Which two main islands make up New Zealand?

New Zealand is predominantly made up of two main landmasses known as the North Island and the South Island. The North Island is recognized for its vibrant cities, geothermal activity, and Maori culture, while the South Island is renowned for its stunning landscapes, including the Southern Alps and numerous national parks.

The North Island and South Island are distinct in their geography, culture, and climate, making them central to New Zealand's identity and tourism appeal. Given their prominence and the fact that they are the primary islands that compose the country, this choice accurately reflects the geographical structure of New Zealand, underscoring its significance in tourism and travel discussions.

The other options, such as East Island and West Island or combinations of other islands, do not exist as recognized major landmasses within New Zealand. Thus, they do not provide an accurate representation of the country's geographical layout.
