Role of WorkSafe

The role of WorkSafe in occupational diving is to act as the regulator for ensuring the safe operation of the occupational divers in New Zealand. We do this by:

  • assessing that applicants of Certificates of Competence meet the Health and Safety in Employment Regulations regarding occupational diving
  • working with the diving industry to provide good guidance and to improve occupational diving best practice

The Diving Industry Advisory Group

The Diving Industry Advisory Group (DIAG) represents each of the occupational diving sectors in New Zealand and is the conduit between these sectors, hyperbaric experts and WorkSafe New Zealand.

WorkSafe and DIAG work together to identify and reduce preventable injury through adherence to good practice by industry.
