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.
