Neighbour's Trees Overhanging Your Property? Here's What You Can Do
Your neighbour's tree might look great from their side of the fence, but when branches start hanging over your roof, blocking sunlight or taking over your garden, it's a different story.
Neighbours trees overhanging your property are a common frustration for homeowners across Christchurch and Canterbury, particularly in established neighbourhoods where mature trees have grown well beyond their original boundaries. The good news is that you don't necessarily need to remove the entire tree to solve the problem.
Professional tree pruning, crown reduction and selective branch removal can often make a significant difference while keeping the tree healthy.
What Can You Do About Overhanging Tree Branches?
If your neighbour's tree is growing over your boundary, the first step is to work out exactly what's causing the problem. Are branches brushing against your roof? Blocking sunlight? Hanging over a driveway? Or simply taking up more space than you'd like?
Different problems require different solutions.
In New Zealand, property owners generally have the right to trim encroaching branches back to their boundary, subject to applicable tree protection rules. This is known as the right of abatement. However, being legally allowed to trim a branch doesn't automatically mean it's safe to do so yourself. Large branches, difficult access and the risk of damaging the tree can make professional pruning the better option.
1. Tree Branches Hanging Over Your Roof
Branches growing over a house can create several problems. Leaves and debris may collect in gutters, branches can rub against roofing materials, and heavy limbs may become a concern during strong winds.
Depending on the tree's structure, professional pruning can remove or reduce branches growing towards the building. The aim is to create appropriate clearance without unnecessarily removing healthy growth.
For large established trees, this often requires careful planning to avoid creating an unbalanced canopy.
2. Neighbour's Trees Blocking Sunlight
One of the most common complaints about overgrown boundary trees is the amount of shade they create. A mature tree can significantly reduce sunlight reaching windows, gardens and outdoor entertaining areas. However, removing the tree isn't always necessary.
Crown thinning selectively removes suitable branches within the canopy, while crown reduction reduces the overall size or spread of parts of the crown.
Depending on the species, location and structure of the tree, these techniques may improve light penetration while retaining much of the tree's natural appearance.
It's important to have realistic expectations. Pruning won't always restore full sunlight, particularly when the tree itself is positioned directly in the sun's path.
3. Overhanging Branches Above Fences and Driveways
Boundary trees can become particularly frustrating when branches extend over fences, driveways or accessways. Low-hanging branches may restrict vehicle access, interfere with gates or make routine property maintenance difficult.
Selective branch removal or canopy lifting may help create more usable space underneath the tree. For larger trees, professional equipment may be needed to remove branches safely without damaging fences, vehicles or nearby structures.
4. Can You Cut Large Overhanging Branches Yourself?
Small branches may appear straightforward to trim, but larger limbs are a different story.
Heavy branches can fall unpredictably, particularly when they are under tension or growing over buildings. Incorrect cuts can also damage the remaining tree, potentially creating problems long after the pruning is completed.
Professional arborists assess branch weight, attachment points, surrounding obstacles and the tree's overall structure before carrying out the work. If branches are near electricity lines, do not attempt to cut them yourself. Contact the electricity network operator for guidance on safe, authorised tree work.
5. Can Crown Reduction Solve the Problem?
Sometimes removing a single branch isn't enough. If a tree has become too large for its location, crown reduction may help manage its overall size and spread. This can be useful when branches are extending towards buildings or neighbouring properties.
However, crown reduction needs to be appropriate for the tree species and condition.
Excessive cutting or topping can damage a tree and encourage weak regrowth, potentially creating further maintenance problems. A professional assessment can determine whether crown reduction, selective pruning or another approach is most suitable.
6. What If the Tree Is Damaged or Dangerous?
Not every overhanging tree is dangerous.
However, certain warning signs deserve attention, including:
Large dead branches above buildings or driveways
Cracks or splits in major limbs
Significant storm damage
Visible decay around branch attachments
Sudden changes in the tree's lean
Hanging or partially broken branches
In some situations, removing damaged branches may be enough to reduce the risk.
In others, more extensive pruning or complete tree removal may need to be considered.
If the tree is on your neighbour's property, removal generally requires the owner's agreement or appropriate legal authority.
7. How Do You Arrange Tree Pruning Without Upsetting Your Neighbour?
If possible, start with a friendly conversation explaining which branches are causing problems and what you're hoping to achieve. You might find your neighbour has been meaning to organise tree maintenance themselves.
Getting professional advice can also make the conversation easier. Rather than arguing about whether a tree should stay or go, you can discuss practical options such as selective pruning, crown reduction or removing specific problem branches.
If the tree is protected, additional council requirements may apply.
