The New Zealand continent

New Zealand’s islands are the higher ground of a mostly submerged continent called Zealandia, which is about two-thirds the size of Australia. Under water, the continent supports inshore fisheries, and parts of it may be mined for minerals in the future. Off the Taranaki coast it has been mined for oil and gas since the 1970s.
