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.

A tramper's headlamp arcs a trail through the subterranean recesses of New Zealand's southern‑most mine. The 85-metre tunnel, driven into solid granite, survives as one of a handful of relics from New Zealand's only tin rush—a stampede of ill-prepared men into the miserable weather and impenetrable scrub of southern Stewart Island ...

Some of New Zealand's biggest coal mines are in these Cretaceous rocks, particularly near Greymouth, but also at Kaitangata, Ohai, and Collingwood. Igneous activity was widespread in the Cretaceous. Large areas of granite at Separation Point, the west of the South Island, Fiordland, and Stewart Island were intruded during the Cretaceous.

The West coast of the South Island of New Zealand has some of the oldest structural units in New Zealand, with strong similarities to terranes in eastern Australia. This area contains highly prospective geology with granites of a similar age and type to the Timbarra gold deposit in northern New South Wales (Mustard, 2004) or the Kidston gold ...

Lignite is New Zealand's largest fossil fuel energy resource. The main deposits are well known, with technically and economically recoverable quantities in the 10 largest deposits established at over six billion tonnes. There are 22 active coal mines in New Zealand, 17 of which are producing.
