Water Management Act 2000

A person must not do any kind of plumbing work unless the person—

holds an endorsed contractor licence or a supervisor certificate under the Home Building Act 1989 that authorises the holder to do that kind of work, or

does the work under the immediate supervision of the holder of such a licence or certificate, or

holds a tradesperson certificate under the Home Building Act 1989 that authorises the holder to do that kind of work under supervision, and does the work under the general supervision of the holder of a licence or certificate referred to in paragraph (a).

The regulations may make provision about the carrying out of plumbing work, including the following—

the regulation and prohibition of plumbing work,

permits granted by water supply authorities for the carrying out of plumbing work,

the standards for and supervision of plumbing work,

directions given by water supply authorities to persons about plumbing work,

exemptions granted by water supply authorities to a person or class of persons, with or without conditions, from requirements under the regulations in relation to plumbing work.

If a requirement about plumbing work imposed by the regulations is inconsistent with a requirement imposed by the Plumbing and Drainage Act 2011 or the regulations under that Act about the same work, that Act and the regulations under that Act prevail to the extent of the inconsistency.
