Tree Disputes in New Zealand: Overhanging Branches, Roots and the Property Law Act 2007

If a neighbour's tree overhangs your section or its roots are pushing into your property, New Zealand law generally lets you cut the branches and roots back to the boundary yourself. If the tree is actually causing damage or serious interference, the Property Law Act 2007 sets out a separate process to apply to the District Court.

This is general information about New Zealand law, not legal advice. For your own situation, consult a lawyer or your local Community Law centre.

The basic rule: cut back to the boundary, nothing more

Under New Zealand common law, a property owner has a long-recognised right of "abatement": if a neighbour's tree branches or roots cross onto your land, you can cut them back yourself, without asking permission first. The right stops exactly at the boundary line between the two properties. You cannot go onto your neighbour's land, and you cannot cut back further than the point where the branch or root crosses onto your side.

This is a self-help remedy, not a right to make your neighbour do the work or pay for it, unless the tree is actually causing damage (see below). If the branches are simply overhanging without causing any harm, the usual position is that each owner deals with their own side of the boundary.

What happens to the branches, roots and fruit you cut off

Even though the branches were growing over your land, the tree itself, and everything that grows on it, still belongs to your neighbour. That includes any fruit, flowers, or foliage on the parts you trim off. The accepted practice is to offer the cuttings back to the tree's owner rather than keep, sell, or dispose of them as if they were yours.

Do not trespass, and do not kill the tree

The self-help right to trim comes with two firm limits. First, you cannot cross onto your neighbour's property to do the work, even if it would be easier to reach the branch or root from their side. Second, you cannot use a method, such as poisoning the roots, that is intended to kill the tree or that causes damage beyond what is needed to remove the encroaching growth. Trimming that is reasonable and confined to your own side of the boundary is unlikely to create liability even if it later turns out to have weakened or killed the tree, but deliberately targeting the tree to kill it is a different matter and can expose you to a claim from your neighbour.

Check for a notable or protected tree first

Before you cut anything, check whether the tree is listed as a notable or protected tree in your local council's district plan. Councils around New Zealand maintain registers of trees considered worth protecting for their size, age, species, or amenity value, and these are set out as schedules in each council's district plan. Minor trimming of a listed tree is often still permitted, but removal or more significant work on a protected tree generally requires a resource consent from the council, and there can be real penalties for cutting a protected tree without one. If you are not sure whether a tree is protected, check with your local council before doing any work, even work that would otherwise fall within the ordinary self-help right.

When self-help isn't enough: damage or undue interference

Self-help trimming is meant for ordinary overhanging growth. It is not designed for situations where a tree is actually causing damage, for example cracking a fence, driveway, or foundation, blocking underground drains or pipes, or seriously interfering with the reasonable use and enjoyment of your property. For that kind of dispute, the Property Law Act 2007 sets out a specific process, separate from the general self-help right, for dealing with trees that are causing damage or undue interference to a neighbouring property.

VERIFY: the precise statutory wording and section numbers of the Property Law Act 2007 tree provisions (commonly cited as sections 332 to 338) could not be confirmed directly from legislation.govt.nz in this session, because the site returns an HTTP 403 to automated fetches. Multiple secondary legal sources describe the same substantive test (damage, or undue interference with the use and enjoyment of the land), and this page states the rule at that level rather than asserting exact subsection numbers.

Applying to the District Court under the Property Law Act 2007

Where a tree is causing damage or undue interference and talking to your neighbour has not resolved it, you can apply to the District Court under the Property Law Act 2007 for an order requiring the tree's owner to trim or remove the tree, and, where relevant, to repair or contribute to the cost of repairing any damage the tree has caused. The court weighs factors such as the extent of the damage or interference, the value and character of the tree, and any public or amenity value it has, against the burden of the order on the tree's owner.

A court application is a more significant step than everyday trimming. It generally requires evidence of the damage or interference, and the person applying usually bears the cost of bringing the application. For that reason, most tree disputes between neighbours are resolved informally, or with written legal advice, well before a court application becomes necessary.

Frequently Asked Questions

Can I cut branches from my neighbour's tree that hang over my property?

Generally yes. You can trim overhanging branches and encroaching roots back to the boundary line yourself, without needing your neighbour's permission first, as long as you stay on your own side of the boundary.

Do I have to give the cut branches back to my neighbour?

The branches, roots, and any fruit or flowers on them remain the tree owner's property even after you cut them off. The usual practice is to offer the trimmings back rather than keep or dispose of them yourself.

Can I go onto my neighbour's property to trim their tree?

No. The right to cut back overhanging branches and roots stops at the boundary line. Going onto your neighbour's land to do the work is trespass.

What if the tree is listed as a protected or notable tree?

Check your council's district plan before doing any work. A tree listed as notable or protected generally needs a resource consent for anything beyond minor trimming, and removing or damaging one without consent can carry penalties.

What can I do if a neighbour's tree is actually damaging my property?

If the tree is causing damage, such as to a building, fence, or drains, or is causing undue interference with your land, you can apply to the District Court under the Property Law Act 2007 for an order requiring the tree's owner to trim or remove it and address the damage.

Is applying to the District Court the first step in a tree dispute?

No. A court application is generally a last resort after talking to the neighbour, and often legal advice, has not resolved the problem. Ordinary overhanging branches or roots that are not causing damage are usually dealt with through the self-help trimming right instead.
