Q&A's: Who can you complain about?

The Board runs an independent, fair process for dealing with complaints about the conduct of plumbers, gasfitters, and drainlayers.

This process applies to the following people:

  • registered plumbers, gasfitters, or drainlayers
  • unauthorised people.

See the law on complaints and discipline in relation to plumbers, gasfitters, and drainlayers below:

Sanitary plumbing, gasfitting and drainlaying are regulated industries in New Zealand and it’s illegal for anyone to do this work unless they are authorised by the Board.

  • The Board also considers complaints about persons carrying out restricted sanitary plumbing, gasfitting and/or drainlaying when they are not registered, licensed or authorised to carry out that work.

Making a complaint

The checklist

  • The Board recommends that, before making a complaint, people try to resolve any issues by talking to the relevant plumber, gasfitter or drainlayer directly.
  • Problems are often resolved quickly and effectively in this way.
