Which island of New Zealand is known for its geothermal activity?

The North Island of New Zealand is renowned for its significant geothermal activity, particularly in areas such as Rotorua and Taupō. This region is characterized by natural phenomena like geysers, hot springs, and mud pools, which are a result of the tectonic activity associated with the Pacific and Indo-Australian tectonic plates. Rotorua, in particular, is a major tourist destination due to its geothermal features and cultural significance to the Māori people.

This geothermal activity not only plays a crucial role in shaping the landscape but also offers various recreational and therapeutic experiences for visitors, drawing thousands of tourists each year. In contrast, while the South Island has its own unique attractions and natural beauty, including the Southern Alps and beautiful fjords, it does not share the same level of geothermal activity as the North Island. Stewart Island and Chatham Island, while fascinating in their own rights, are also not associated with significant geothermal phenomena.
