Which country is known for being the origin of kiwis?

New Zealand is renowned as the origin of kiwis, both the fruit and the bird that symbolizes the country. The kiwi fruit, originally called the Chinese gooseberry, was cultivated in New Zealand in the early 20th century and became popular worldwide under its current name, reflecting New Zealand's national identity. While other countries such as Australia and Chile also grow kiwis, New Zealand is credited with developing the commercial production and global distribution of the fruit, making it synonymous with the country itself. Therefore, New Zealand is the correct choice because it is where the kiwi became a significant agricultural product, representing the nation on the world stage.
