Simmonds Islands

The islands lie about 1 km north of Granville Point, at the southern end of Henderson Bay.

The islands are managed as a reserve by the Department of Conservation, and is a 'no landing zone'.

The islands are home to a variety of sea and shore birds, including the Buller's shearwater which, until discovered breeding here in 1990, was thought to breed only on the Poor Knights Islands.

[1] A 1966 research paper described the islands (and their flora and fauna) in detail.

The paper noted that they are separated only by a "boulder beach", and described the "Anapuhipuhi Blowhole" - to the south-east of the easternmost main islet (now named "Terakautuhaka Island") as "produc(ing) a spray rising 40 to 45 feet" (12 to 14m).
