Winstone Aggregates

Pioneers in the New Zealand quarrying industry, Winstone Aggregates moves the earth to bring Aotearoa into the future. Operating in the concrete, roading, rail, and wider infrastructure industries, we interact with various stakeholders including staff, business partners, customers, and commercial associates. On top of this, we also have the responsibility to be respected employers and good corporate citizens. 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, supplied aggregate from our Yaldhurst quarry to rebuild the city.
