The AQA is the national body representing companies producing most of New Zealand’s aggregate and limestone.AQA members produce somewhere in the vicinity of 40 million tonnes of aggregate, limestone and allied products a year. That’s about 10 tonnes – or a reasonable truckload for every New Zealander, young and old.
Our members produce the aggregates which form the foundation (and many walls) of almost every building across our nation as well most of our roads. Quarries also supply allied raw materials such as limestone, which help keep our farms productive.

The AQA represents aggregate suppliers on all manner of industry, government, health and safety, technical and other issues. We are a small organisation with an active board which meets monthly, supported by three part-time staff.

The AQA is an incorporated society, with board members elected from member companies around New Zealand. The AQA’s current chair is Brian Roche, who manages a limestone quarry at Te Kuiti. The AQA's Chief Executive, Roger Parton, is based in Wellington.
