Membership of the Institute is open to everyone in a position of responsibility with appropriate qualifications and/or experience employed in, or supplying to, the surface mineral extractive and processing industries in any country of the world.
This includes hard-rock quarrying, sand and gravel (both land-based and marine-dredged), recycling, special sands, cement, lime, gypsum, clays, coal, slate, asphalt, ready-mixed concrete and concrete products.
The Institute also embraces all the professional and consultancy services which support the industry. There is a dedicated Supply Industry Committee representing those engaged in the supply of plant, equipment, material and services which advises Council.
As well as having a broad industry base, Institute membership reflects the multi-disciplinary nature of the business it serves and keeps an open door to everyone from a chief executive to a trainee manager.
Accordingly it draws its support from all those who contribute to the successful operation of the minerals industry today – geologists, surveyors, engineers, production managers, quarry and site managers, commercial and financial managers, technical and laboratory staff, landscape architects and environmental specialists, sales and service engineers, health and safety officers/inspectors, planning officers and a host of others in positions of responsibility.
Members are kept up to date on topical events – IOQNZ has seats on the Minex and MITO boards, as well as representatives on the (WorkSafe NZ) Board of Examiners.
