Which island nation is a major producer of kiwifruit and is home to the flightless bird known as the kiwi?

New Zealand

New Zealand is the primary home of the kiwi bird, which is so unique that it lays one of the largest eggs in proportion to its body size of any bird species. While the kiwifruit is synonymous with the country today, it was actually originally known as the 'Chinese gooseberry' before being rebranded for international export in the 1950s.
