Smythes Quarry is an extensive greywacke aggregate resource which is located on State Highway 2, 9 km’s east of Maramarua and has been in operation since 1960.

Initially supplying the rural market with farm grade materials, the quarry now produces a wide range of high quality products including basecourses, concrete aggregate and sealing chip as well as rural products to meet the growing demands of consumers in the Auckland and Waikato regions.

With sales around 1 million tonnes per annum, Smythes has been responsible for many infrastructure projects such as the Waterview Tunnel, Mangere Bridge Duplication and the Victoria Park Tunnel to name a few.

The total aggregate resource as determined by the International JORC code standards is in excess of 650 million tonnes (250 million tonnes of measured resource and 400 million tonnes of indicated resource). This will enable Smythes Quarry to meet the supply and demands for aggregate products in the Auckland and Waikato regions well into the future.
