Welcome to the official website of the Aggregate and Quarry Association of New Zealand. It is specifically for people who would like to find out more about quarrying and the role it has to play in our society. The quarrying industry provides essential materials to meet the demands of New Zealand’s growth and infrastructure.

A strong economy and excellent quality of life are literally built on a foundation of aggregates. Aggregates touch our lives everyday, from the driveway to the workplace. We drive, stand and walk on aggregates yet their importance to society is almost universally under estimated.

Without aggregates we would not have roads, railways, airports, schools, hospitals and other public buildings, clean water supplies, electrical power and a myriad of every day items such as glass and crockery.

Without aggregates we would neither be able to maintain our existing vital infrastructural facilities nor would the built environment be able to expand enabling economic growth both regionally and nationally.

We hope the information in this site outlines the importance of what we do, and in particular the high priority we place on environmental issues within the industry.


Quarries set environmental standards

- see full report here

The Aggregate and Quarry Association has recognised the following companies in its annual MIMICO Environmental Excellence Awards:

Gold       Holcim NZ Ltd, Tauranga Bay Quarry, Westport

Silver     Winstone Aggregates, Belmont Quarry, Lower Hutt

Bronze   Fulton Hogan, Gore Crushing, Gore 

Gold:  The Holcim NZ project is a major rehabilitation of the Tauranga Bay quarry and surrounding lands, following Holcim’s decision to close the quarrying and cement making facilities by mid 2016.  The aim is to rehabilitate the site into a recreation amenity for public use and restore surrounding lands to a maturing indigenous forest.  It is a major project drawing on Holcim’s global Quarry Rehabilitation Directive and involving working with a very extensive group of stakeholders.

The restoration, supported by a substantial budget, will create a mosaic of indigenous forest and wetland communities similar to what existed prior to European settlement.  

The enthusiasm for this restoration project, by both the entrants, was very evident despite the fact that they were going to work themselves out of a job over the next two to three years.

Most important they were very focused on ensuring what they finally create will be of real value to the local community, in amenity and economic terms: an addition to the tourist amenities of the area.

Silver: This innovative project uses environmental consent conditions at Winstone Aggregate’s Belmont Quarry to increase staff understanding of resource consents, and other regulatory regimes within which the quarry operates.  The quarry has 13 resource consents, 310 consent conditions, one wildlife permit, three certificates of compliance, seven management plans and must comply with the permitted activity rules for a Quarry Zone within the Hutt City Plan.

The magnitude of environmental regulation that must be complied with, particularly when extending a quarry, often turns environmental management into a ‘tick the box’ process.  This was thought to result in a lack of understanding of the wider purposes of environmental regulations.  This led to the decision to use compliance as an opportunity to increase staff understanding of its purpose and value to us all. 

Thus, the granting of the resource consents for the expansion provided the opportunity to increase site operator understanding of consents - and in the process make the conditions of consents more relevant to them.  This lead to the creation of Operation Gecko – born out of a requirement to translocate Ngahere Geckos, discovered on the proposed quarry site during pre consent surveys.  It is an initiative involving Winstone, Iwi (Tenths Trust locally and another Iwi on Mana Island) and DOC in the translocation of geckos to Mana Island.

The project illustrates the importance of quarries constantly engaging with their neighbouring communities and Iwi.  Wellington has only three major quarries to supply the region.  They are an essential regional asset and staff need to be seen to really care about the inevitable environmental impacts of quarrying to ensure continuity of business and community support.

Bronze: The focus is the long-term rehabilitation of Fulton Hogan’s Gore Crushing quarry area, known locally as Jacobs Springs, following aggregate extraction from former farmland.  Given this site adjoins the Mataura River, an internationally prized trout fishing river, it is essential the quarried areas are fully rehabilitated as extraction proceeds.  A two-year planting riparian programme is the heart of this winning project.

Gore Crushing is a small gravel extraction site based on a former livestock farm, and areas still to be used are leased for grazing.  Extraction of the gravel layers results in the formation of ponds that consent conditions require to be rehabilitated.  When the property was purchased, it was decided to create a quality wetland as extraction proceeded.  This has been done in close consultation with the local community through a community liaison group with members from local councils, DOC, Iwi and Fish and Game.

Riparian plantings have taken place over the last two winters following battering of pond margins and fencing.  Over 1000 trees, shrubs and flaxes have been planted per year sourced from a local nursery specialising in locally sources seed stock.  Three more areas are scheduled for planting over the next two years.  Good establishment of plantings has been achieved and ponds are now home to a large number of ducks and other water birds.  A large eel population is now established in the ponds and will, probably, increasingly attract water birds.

The long-term plan is to pass the whole Jacobs Springs site to the community when the quarry reached the end of its life.  Fulton Hogan plans to facilitate the formation of a Community Trust to take over ownership and management of the resulting amenity area.

 “These three winning entries are good examples of what can be achieved by enthusiastic, committed staff in companies that understand the value of being a good neighbour while operating their - at times challenging – businesses in an environmentally sustainable way,” said judge Dr Morgan Williams.

“I congratulate MIMICO for ongoing sponsorship of the award. It continues to provide an excellent incentive, as evidenced by the diversity of entries, for the industry to address, achieve and celebrate sustainable management of their part of the NZ environment.”

AQA hits back

The Aggregate and Quarry Association (AQA) has hit back at the bleak picture being painted of the quarry industry by unions.  Chief executive Roger Parton said the Council of Trade Unions (CTU) had painted a picture of an uncooperative industry that was actively avoiding being included in the Health and Safety Reform Bill.
These comments follow CTU general counsel Jeff Sissons saying the industry had campaigned not to be included in reforms made to the Health and Safety in Employment Act after the Pike River Mine disaster.

"That is not at all the case. We actually want to be in there," Parton said.

The AQA has been developing a code of compliance with Worksafe NZ and the association and industry as a whole is keen to get it into work practice, he said / read on
