    New Zealand will create one of the largest marine protected areas in the world, spanning an area of 620,000 sq km.

    The Kermadec Ocean Sanctuary (保护区) will be one of the world's most significant fully protected ecosystems, the prime minister of New Zealand, John Key, told the UN General Assembly in New York.

    The sanctuary is in the South Pacific Ocean, about 1,000 km north-east of New Zealand, and expands a marine reserve that surrounds some small islands. The area is considered important in terms of biodiversity, featuring nearly 35 species of whales and dolphins, 150 types of fish and three of the world's seven sea turtle species. It is also geologically significant, including the world's longest chain of underwater volcanoes and the second deepest ocean trench, into 10 km underwater — deeper than Mount Everest's height. The scale of the sanctuary will dwarf (矮化) any previous New Zealand's protected area, spanning twice the size of the country's mainland. It will cover 15% of New Zealand's economic zone.

    Commercial and recreational fishing will be completely banned, as will oil, gas and mineral prospecting (勘探), exploration and mining. Key's government aims to pass legislation establishing the sanctuary next year.

    "The sanctuary is a world-class, unspoiled marine environment and New Zealand is proud to protect it for future generations,"Key said."New Zealanders value our coasts and oceans, which are an important part of our culture, economy and environment and we are committed to managing them sustainably. Creating protected areas will support not only our own fisheries, but those of our Pacific neighbors, adding to New Zealand's efforts to help grow Pacific economies through the responsible management of their ocean resources."

    Nick Smith, New Zealand's environment minister, said the sanctuary might impose a cost upon the mining industry but that it is important to protect the ocean before exploration takes place."New Zealand needs to use its vast ocean resources for jobs and exports in industries like fishing, aquaculture, minerals and energy, but we also need to set aside special areas where nature comes first and marine life is fully protected,"Smith said.

    New Zealand will monitor the area via its navy and satellite technology. The Kermadec region will join three other key areas in the Pacific protected by the US, the UK and Australia.

    Matt Rand, director of the Pew Charitable Trusts' Global Ocean Legacy (遗产) campaign, welcomed Key's announcement."New Zealand will create the gold standard of conservation areas in the sanctuary, preserving one of the few ly unspoiled areas of ocean on Earth,"he said."This commitment is an exciting step toward meeting global goals to safeguard at least 30% of the ocean through fully protected marine reserves."
