Minerals were extracted by Maori at quarries, eg obsidian and argillite. The first significant extractive industry in New Zealand was the 1859 copper mine on Kawau Island. However, relative to gold and coal mining, New Zealand has not had an abundance of other precious mineral mining. Quarrying has been an important but unsung activity

Coal. New Zealand’s first coal was dug from a small seam at Whanganui Inlet and shipped to Wellington in the Jewess in 1840. Mines at Pākawau and Pūponga were developed in the late 1890s, with Pūponga coal shipped to Nelson, Taranaki and Wellington. In 1911, at its peak, Pūponga employed 70 men and yielded 30,000 tonnes of coal.
