Why checking a tiler matters in NZ
A good tiler does more than make a bathroom or kitchen look neat. Proper preparation, waterproofing, substrate checking and correct installation all affect whether the job lasts for years or starts lifting, cracking or leaking after the first winter.
In New Zealand, you also need to be careful about who is doing the work around wet areas. Tiling itself is not a separately licensed trade in the way plumbing or electrical work is, but parts of a tiling job may overlap with other regulated work, especially in bathrooms and showers. That means you should check not only skill and experience, but also whether the person understands the compliance side of the job.
Hiring carefully can help you avoid:
- failed waterproofing and water damage - tiles debonding because the substrate was not prepared properly - uneven falls in showers and around drains - delays if the work needs a consent or sign-off - insurance issues if an unqualified person has done regulated work
Is tiling a licensed trade in New Zealand?
No — there is no standalone national licence for tilers in NZ.
That said, a tiler may still need to work within regulations if the job involves:
- waterproofing a wet area - building work that affects the structure, substrate or layout - plumbing fixtures, waste outlets or drain connections - electrical work for heated floors, lights or underfloor systems
For example, if the project includes moving a shower waste, changing plumbing, or altering electrical wiring for heated towel rails or under-tile heating, those parts must be done by the appropriately licensed tradesperson. A tiler may coordinate the job, but cannot legally carry out restricted work unless they hold the right registration and licence for that work.
For homeowners, the key point is simple: a tiler may be perfectly competent at tiling, but that does not automatically cover plumbing, gasfitting, drainlaying, or electrical work.
Qualifications and memberships to look for
Because there is no mandatory tiler licence, you are mainly checking for proof of training, experience and good practice. Useful credentials include:
- **National Certificate or New Zealand Certificate in Tiling**: These show formal training, though the exact qualification may vary by provider and year. - **BCITO apprenticeship or trade training**: This is a strong sign the tiler has completed structured industry training. - **Waterproofing training**: Particularly important for bathrooms, laundries, balconies and showers. - **Manufacturer training**: If they use a specific waterproofing or tile adhesive system, manufacturer accreditation can be a plus. - **Industry memberships**: Membership of a trade association can be helpful, but it is not the same as a legal licence.
A qualified tiler should also be able to discuss:
- substrate preparation - movement joints and expansion joints - grout choice and sealing where relevant - waterproofing systems suitable for NZ conditions - falls to waste in showers and wet rooms - slip resistance for floors and outdoor areas
How to verify a tiler’s credentials
The best way to check is to ask for details early, then confirm them before work starts.
Ask for these documents
Request:
- copies or photos of qualifications - evidence of apprenticeship or trade training - references from recent NZ jobs - a current written quote - proof of public liability insurance - details of any subcontractors they use
If they claim to be licensed for plumbing or electrical work, ask for the relevant registration numbers and verify them directly.
Check the relevant NZ registers
Use official registers, not just a business website or social media page.
| Work type | Regulator / register | What to check | |---|---|---| | Plumbing, gasfitting, drainlaying | Plumbers, Gasfitters and Drainlayers Board (PGDB) | Registration and current practising licence | | Electrical work | Electrical Workers Registration Board (EWRB) | Registration and practising licence | | Building work that may need consent or restricted building work | Local council / Licensed Building Practitioners (LBP) | Whether the person is licensed for any restricted building work they claim to do | | Tiling skills / training | Training provider, BCITO, references | Qualifications, experience and completed jobs |
If you are unsure whether part of the job is restricted building work or needs a consent, contact your local council before work begins. Bathrooms, showers and wet areas can involve consent or compliance issues depending on the scope.
Verify insurance
Ask whether the tiler has:
- public liability insurance - cover for faulty workmanship, if offered - tools and vehicle insurance
Insurance is not a licence, but it matters if something goes wrong. In NZ, many reputable tradespeople will readily show proof.
Questions to ask before hiring
A genuine professional should answer these confidently and specifically:
- How many bathroom, kitchen or outdoor tiling jobs have you done in New Zealand? - Have you tiled over concrete, ply, fibre-cement sheet and existing tiles? - Who is responsible for waterproofing, and what system will you use? - Will you install movement joints where needed? - Have you worked with this tile format before, especially large-format tiles or mosaics? - Will you use a licensed plumber or electrician if the job needs one? - What warranty do you offer on labour? - What preparation is included in your quote?
Good signs include:
- they explain why a surface needs levelling or priming - they ask about tile supply, slip rating and grout colour - they talk about curing times and moisture control - they are clear about what is excluded from the quote
Red flags include:
- vague answers about waterproofing - pressure to pay a large deposit upfront - refusal to give references - no written quote - “mate’s rates” for work involving plumbing or electrical changes - claims that “consent is never needed” without checking the scope
What a proper NZ quote should include
Always compare at least two or three written quotes. The cheapest price is not always the best value, especially with waterproofing and wet areas.
A useful quote should spell out:
- labour and materials separately where possible - tile laying method and pattern - substrate preparation and any levelling - waterproofing scope and who is doing it - grout, silicone and movement joints - disposal of waste - start date and estimated duration - payment stages - warranty terms
Typical cost factors in NZ
Tiling prices vary a lot by region, tile type and site access. In many parts of NZ, labour costs are higher in busy periods or where trades are in short supply.
Costs can rise if the job involves:
- demolition or removal of existing tiles - uneven floors or walls - waterproofing a full bathroom - intricate patterns, mosaics or herringbone layouts - cutting around lots of fixtures - outdoor tiling that needs correct falls and weatherproof materials
If you are getting quotes in summer, be aware that experienced tilers often book out early for bathroom renovations and outdoor jobs. In wetter or colder months, drying times may be longer and some products may need extra care.
Why licensing and consent rules matter
Even though a tiler is not separately licensed, compliance still matters.
If the job touches restricted work, the person doing it must hold the right registration and licence. If building work requires consent, or if the project is part of a larger renovation, the work should match what the consent documents and plans allow.
This matters because:
- non-compliant work can be expensive to fix later - councils may ask for evidence if work is checked - insurers can question claims if the work was not done properly - poor waterproofing can create hidden damage that appears months later
A competent tiler should be comfortable working alongside other trades and following the correct process, not trying to do everything themselves.
Signs you are dealing with a genuine professional
Look for a tiler who:
- turns up on time for the quote - measures carefully and asks about the substrate - explains product choices clearly - provides references from recent NZ clients - has photos of completed work, including close-ups of corners and finish details - gives a realistic timeframe, not an overly optimistic promise - puts everything in writing
A good tiler will also tell you when something is outside their scope, such as plumbing, electrical work or structural changes.
Final checklist before you book
Before you sign anything, make sure you have:
- checked whether any plumbing, electrical or building consent issues apply - verified any claimed registrations on the relevant official register - seen qualifications or training evidence - confirmed insurance - received at least two or three written quotes - agreed the scope, materials, timing and warranty in writing
If the job is a bathroom or other wet area, be especially careful. Water damage is one of the most expensive mistakes to fix in a Kiwi home, and it is often preventable with the right person and the right process.
Taking a little extra time to check a tiler’s qualifications, experience and compliance can save you money, stress and repairs later. It is one of the smartest steps you can take before any renovation starts.
