Diving Industry Advisory Group

This page provides information about the Diving Industry Advisory Group and DIAG’s notices to the occupational diving industry.

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 (who provide secretariat services). 

DIAG’s primary purpose is to identify and reduce incidences of preventable injury through improved communications between the occupational diving sector and the regulator. Together, we and DIAG drive the adherence to good practice by the industry.

If you wish to contact DIAG directly or raise an occupational diving matter with them contact DIAG@worksafe.govt.nz.
