About quarrying in New Zealand

Using Aggregate

Aggregates are the most consumed bulk product in the world after water. New Zealand uses 9-10 tonnes of aggregate every year for each adult and child.

Building NZ

To build an average house, you need about 250 tonnes of aggregate - for use in concrete, asphalt, mortar and building products.
