Delivering consistency of health and safety standards in the construction industry.

Raising the standards of Health and Safety in Construction

CHASNZ is an accredited charitable trust that has been developed to deliver a unified voice and to raise the standard of health and safety across the whole of the construction industry.

We want ALL construction workers to go home safe and well at the end of every day and we aim to help create a stepchange in the health and safety culture and performance in the next five years.  We can achieve this by working with industry to identify and provide guidance on best practice health and safety.

We are fortunate to have a high calibre Board who will act as ‘Brand Champions’ for each key sector of construction, providing inspirational leadership to enable better involvement and connection within the industry. 

This will allow us to establish consistent, easy to engage, health and safety systems that are at the heart of business culture. But it doesn’t stop there, we will continuously review and make improvements to the health and safety standards in the construction industry.
