6.1 Plumbers, Gasfitters, and Drainlayers Act 2006 & Board Functions

PGD Act and statutory framework

The Plumbers, Gasfitters, and Drainlayers Act 2006 creates the occupational regime. Candidates should use the current consolidated Act, not an old section list. Amendments supporting self-certification and records of work have changed the structure, so historical summaries may have obsolete numbering or omit current duties.

Source hierarchy

Read the sources in this order:

1. the Act, which establishes restricted work, registration, licensing, discipline, the Board, and the Registrar;
2. regulations made under the Act;
3. current Gazette notices prescribing registration classes and competence standards;
4. Board policies, forms, and guidance that administer those powers; and
5. technical compliance documents governing the building work itself.

A Board guidance document can explain expected practice but cannot override the Act. A technical standard does not authorise an unlicensed person to do restricted work. Keep occupational authority and technical compliance as two separate questions.

Board and Registrar

The current Act establishes the Plumbers, Gasfitters, and Drainlayers Board in section 133, deals with membership in section 134, and provides for the Registrar in section 140. The Board’s functions include administering registration and licensing, setting or prescribing relevant requirements, dealing with competence and discipline, and protecting public health and safety within the statutory scheme. The Registrar carries out administrative functions assigned by the Act and the Board.

Do not learn obsolete claims that the Board is created by section 131 or that the Registrar is section 138. In an open-book examination, use the current consolidation and verify headings.

Restricted work and authority

Drainlaying within the Act’s restricted-work regime may be performed only by someone with the appropriate current authority or by a person lawfully working under supervision. Authority is limited by trade, registration class, practising-licence status, endorsements, exemptions, and conditions. A plumber’s licence does not automatically authorise drainlaying, and registration without a current practising licence does not by itself authorise work during a licensing period.

The certifying class is the highest registration class in the trade and carries responsibility for supervision. That does not mean a certifier may approve unseen work or accept work outside the licence scope. The supervisor must have enough involvement to ensure the work is done competently, safely, and compliantly.

Examination, registration, and licensing

Passing examination 9198 is an examination prerequisite on the New Zealand pathway. The Board’s current certifying-registration page also requires the relevant active practising licence to have been held for 24 months, or 730 days from issue, before the certifying pathway is completed. Passing is therefore not the same event as being registered.

After registration, a practitioner needs a current annual practising licence to work during the licensing period and must meet the Board’s renewal requirements. Check the current Board material for fees, declarations, CPD, competence conditions, and dates; do not rely on an invented permanent 14-point scheme.

Applying the framework

For any scenario, ask four questions. What work is proposed? Is it restricted? What authority does each person hold on that date? If supervision is used, is it lawful and adequate for that work and worker? Then ask the separate Building Act question: does the completed work comply with the building consent and Building Code?

Example: a trainee may perform restricted drainlaying only within the permitted pathway and under the required supervision. The fact that a consented drawing exists does not authorise the trainee. Conversely, a licensed certifying drainlayer still must follow the consent and code; occupational authority is not permission to depart from the design.

Keep evidence: current licence checks, supervision arrangements, instructions, inspections, tests, and records. Those records support competent practice but do not create authority that the Act withholds.

Independent source-check exercise

For 6.1 Plumbers, Gasfitters, and Drainlayers Act 2006 & Board Functions, practise answering from evidence rather than recall. Write the controlling source, its edition or effective date, its scope, and the exact paragraph, table, figure, or manufacturer instruction that supports the decision. Then state the site inputs that can change the result. In this section those inputs include The Act, regulations, current Gazette registration notice, and Board policies have different legal functions and must be read in hierarchy.; The Board prescribes registration and licensing matters, while the Registrar performs statutory administrative functions.; Restricted drainlaying must be done by an authorised person or under lawful supervision within the person’s class and conditions..

Build a four-column check: proposed condition, source requirement, evidence observed, and action. Test the answer with one changed assumption. A different pipe size, discharge-unit load, ground condition, licence status, authority, compliance path, or consent condition may produce a different result. If it does, explain why; if it does not, show which requirement remains controlling.

Finish with a field-verification plan. Name what must be inspected before concealment, what instrument or record demonstrates it, who has authority to accept a change, and what appears on the as-built or completion file. This exercise turns an open-book fact into certifying-level judgement. It also exposes accidental mixing of standards: if the source for a dimension differs from the source for the test or approval, either return to one complete compliance path or document the proposal as an Alternative Solution. Do not promote an example value into a national rule.
