Hunua Quarry Expansion Approved to Boost Auckland’s Aggregate Supply
Auckland’s Hunua Quarry expansion has received Fast-track approval, allowing Winstone Aggregates to increase production capacity to 5.4 million tonnes annually by deepening the Symonds Hill Pit and addressing regional aggregate shortages. This approval, the 37th through the Fast-track process, aims to reduce reliance on imported aggregate, lower construction costs, and mitigate environmental and traffic impacts through specific conditions. The expansion, alongside similar projects at Drury and Kings quarries, supports Auckland’s housing and infrastructure needs while promoting economic and environmental benefits.
