Neighbour Disputes in New Zealand — What the Law Says
Disputes between neighbours are among the most common civil law problems in New Zealand. Whether it's a fence you can't agree on, tree branches over your roof, a barking dog at midnight, or a boundary line nobody can find, New Zealand law gives you a clear set of rights and a range of low-cost ways to resolve the issue — often without going anywhere near a court.
Fencing — the Fencing Act 1978
The Fencing Act 1978 is the main law governing the construction, maintenance, and cost of boundary fences between private properties.
Who Pays?
Under the Act, owners of adjoining properties share the cost of an adequate fence equally — 50/50. "Adequate" means a fence that is reasonably appropriate for the locality, taking into account what neighbouring properties use the land for. A basic post-and-rail farm fence may be adequate in a rural area; a 1.8 m timber paling fence may be standard in a suburban neighbourhood.
The Fencing Notice Process
Before starting any work, you must serve a fencing notice on your neighbour. The notice must:
Your neighbour may then:
If you carry out urgent fencing work (to prevent an immediate hazard), you can still recover your neighbour's half — but you must notify them afterwards as soon as reasonably practicable.
Exceptions — When the 50/50 Rule Does Not Apply
| Situation | Rule |
|---|---|
| One owner's animals or activities caused the damage | That owner pays the extra cost |
| The fence only benefits one owner (e.g. a pool fence) | That owner pays the additional cost of the higher standard |
| Urban council has a different local standard | Local rules apply |
| Crown land, some reserves, railway land | Fencing Act may not apply |
Trees — Overhanging Branches and Encroaching Roots
New Zealand has no single "tree law." Your rights depend on the type of interference:
Cutting Back to the Boundary
At common law, you have the right to cut branches and roots that cross the legal boundary into your property — but only up to the boundary line. You:
When Cutting Is Not Enough — Nuisance Claims
If a tree causes ongoing, substantial interference (blocked gutters, cracked foundations, persistent leaf fall blocking drainage), you may have a claim in private nuisance under the common law. The test is whether the interference is unreasonable in the context of the neighbourhood. You would need to:
Resource Management Act and Heritage Trees
Some trees are protected under the Resource Management Act 1991 through district plan rules or heritage protection — you cannot prune or remove them without resource consent. Check your local council's district plan before touching any tree that looks mature or significant.
Noise — Your Rights and the Council's Role
Excessive noise is covered primarily by the Resource Management Act 1991 (RMA) and local district/city council bylaws.
Calling Noise Control
Every council in New Zealand runs a 24-hour noise control service. If your neighbour's noise is excessive — a party at 2 am, a barking dog, power tools on a Sunday morning — you can call:
A noise control officer can attend and issue a noise direction requiring the noise to stop immediately. Breaching a noise direction is an offence with fines up to $10,000 for individuals.
Excessive Noise — What "Excessive" Means
The RMA defines excessive noise as noise that is unreasonable or unnecessary in the context of the neighbourhood. There is no universal "11 pm rule" nationwide — it depends on zoning and local bylaws — but in practice councils treat late-night noise differently to daytime noise.
Persistent Noise — Further Options
| Escalation Option | When to Use |
|---|---|
| Council infringement notice | After repeated noise control visits |
| Disputes Tribunal claim | If noise causes you measurable loss (e.g. property damage, medical costs) |
| Environment Court | For ongoing, serious breaches of RMA noise standards |
| Council enforcement action | For commercial or construction noise exceeding permitted levels |
Boundary Disputes — Finding the Legal Line
If you and your neighbour disagree about where the boundary is, the legal line is determined by the survey plan registered with Toitū Te Whenua — Land Information New Zealand (LINZ), not by fences, hedges, or oral histories.
Step 1 — Get the Survey Plan
Search the certificate of title for your property at toitutewhenu.govt.nz. The deposited survey plan (DP) shows the legal boundary with measurements and bearing marks.
Step 2 — Commission a Cadastral Survey
If the plan alone does not resolve the dispute, engage a licensed cadastral surveyor (find one at nzis.org.nz) to locate and peg the legal boundary on the ground. This is the definitive method. Costs typically range from $1,500–$5,000+ depending on complexity.
Step 3 — Encroachments and the Property Law Act
If a building, fence, or structure encroaches over the boundary, the Property Law Act 2007 (s 327–333) gives the court power to:
Encroachment claims go to the District Court or High Court depending on the value involved.
