which is a big geothermal energy area.I guess they pipe this energy into homes and businesses for free heat and things like that.The town *did* have a pretty strong sulfur smell to it...at least parts of the town did.
