New Zealand is a country of stunning and diverse natural beauty: jagged mountains, rolling pastureland, 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.
