The Bill creates an opt‑in self‑certification pathway for qualified plumbers and drainlayers. The Plumbers, Gasfitters, and Drainlayers Board may endorse individuals who meet prescribed minimum standards; endorsed practitioners can issue a statutory certificate of compliance for defined, low‑risk plumbing and drainlaying work instead of undergoing a building consent authority (BCA) inspection.
Those certificates must be lodged on a public register and accepted by BCAs as proof of compliance, and BCAs are shielded from civil liability when they rely in good faith on such certificates.
This is designed to reduce inspection steps and speed house builds. At the same time the Bill creates a new oversight architecture: endorsement criteria and conditions, mandatory filing within tight timeframes, audit and competence‑review powers for the Board, increased penalties for false declarations, a levy to fund audits, and a monitoring role for the chief executive of MBIE.
Those implementation choices concentrate responsibility on practitioners and the Board — and create practical questions about enforcement capacity, regulatory calibration, and consumer recourse that will arise when regulations define the scope of ‘self‑certifiable’ work.
At a Glance
What It Does
The Bill lets the Board endorse individual plumbers and drainlayers to self‑certify specified, low‑risk plumbing and drainlaying work by issuing a prescribed certificate of compliance. Endorsed practitioners must lodge certificates and supporting documents on a publicly searchable register and may be audited by the Board; BCAs must accept those certificates when they relate to self‑certifiable work.
Who It Affects
Endorsed plumbers and drainlayers (new endorsement, compliance, and reporting duties); building consent authorities (fewer routine inspections but new record and verification flows); homeowners, developers and builders (faster consenting for eligible work and shifted reliance on practitioner certificates); the Plumbers, Gasfitters, and Drainlayers Board and MBIE (new monitoring, audit and administrative responsibilities).
Why It Matters
It changes where assurance sits in the consenting chain: from routine BCA inspection to practitioner declaration plus regulator audit. That can shorten delivery timelines for housing projects, but it also depends on the Board’s ability to set robust entry standards, run effective audits, and enforce sanctions — all funded in part by a levy on endorsed practitioners.

What This Bill Actually Does
The Bill creates a formal endorsement that sits on a plumber’s or drainlayer’s practising licence. To receive endorsement an applicant must meet minimum standards the Board prescribes (technical competency, experience, business and administrative practices, and capacity to meet potential civil liability), complete the application process, and pay any fee.
Endorsements last up to three years and are renewable through a defined application window; the Board may impose terms and conditions on an individual endorsement, including limits on the kinds of work the person may self‑certify.
When endorsed practitioners perform ‘self‑certifiable’ plumbing or drainlaying work (a scope to be set later by regulation), they may issue a certificate of compliance if the work was carried out in accordance with the applicable building consent. That certificate must be in the form required by the Board, include prescribed information, and be lodged with the Board and given to the homeowner within 10 working days of completing the work.
The Board will hold a public, free‑to‑search register of certificates and supporting documents.Building consent authorities must accept a certificate of compliance as establishing that the covered work complies with the building consent and may not be sued for relying in good faith on such a certificate. BCAs retain discretion in cases where the original consent application did not rely on self‑certification.
The chief executive of MBIE is required to monitor how the new scheme affects building‑sector performance and to support the Board in standing it up.To police the scheme, the Board can conduct desktop audits of certificates and supporting documents, review an endorsed person’s competence at any time, and use the expanded disciplinary toolkit — including suspension or cancellation of endorsements and higher monetary penalties for false declarations. The Board may also impose an endorsement levy to fund audits and related activities.
Regulations will define which plumbing and drainlaying activities are eligible for self‑certification and must be limited to routine, non‑complex, low‑risk work.
The Five Things You Need to Know
The Act’s general commencement date is 30 June 2026, but key implementation provisions (including powers to set fees, levies, and MBIE implementation functions) come into force the day after Royal assent.
An approved self‑certifying plumber or drainlayer must lodge every certificate of compliance with the Board and provide a copy to the homeowner within 10 working days after the work is completed.
Endorsements may last up to three years; renewal applications cannot be made earlier than three months before expiry and the endorsement continues if a renewal application is pending.
The Board can audit any lodged certificate and supporting documents, may review an endorsed person’s competence without prior cause, and may impose a levy on all endorsed practitioners specifically to fund auditing.
Monetary penalties for false declarations and unendorsed claims have been doubled to $20,000, and failure to provide the certificate of compliance within the required timeframe is a disciplinary offence that can affect an endorsement.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Title and staggered commencement
The Act is titled and given a main commencement date of 30 June 2026, but it brings forward a limited set of implementation powers (fees, levies, MBIE support, and the Board’s ability to publish application forms and notices) to the day after Royal assent. That staggered start lets MBIE and the Board prepare the register, application forms, and notices before endorsements and self‑certification become operational.
How self‑certification plugs into the consenting and CCC process
The Building Act changes add definitions, require building consent applications to list intended approved self‑certifiers and include statutory declarations, and make a certificate of compliance a required attachment to an application for a code compliance certificate when the consent relied on self‑certification. Critically, BCAs must accept those certificates as establishing compliance for the covered plumbing work and are protected from civil proceedings when they rely on them in good faith, but BCAs may refuse to issue a CCC if an owner fails to supply the certificate.
