Great Barrier Island, the largest island off the coast of New Zealand's North Island and the outer-most island of the Hauraki Gulf, is comparatively undeveloped and free from many of the animal pests that have taken their toll elsewhere in New Zealand. As a result there is a superb natural landscape and a high number of rare native plants and animals as well as numerous well-preserved historic sites. This guidebook describes Great Barrier Island - its history and natural features, including flora, fauna, habitats and endangered species, terrestrial, freshwater and marine. Profusely illustrated in colour, and with maps and sketches, this is an essential resource for all visitors. First published in 2001, revised in 2004 and updated 2011.
