Winstone Aggregates

Winstone Aggregates, leaders in the New Zealand quarrying industry, providing solutions that build the foundations of the communities we live in. Operating in the concrete, roading, rail, and wider infrastructure industries, we partner with our customers, communities, mana whenua and our teams to ensure sustainable outcomes. Our story is one of innovation, hard work, and enterprise. With 150 years of rich history in Aotearoa we have shaped the landscape and the skyline, building Auckland’s Harbour Bridge, the Sky Tower, and Wellington’s Sky Stadium, and after the tragedy of the Christchurch earthquake, supplying aggregate to rebuild the city.
