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

Raising the standards of Health and Safety in Construction

Construction Health and Safety New Zealand (CHASNZ), a charitable trust developed in 2018 with the objective of improving the lives of construction workers by raising the standard of health and safety culture and performance across the construction industry in New Zealand.
The CHASNZ Board, comprises Independent Chair, Roger McRae and senior industry leaders from across all construction sectors, working together they are the collective voice for industry addressing the need for a sustainable change across the sector, identifying areas of risk, providing guidance on best practice health and safety and ensuring health and safety is an intrinsic part of doing better business.

Over the past five years injury claims have steadily increased and sadly 29 people have died on our building sites, making construction sites the deadliest workplaces in New Zealand.

This increasing injury rate is a key reason why ACC has entered into a five-year partnership with CHASNZ allowing an increase in efforts across health and safety promotion and protection initiatives, enabling a reduction in the harm caused by occupational illness and injury in the construction sector.

We want ALL our construction workers to go home safe and well at the end of each day.
