What a Handyman Can (and Can't) Legally Do in New Zealand

The legal line between a handyman and a licensed tradesperson in New Zealand isn't about how hard the job is. It's about who's paying. A homeowner can legally do more electrical, plumbing and building work on their own house than most people realise, provided they do it themselves, unpaid. The moment you pay someone else to do that same job, the exemption that let you do it yourself disappears, even if the person you hired has done the exact task a hundred times. That distinction is the part most hiring guides skip, and it's the one that determines whether your handyman is working within the law.
The rule behind every trade restriction
New Zealand regulates four kinds of home work separately: electrical work, gasfitting, plumbing and drainlaying, and what the Building Act calls restricted building work, meaning structural carpentry, roofing, foundations and weathertightness. Each has its own board and its own Act. But they share one structure. An owner-occupier can do a defined slice of minor work on the home they live in, unpaid. Nobody else can, unless they hold the relevant licence. Not a builder's mate. Not a handyman who's done this exact job fifty times. Pay someone, and the work has to be done, or in some cases signed off, by a person registered for that specific trade.
That's the Electricity Act 1992 and the Electricity (Safety) Regulations 2010 for wiring, the Plumbers, Gasfitters and Drainlayers Act 2006 for pipes and gas, and the Building Act 2004 for restricted building work. Different boards, same shape.
Electrical: the specific list, and where it stops
WorkSafe publishes exactly what a homeowner can do to the wiring in their own house, without an electrician, as long as nobody pays them for it. You can replace switches, socket outlets, light fittings, ceiling roses and cord-grip lampholders. You can replace fuse links, connect or disconnect fixed appliances, and relocate an existing switch or outlet if it's wired with tough plastic-sheathed cable. You can even install or alter a sub-circuit yourself, provided a registered electrical inspector tests and connects it before it's used.
That's a longer list than most people expect, and it's also exactly where it ends. Touch the switchboard beyond fuse links, connect new wiring to the supply yourself, or do any of this for someone else, paid or not, and the work needs to go to someone registered with the Electrical Workers Registration Board (EWRB). MBIE's investigations team has told RNZ they're seeing a rise in unlicensed electrical work, usually people trying to save money or get a job done faster than a registered electrician could get to it. A handyman quietly doing this kind of work instead of turning it away is part of that pattern, not an exception to it.
Gasfitting: the narrowest exemption of all
Gas has a DIY allowance, but it's smaller than most people assume, and the regulator itself doesn't recommend using it. The Plumbers, Gasfitters and Drainlayers Board's own consumer guidance limits homeowner DIY to portable gas appliances with the bottle attached: a barbecue, a cabinet heater, a patio heater. Even for that, the Board's advice is to get a gasfitter to do it anyway. Anything connected to a fixed gas supply, including installing a gas appliance you bought yourself, has to be done by someone authorised under the Plumbers, Gasfitters and Drainlayers Act.
The reason shows up in enforcement records rather than in a generic safety warning. A Bay of Plenty builder was fined after illegally installing a gas cooktop, a fixed installation, not a portable barbecue. When a properly licensed gasfitter checked the job afterward, they found a significant leak in a pipe running through an upstairs wall cavity, the kind of space that can fill with gas until a spark from an ordinary light switch is enough to ignite it. That's the specific failure mode the licensing requirement exists to prevent.
Plumbing and drainage sit in the middle
Plumbing has its own version of the electrical exemption, and it's spelled out directly in the Board's guidance for consumers. As the owner-occupier, you can install appliances like a dishwasher or washing machine, and replace or repair taps, ball cocks and plugs, without a licence, on your own home. You can also clear a blocked drain yourself, as long as you don't touch the inspection or ventilation pipe while doing it. Installing or replacing a toilet, shower or wastewater system, or any work on the actual pipes, is sanitary plumbing, and that needs someone registered with the Plumbers, Gasfitters and Drainlayers Board (PGDB), whether you're paying them or doing it yourself for someone else's house.
Restricted building work carries a fine for both sides
Carpentry, roofing, brick and block laying, external plastering and foundation work on a house fall under what the Building Act calls restricted building work: structural or weathertightness-critical work. This category has a sharper edge than the trade licences, because getting it wrong can fine both the person who did the work and the person who hired them.
Section 85 of the Building Act makes it an offence to carry out restricted building work without holding the right licence, punishable by a fine of up to $20,000. Section 86 makes it a separate offence to knowingly engage someone who isn't licensed to do that work, also up to $20,000. That second one is the part homeowners tend to miss. Hiring the wrong person for a structural job isn't only their legal problem. Insurers can compound this: if unlicensed or unconsented work later contributes to damage, a claim covering that damage can be declined, which is common enough that both the Insurance & Financial Services Ombudsman and Financial Services Complaints Ltd handle disputes over exactly this.
Not every deck or fence counts as restricted work. Low decks, pergolas and fences under 2.5 metres often don't need a building consent, and a deck with a fall height under 1.5 metres usually doesn't either. But consent-exempt and licence-exempt aren't the same test. Auckland Council is explicit that some consent-exempt work is still restricted building work if it affects the structure or weathertightness of the house. Check with council or a Licensed Building Practitioner before assuming a small deck is handyman work. The two rules don't automatically line up.
Where a handyman is exactly who you want
None of this makes a general handyman a fallback option. It defines their lane. Painting, gib patching and interior touch-ups, flatpack and fixture assembly, non-structural shelving and fencing repairs, gutter clearing, garden work, and general fix-it jobs around the house are all things a handyman can do well and legally, without either of you needing to check a register first. Most of what goes wrong in a house, a sticking door, a wobbly fence paling, a bathroom that needs regrouting, sits comfortably inside that lane. The trade licences only apply once a job touches wiring, gas, sanitary plumbing, or the structure and weatherproofing of the building.
Checking before you hire
All three boards keep a public register you can search by name before work starts, not after something goes wrong.
| Work type | Licensing body | Register |
|---|---|---|
| Electrical | Electrical Workers Registration Board (EWRB) | ewrb.govt.nz |
| Gasfitting, plumbing, drainlaying | Plumbers, Gasfitters and Drainlayers Board (PGDB) | pgdb.co.nz |
| Restricted building work | Licensed Building Practitioners scheme | lbp.govt.nz |
It takes less time than getting the quote did.
This is exactly why Servy separates general labour from the trades in the first place: the jobs listed there are the ones that don't need a registered tradesperson. For anything that touches wiring, gas, sanitary plumbing or the structure of the house, book someone who's licensed for it, and check the register first. Once you know the job legally is handyman work, the other question people worry about — cash job or invoice — changes less than you'd think.
