Hunua Quarry, at 489 Hunua Road in Hunua, Franklin, is a greywacke rock quarry run by Winstone Aggregates, an operating division of Fletcher Building. The quarry has been worked for more than 100 years, and the company says it is one of Auckland's largest. It supplies nearly 30% of the region's quality aggregate, mainly for roads and concrete. Its location beside the Southern Motorway is part of why the company calls it a key link in the region's infrastructure supply.
Recent news: Winstone wants to extend and deepen the Symonds Hill Pit on its freehold land, to keep the quarry running for another 80 years. The application will go through the Fast Track Approval Act, and environmental assessments are being carried out now. The company says the quarry is likely to reach the limits of its current consent within the next decade. Anyone with questions about the project can contact the team by email through the website.
Our pick in Hunua for anyone following Auckland's supply of roading and building materials.
