On the banks of the Waikato River, Winstone Aggregates has taken quarrying to the next level in a partnership with local iwi, and nature conservation work. At Pukekawa quarry, the wetlands and other waterways are on the rebound.
Pukekawa quarry has been operating on the banks of the Waikato River since the 1920s, a hard rock basalt quarry, and for the past 10 years, a sand extraction operation from the Waikato River. As part of the ongoing development and future of this North Waikato / South Auckland site, Winstone Aggregates prioritises the managing of environmental impacts, and engagement with iwi and local community
Twelve people are employed on site, each multiskilled to cover a full range of materials extraction, processing and sales loadout. River dredging bringssand ashore for processing through a series of screens and gravity spirals, while basalt is blasted from the rockface and fed through a four-stage crushing and screening process, to produce a broad range of sand, roading and building products.
