Granite in New Zealand is confined to the South Island and Stewart Island. There are three major meridionally trending belts in north-west Nelson-Separation Point to Mt Murchison, Kahurangi Point to Ahaura River, and Paparoa Range to Kongahu Point. Isolated granite masses are known in West-land and extensive areas in: Fiordland and Stewart Island.
