Aggregates are fundamental to the lives of everyday New Zealanders. Without an on-going supply of aggregates, the production of concrete and the development of buildings, roads and infrastructure would come to a standstill.
In 2017, New Zealand produced an estimated 45 million tonnes of aggregates including limestone and other products. That's around 9-10 tonnes per capita - or the equivalent of nearly a truck load for every New Zealander every year.
Over half of the aggregate produced in New Zealand is used on roads; a further fifth is used to construct commercial and residential building a half billion dollar industry – and more. The direct revenue earned from the 45 Mt of aggregates produced was $670M in 2017. The economic benefit of quarrying to our country (direct, indirect and induced) is $2.8 billion. Approximately 10,000 New Zealand jobs rely on aggregate.

For each tonne of aggregate produced, the first 30 kilometres it has to travel, doubles the overall cost. There are further costs for every extra kilometre – and these costs are passed on to consumers. That’s why it’s crucial that aggregates are sourced as close as possible to where they are needed.
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.
