The PCBU establishes a health and safety committee for the business or undertaking or part of it within 2 months of a request by an HSR for a work group at the workplace or by 5 or more workers there, or when and as the regulations require; it may also establish one on its own initiative. The constitution is agreed with the workers; an HSR who consents is a member (or, where there are several, those they choose); at least half the members are workers not nominated by the PCBU; if agreement is not reached in reasonable time, an inspector may decide.
