Winstone Aggregates' Hunua Quarry has the green light to help keep Auckland building for decades to come.
The quarry expansion has been approved under the Fast-track Approvals Act, unlocking access to around 225 million tonnes of high-quality rock and an estimated 50 to 80 years of supply.
Already supplying almost 30% of Auckland’s aggregate, Hunua has helped shape the region’s roads, bridges and building foundations for around a century. This next chapter will keep essential construction materials close to the projects that need them.
It’s a significant milestone for Winstone Aggregates, our Heavy Building Materials Division, and Fletcher Building that will strengthen the long-term supply of locally sourced materials to support housing, infrastructure and the region’s growth.
