Unlike plumbing or electrical work, fencing is not a licensed or registered trade in New Zealand. There is no government body that certifies or registers fencers, and no legal requirement for a fencer to hold a trade licence to build a standard residential fence. That said, there are still important rules — around building consents, pool fencing safety, and neighbour obligations — that both homeowners and fencers need to follow.
No Licensing Requirement for General Fencing
Any person or business can legally offer fencing services in New Zealand without holding a formal trade qualification or registration. This means the barrier to entry is low, and the quality of tradespeople in the market can vary considerably. When hiring a fencer, it pays to do your homework.
Look for fencers who:
- Have a solid portfolio of completed work and verifiable references
- Carry public liability insurance (ask to see a current certificate)
- Are familiar with the relevant NZ Building Code requirements
- Provide a written quote and contract before starting work

When a Building Consent May Be Required
While many residential fences are exempt from building consent under Schedule 1 of the Building Act 2004, this is not always the case. As a general guide:
| Fence type | Consent likely needed? |
|---|---|
| Standard boundary fence under 2.5 m | Usually exempt |
| Retaining wall over 1.5 m (or near a boundary) | Often required |
| Fence on a sloped or unstable site | Check with council |
| Pool/spa barrier fence | Yes — specific rules apply |
| Fence in a heritage or special character zone | Check with council |
Always confirm with your local council before starting work, as exemptions can depend on your specific site, zoning, and local district plan rules. The MBIE Building Performance website has detailed guidance on Schedule 1 exemptions and when consent is required.
Pool and Spa Fencing — Strict Legal Requirements
This is where fencing rules get serious. Pool and spa barriers are governed by the Building Act 2004 and NZS 8500:2006, and all swimming pools and spa pools that can hold water deeper than 400 mm must have a compliant barrier. These rules are enforced by your local council, which must inspect and certify pool fences.
Key requirements include:
- Minimum fence height of 1.2 m (measured on the outside)
- No climbable footholds within 900 mm of the top
- Self-closing, self-latching gates that open away from the pool
- No gaps that a 100 mm sphere could pass through
Because pool fencing must meet a building consent and inspection process, it's strongly advisable to hire a fencer who has experience with pool barrier compliance. Errors can result in council enforcement action and, more importantly, serious safety risks. MBIE Building Performance has up-to-date information on pool barrier requirements.
The Fencing Act 1978 — Neighbour Obligations
If your fence is on or near a shared boundary, the Fencing Act 1978 comes into play. This law sets out how costs for a boundary fence are shared between neighbours (generally 50/50 for a standard fence), and the process for serving a fencing notice if a neighbour is reluctant to contribute.
Key points:
- You must serve a formal fencing notice before starting work if you want to recover costs from your neighbour
- Neighbours have 21 days to respond
- Disputes can be taken to the Disputes Tribunal

Health and Safety on the Job
Even though fencing is unregulated as a trade, health and safety obligations still apply under the Health and Safety at Work Act 2015. If you're hiring a fencer, they are responsible for managing hazards on site — including working near power lines, handling treated timber (which can contain preservatives like copper azole or LOSP), and safe use of post-hole borers and power tools.
Homeowners who act as a PCBU (Person Conducting a Business or Undertaking) when hiring contractors also have duties. WorkSafe NZ has clear guidance on what this means in practice.
Treated Timber and Material Choices
Most NZ fencing uses H4 treated pine for posts in ground contact, in line with BRANZ guidance and NZS 3602 timber treatment standards. A knowledgeable fencer will specify the correct treatment level for your conditions. Timber and hardware are widely available from suppliers like Mitre 10, Bunnings, and PlaceMakers.
When to Call a Professional
While a competent DIYer can build a simple boundary fence, you should strongly consider hiring a professional fencer when:
- The fence involves a pool or spa barrier (council inspection required)
- You need a building consent (e.g., retaining walls or large structures)
- The site has difficult terrain, unstable ground, or proximity to services
- You want a written guarantee and insurance cover for the work
- There is a neighbour dispute involved
A qualified, experienced fencer will save you time, ensure compliance, and give you peace of mind. Find trusted local fencers on tradedirectory.co.nz.
