Gannet Island (in the Māori Karewa language ) is a single small island in the Tasman Sea about 19 km from Kāwhia Harbor on the west coast of the North Island of New Zealand .
The island was designated as a nature reserve on May 1, 1980. According to a 1980 census, the second largest New Zealand breeding colony of the Australian gannet is on Gannet Island .
The island consists of the eroded remains of a tuff ring that was formed in eruptions of around 500,000 years ago . It is significantly younger and different in structure from the volcanic rocks of the nearby coast at Alexandra ( Mount Karioi and Mount Pirongia ) and Okete . The island is located on the eastern edge of the North Taranaki Trench. The island is 15 m high and extends about 65 m below sea level.
The island is also home to a significant colony of New Zealand fur seals . The Māori used the island as a burial place. Today the waters around the island are used for diving and fishing.
