In New Zealand, concreter and concrete layer are simply two names for the same trade. Both terms describe a tradesperson who places, levels, and finishes concrete for driveways, floors, paths, foundations, and other structures. The terminology varies by region and by who you're talking to — builders often say "concreter," while some suppliers and older trade documents use "concrete layer" — but there is no meaningful difference in what the person actually does.
What Does a Concreter (or Concrete Layer) Actually Do?
A concreter handles the full process of getting concrete from the mixer to its finished state. Their work typically includes:
- Preparing the sub-base — excavating, compacting the ground, and laying a suitable base (often AP20 or AP40 crushed aggregate) to the correct depth and level
- Setting up formwork — building timber or steel frames that hold the wet concrete in shape until it sets
- Placing reinforcement — laying steel mesh or rebar where required by design or the NZ Building Code
- Ordering and pouring concrete — coordinating with a ready-mix supplier and placing the concrete efficiently before it begins to set
- Screeding and floating — levelling and smoothing the surface to the correct falls and finish
- Applying surface finishes — broom finish, exposed aggregate, trowel finish, or stamped patterns
- Cutting control joints — sawcutting or tooling joints to control where cracking occurs
- Curing — applying curing compounds or wet hessian to slow moisture loss and achieve full strength
Why Are There Two Different Terms?
The term concrete layer is more common in formal trade documentation, some older Standards New Zealand publications, and among certain suppliers. Concreter is the everyday term most New Zealanders use and is the label you'll see on most trade directories, job boards, and business listings. Neither term is wrong — they simply reflect regional habit and the evolution of trade language over time.
In Australia, "concreter" is almost universal, and because NZ and Australian trade culture overlap significantly, that term has become dominant here too.
Is Concreting a Licensed or Regulated Trade in NZ?
Unlike electrical or plumbing work, concreting is not a licensed trade in New Zealand. There is no registration board or legal requirement for a concreter to hold a specific licence to pour a driveway or lay a floor slab. However, this does not mean anyone can do it well — concrete work requires real skill, the right equipment, and knowledge of NZ standards.
For structural concrete work (such as foundations, retaining walls over certain heights, or concrete that forms part of a building's structure), a building consent may be required from your local council. Work done under consent must comply with the NZ Building Code and relevant standards such as NZS 3109 (Concrete Construction). Always check with your council before starting any structural concrete project.
Some concrete work falls under Schedule 1 of the Building Act as exempt from consent — for example, small garden paths or non-structural slabs — but the rules depend on your specific situation and council. Confirm with your local council before assuming consent is not needed.
If your project involves a Licensed Building Practitioner (LBP), they may be required to carry out or supervise restricted building work. You can verify LBP registration at Licensed Building Practitioners.
What Skills Should a Good Concreter Have?
When hiring a concreter in NZ, look for someone who:
- Has solid experience with the type of work you need (residential slabs differ from commercial floors)
- Understands local soil conditions and drainage requirements
- Can advise on the correct concrete mix design (strength grade, slump, and admixtures) for your application
- Knows how to achieve the correct falls to drain — important in NZ's wet climate to avoid pooling water
- Is familiar with BRANZ good practice guides relevant to concrete
- Carries appropriate public liability insurance
| Term | Meaning | Common Usage |
|---|---|---|
| Concreter | Tradesperson who places and finishes concrete | Everyday NZ usage, trade directories |
| Concrete layer | Same tradesperson, same work | Formal documents, some suppliers |
Can a Homeowner Do Their Own Concreting?
For small, non-structural projects like a garden path or a small pad, a capable DIYer can attempt concreting. However, concrete is unforgiving — it sets quickly, and mistakes in levelling, finishing, or curing are difficult or impossible to fix once the concrete hardens. Hiring a professional is strongly recommended for driveways, house slabs, garage floors, and anything structural.
When to Call a Professional
You should hire a qualified concreter when:
- The slab or structure requires a building consent
- The area is larger than a small garden path or pad
- The concrete needs to bear vehicle loads (driveways, garage floors)
- The work involves reinforced concrete or ties into existing foundations
- You need a specific decorative finish such as exposed aggregate or polished concrete
- The ground conditions are poor, sloped, or require drainage design
A professional concreter will also have access to the right tools — power screeds, bull floats, trowelling machines, and concrete saws — that make a significant difference to the final result.
