Abstract: A week-long visit to Te Niho a Kewa (Solander Islands) was undertaken by a joint Macquarie University - GNS Science geological expedition in February 2010. During this time, most of the shoreline of the main Solander Island (Hautere) was traversed from a camp in Eastern Bay. Comprehensive geological observations, photographic coverage, and rock samples were obtained, and will allow a revised geological map of the main island to be compiled. Little Solander Island was only over-flown, and one grab sample obtained. The lower parts of both of the Solander Islands are composed of plagioclase hornblende andesites. Altered joints, veins and cataclastic (faulted) zones cut lavas in several places. Bedded block and ash flows and volcaniclastic breccia form the upper parts of both islands. Peaty scree and landslide deposits mantle many lower slopes. Dikes and faults are less common than shown on previous geological maps. Wildlife sightings and archaeological sites were also recorded.
