Our Promise to our People

Working to create positive, sustainable environmental impact and safe work sites


Winstone Aggregates makes a commitment to take care of the wellbeing of the environment and our people. We invest in the health and safety of our people, the communities in which we operate and the environment, because we care. 

Our larger quarries have Site Liaison Groups to ensure environmental management and operational capability can be discussed with stakeholders. We have environmental programmes that plant native trees and save at-risk native fauna with the aim of keeping the country beautiful and providing a positive impact. It’s important to us to leave the areas in which we operate better than we found them.

Winstone Aggregates is committed to the concept of kaitiakitangi, or being excellent custodians of the planet for now and for generations to come by having a positive impact and leaving a measurable net environmental gain.

You don’t keep a business successful for nearly 150 years without caring about the communities in which you operate and understanding sustainability. Long-term growth and resilience is what we’re all about, and these can only be achieved by having integrity and exhibiting responsible behaviour. It’s key to our business.
