Aggregate & Quarry Association


The AQA represents members on all manner of industry, government, health & safety, technical and other issues.

About Us

AQA members produce in excess of an estimated 45 million tonnes of aggregate, limestone and allied products each year. That’s about 9-10 tonnes – or a truckload, for every New Zealander, young and old. Our members produce the aggregates which form the foundation and 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, 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 chair is Peter Walsh, who is Fulton Hogan’s North Island Resources Manager. The AQA's Chief Executive is Wayne Scott, who is based in Wellington.
