New Zealand is a country of stunning and diverse natural beauty: jagged mountains, rolling pasture land, steep fiords, pristine trout-filled lakes, raging rivers, scenic beaches, and active volcanic zones. These islands are one of Earth's most peculiar bioregions, inhabited by flightless birds seen nowhere else such as a nocturnal, burrowing parrot called the kakapo and kiwi. Kiwi are not only one of the national symbols – the others being the silver fern leaf and koru – but also the name New Zealanders usually call themselves. These islands are sparsely populated, particularly away from the North Island, but easily accessible. There are sparklingly modern visitor facilities, and transport networks are well developed with Airports throughout the country and well maintained highways. New Zealand often adds an adventure twist to nature: it's the original home of jet-boating through shallow gorges, and bungy jumping off anything high enough to give a thrill.