Owner notification when self‑certifiers change
Owners must notify the BCA as soon as practicable when an endorsed plumber or drainlayer who will issue a certificate was not named in the consent application, and must report when listed self‑certifiers cease work or are replaced. The notification triggers obligations on BCAs and creates an administrative trail tying certificates to a specific consent and owner.
Endorsement framework on the Plumbers, Gasfitters, and Drainlayers register
The Bill adds a discrete endorsement process: application forms and fees prescribed by the Board, criteria to be set under its rule‑making power, and a referral path from the Registrar to the Board. The Board must notify applicants of decisions and enter endorsements on the practising licence register; endorsements may carry tailored terms and conditions (including limits on the work an individual may self‑certify) and can be refused, suspended, or cancelled under the Board’s disciplinary processes.
Certificates of compliance, public register, and audit powers
Endorsed practitioners may issue certificates for work meeting consent conditions and must file those certificates and prescribed supporting documents with the Board and homeowners within 10 working days. The Board must maintain a publicly searchable register of certificates and may conduct desktop audits to verify eligibility, scope, and whether the work met the Building Code and the building consent. Sections from the existing register framework apply, limiting how data is handled and aligning searches with privacy obligations.
Expanded enforcement, governance, and funding powers
The Bill extends the Board’s competence‑review powers to endorsements, aligns disciplinary remedies with registration and licensing processes, raises key monetary penalties from $10,000 to $20,000 for false declarations and related offences, and empowers the Board to require returns (including certificates) and to include endorsement data in its annual report. It also creates a specific levy power to fund auditing activities, with exemptions or waivers available by notice.
Delegated regulation, risk gate, and transitional rules
Regulations will define ‘self‑certifiable plumbing’ and ‘self‑certifiable drainlaying’ and prescribe certificate content; the Minister must be satisfied those activities are routine, non‑complex and low‑risk before recommending regulations. Transitional provisions limit the retrospective application of certificates to work started after the later of the Act’s commencement or the Board’s initial notices, and allow the chief executive to exercise implementation functions immediately after Royal assent to prepare systems and communications.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Homeowners and developers — shorter consenting and inspection timelines for eligible plumbing or drainlaying work, which can reduce delays in completing houses and handovers.
- Endorsed plumbers and drainlayers — market advantage and faster sign‑off for routine work because endorsed practitioners can substitute a certificate for an inspection, potentially improving cashflow and scheduling.
- Building consent authorities — lower inspection workload for routine plumbing work, allowing BCAs to prioritize higher‑risk aspects of a consent portfolio.
- Plumbers, Gasfitters, and Drainlayers Board — central role in quality assurance and a new revenue stream (endorsement fees and a levy) to fund monitoring and audits, increasing regulatory influence over professional standards.
Who Bears the Cost
- Endorsed practitioners — new administrative duties (timely filing, recordkeeping), ongoing audit exposure, potential levy payments, and elevated disciplinary and civil risk if certificates prove incorrect.
- Territorial authorities/BCAs — must accept certificates and keep certificate records for the life of the building, adding permanent record‑management obligations even if inspections decline.
- The Board and MBIE — must design standards, run endorsement and renewal processes, maintain a public register, conduct audits and competence reviews, and manage public communications and complaints, all requiring resourcing and operational capacity.
- Homeowners/consumers — shifted reliance onto practitioners’ declarations increases dependence on after‑the‑fact enforcement; affected owners may face remediation cost and delay if self‑certified work is defective and liability paths are complex.
Key Issues
The Core Tension
The central tension is between speeding the delivery of routine plumbing work by replacing inspections with practitioner certification and preserving public safety and consumer protection: faster approvals reduce BCA cost and project delay but increase reliance on endorsements, post‑issue audits and disciplinary sanctions — a trade‑off only as effective as the Board’s entry standards, audit intensity, and enforcement capacity.
The Bill substitutes proactive inspection with ex‑post assurance: certificates plus audits. That model saves time where work is genuinely routine, but its success depends on tight regulatory design (clear scope of self‑certifiable work, robust entry standards, prompt audits) and sufficient resourcing of the Board.
The levy lets the Board fund audits, but a levy set too low will leave the scheme under‑monitored; a levy set too high risks imposing disproportionate costs on small practitioners and pushing them out of the endorsement pool.
Several operational gaps are left to delegated instruments. Regulations will define eligible work, the certificate content, and supporting documents — decisions which will determine risk exposure but do not appear constrained by quantitative thresholds in the Bill.
The Board’s audit power is primarily desktop‑focussed; if systemic workmanship issues emerge, the Bill relies on existing disciplinary and civil remedies rather than mandating on‑site verification frequency or proactive sampling targets. Finally, shifting civil liability away from BCAs toward practitioners and owners simplifies BCA risk management but raises practical questions about insurance, remediation funding, and whether homeowners will have timely and effective remedies when certificates prove incorrect.
