Market position

The Plumbers, Gasfitters and Drainlayers Board (PGDB) registers and licenses plumbers, gasfitters and drainlayers in New Zealand under the Plumbers, Gasfitters, and Drainlayers Act 2006, sets minimum competence standards, and handles complaints, discipline and court prosecutions of people doing unauthorised work. The Board says it is a not-for-profit body funded by fees, with ten ministerially appointed members representing the trade and the public. Registration classes include certifying, plumber, gasfitter or drainlayer, and restricted, plus limited certificates for trainees.

New Zealand-specific note

Customers can check a tradesperson's licence on the PGDB public register, and practitioners can show their licence in the PGDB app or on a physical card. Homeowners may only do limited DIY work, such as replacing taps or clearing a blocked drain without altering pipes. From 7 September 2026, certifying plumbers and drainlayers with a self-certification endorsement can sign off their own consented work instead of an inspection by the building consent authority.

Why this matters for New Zealand trades

Only EWRB-registered and licensed workers can carry out or supervise prescribed electrical work, with the practising licence renewed every 2 years; the PGDB registers and licenses plumbers, gasfitters and drainlayers and prosecutes unauthorised work; and Restricted Building Work on homes must be done or supervised by a Licensed Building Practitioner. WorkSafe enforces the Health and Safety at Work Act 2015 and says amendments take effect on 1 April 2027. The payroll tools listed here file payday information with Inland Revenue, and some act as PAYE intermediaries that pay PAYE to Inland Revenue for you. Master Builders and Master Plumbers membership is voluntary and does not replace licensing.

New Zealand trades vendor selection is shaped by registration and licensing (the EWRB for electrical workers, the PGDB for plumbers, gasfitters and drainlayers, and the LBP scheme for Restricted Building Work on homes), payday filing with Inland Revenue, KiwiSaver deductions, Holidays Act leave calculations, 15% GST, and health and safety duties under the Health and Safety at Work Act 2015.
