Which island is a protected reserve located on the west coast of New Zealand?

Kapiti Island is a protected reserve situated off the west coast of New Zealand, specifically in the Wellington Region. It was established as a wildlife sanctuary in 1897 and is renowned for its diverse birdlife, including species like the Kiwi and the Kākā, which are vital to New Zealand's natural heritage. The island's status as a protected area demonstrates a commitment to conservation, allowing for the restoration of native ecosystems that have faced threats from invasive species. Due to its conservation efforts, visitors to Kapiti Island can engage in eco-tourism activities while contributing to the preservation of New Zealand’s unique wildlife.

The other islands mentioned, such as Great Barrier Island, Stewart Island, and Chatham Island, have their own unique environmental and cultural attributes but do not share the same level of specific recognition as a protected wildlife reserve located on the west coast as Kapiti Island does.
