Blackhead Quarries is a rock quarry at Blackhead, on the seaward side of Green Island in Dunedin, reached from Blackhead Road. It was set up in 1986 as a joint venture between Palmer & Son and Fulton Hogan, and its main purpose is quarrying rock at the site.
The quarry supplies aggregate, sand and crushed rock, and it offers drilling and crushing services. The business says these materials and services go to construction projects across New Zealand. For a builder or contractor in Dunedin who needs aggregate or sand, the quarry's own rock supply is the practical reason to contact it.
