Current risk requirements

New Zealand’s current requirements are based on the general duties of the Health and Safety at Work Act

Current measures taken by the regulator (WorkSafe) and industries that work with materials containing crystalline silica are premised on the existence of the general duties on businesses and workers under the Health and Safety at Work Act 2015 (HSW Act).[1] These duties require Persons conducting a business or undertaking (PCBUs) to eliminate, or use controls to minimise, worker exposure to risks, including from RCS.[2]

PCBUs must complete a risk assessment and review controls before starting work using engineered stone, and:

  • eliminate risks that arise from its work so far as is reasonably practicable, or
  • minimise risks so far as is reasonably practicable.

In most instances when working with sources of RCS (including engineered stone), this will mean making use of wet-working control measures, dust control measures, and Personal Protective Equipment (PPE).[3]

Several initiatives have been established to encourage businesses to improve their risk management practices.

  • WorkSafe has:
    • conducted inspections in workplaces fabricating engineered stone since 2019
    • published information for businesses and workers on RCS and silicosis, and
    • reduced the workplace exposure standard for RCS in 2019 and again in 2023.[4]
  • The Accident Compensation Corporation (ACC), Ministry of Health, and WorkSafe have established the Accelerated Silicosis Assessment Pathway (ASAP) to enable eligible workers to have their health checked.
  • The New Zealand Engineered Stone Advisory Group (NZESAG) has developed and implemented a voluntary industry accreditation scheme for engineered stone businesses, with support from ACC.[5]
