Removing a tree that sits close to your fence is definitely doable, but it requires careful planning to avoid damaging the fence, injuring yourself, or falling foul of local council rules. In many cases, the safest and most cost-effective option is to hire a qualified arborist — especially when the tree is large or leaning toward the fence.
Check Council Rules Before You Touch Anything
Before you pick up a chainsaw, check whether your tree is protected. Many New Zealand councils have District Plan rules that restrict or prohibit the removal of certain trees — particularly large natives, trees in notable tree schedules, or trees within specific zones. Removing a protected tree without consent can result in significant fines.
Contact your local council's planning or resource consent team and ask:
- Is the tree listed on the notable or protected tree schedule?
- Does my property fall within a zone that restricts tree removal?
- Do I need a resource consent or tree removal permit?
You can also check your council's District Plan online. Rules vary significantly between councils, so never assume — always confirm directly.
Talk to Your Neighbour First
If the tree is on or near the boundary, or if its roots and canopy extend over the fence, your neighbour may have a legal interest in what happens to it. Under the Property Law Act 2007, neighbours have rights around overhanging branches and encroaching roots, but removing a shared or boundary tree without agreement can lead to disputes.
- If the tree is entirely on your property, you generally have the right to remove it (subject to council rules).
- If it straddles the boundary, both parties typically need to agree.
- If it's on your neighbour's property but overhanging your fence, you may be able to trim branches to the boundary line — but removing the whole tree is not your call.
When in doubt, get any agreements in writing before work begins.
Assess the Risk to Your Fence
Before removal, take a close look at the tree's relationship with the fence:
- Root systems — Tree roots can run under and lift fence posts and footings. Cutting roots carelessly can destabilise the tree or damage the fence foundation.
- Lean and weight distribution — A tree leaning toward the fence will naturally want to fall that way. Controlling the fall direction is critical.
- Canopy spread — Wide branches overhanging the fence can catch and pull it down if felled incorrectly.
- Fence type — Timber paling fences are more vulnerable to impact than concrete block walls, but any fence can be damaged by a poorly controlled fell.
For trees with a trunk diameter greater than about 200 mm or any tree that is leaning toward the fence, seriously consider hiring a professional.
Safe DIY Removal for Small Trees
For small trees (generally under 4–5 metres tall with a trunk you can comfortably wrap one hand around), a careful homeowner may be able to manage removal safely. Here's a general process:
Step 1 – Gather the right gear
At minimum you'll need: safety glasses, a hard hat, cut-resistant gloves, steel-capped boots, and hearing protection if using a chainsaw. WorkSafe NZ has guidance on personal protective equipment for tree work.
Step 2 – Plan your fell direction
Identify a clear fall zone away from the fence, structures, and people. Ensure bystanders are well clear — at least twice the tree's height away.
Step 3 – Use a rope for control
Tie a rope high on the trunk and have a helper apply gentle tension in the desired fall direction. This helps guide the tree away from the fence.
Step 4 – Make your cuts carefully
For chainsaw use, follow the standard notch-and-back-cut technique. If you're not experienced with a chainsaw, use a handsaw for smaller trunks or hire a professional. Chainsaws are a leading cause of serious injury in DIY tree work.
Step 5 – Deal with the stump
Once the tree is down, you can leave the stump to rot, grind it out (stump grinders can be hired from Bunnings or Mitre 10), or treat it with a stump-kill product to prevent regrowth.
Protecting the Fence During Removal
- Lay old carpet, plywood, or rubber matting along the top of the fence to cushion any accidental contact from branches.
- Remove fence panels temporarily if the tree must fall close to that line — it's much cheaper to re-fix a panel than replace a whole fence run.
- Work in sections (limbing from the bottom up) rather than felling the whole tree in one go when space is tight.
When to Call a Professional
Tree removal near a fence is one of those jobs where the cost of a qualified arborist is almost always worth it. You should definitely call a professional if:
- The tree is large (trunk over 200 mm diameter) or tall (over 5 metres).
- The tree is leaning toward the fence or a structure.
- The tree is dead, diseased, or structurally compromised — these are unpredictable.
- There are power lines anywhere near the canopy. Working near lines is extremely dangerous and may require your lines company to be involved.
- You're unsure about council rules — a good arborist will know local requirements.
- The job requires climbing or rigging to remove sections piece by piece.
A qualified NZ arborist will have the training, equipment, and insurance to do the job safely and protect your fence in the process. You can find licensed local arborists on tradedirectory.co.nz.
