Technical & Planning


The AQA engages with local and central government on planning issues, specifications and sustainability issues; and it works and cooperates with other industry organisations on behalf of the quarrying and aggregate sector. The Technical Committee includes members from the wider industry and is also represented on several external committees in the roading, asphalt and concrete sectors.

The Technical Committee’s role is to improve the technical knowledge of New Zealand aggregates for our members and users of our products and assist members to attain best practice in complying with operational, environmental and regulatory requirements. Some content which you can find in the members only section, is listed below.

For all technical queries, please contact our Technical Adviser, Mike Chilton:

Manufactured Sand

Aggregate (crushed rock, gravel, and sand) is an essential resource for the construction sector, housing, transport infrastructure and climate change adaption. Due to unprecedented levels of construction and infrastructure development activity, there is growing demand for aggregate which is in short supply in many parts of New Zealand. Where resources are scarce or consenting time frames impact supply, it is important to utilise quarry products effectively.

Sand is currently the second most used raw material on the planet, it is used across several sectors, is easy to obtain and suitable for many purposes. The demand for its use in construction, microchips, glass and in cosmetics has been rapidly increasing with the increase of urbanisation and it is becoming less readily available because of this growth, and the closure of unsustainable sand extraction operations in many parts of the world.

The purpose of the Planning Committee is to provide advice to members and the AQA Board on policy and planning issues relating to the establishment, consenting and operation of quarries and the production of aggregates, lime and other materials.

AQA currently submit on all regional and district plans and encourage all of our members to submit on those plans that affect them. To assist you we have made a document – Key points relating to quarries for use in submissions on resource management policy and district plans, find it in the members only section. 

The Guideline document is designed to assist members in preparing submissions on regional or district plans, and preparing development applications or similar Resource Management applications. It contains key points designed for members to be able to cut and paste into submissions on resource management policy, district plans etc. Please use these key points, as relevant, in your submissions.



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.


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


The quarry industry is committed to working alongside local communities and follows stringent planning, environmental and operating conditions.
