In New Zealand, if a tree from a neighbouring property overhangs your land, you have the right to trim branches or roots that cross into your property, but only up to the property boundary. 

However, you cannot damage or remove the tree itself without the owner’s permission.

Both you and your neighbours are responsible for ensuring that trees and large plants do not cause problems for others.

 If an overhanging tree is causing issues, it’s best to discuss the matter with your neighbour first. 

If the tree poses a danger or is blocking access, your local council may be able to provide guidance.

Tree trimming is commonly referred to as pruning when it involves removing unnecessary or unhealthy branches to improve tree health. Trimming, on the other hand, is typically done to shape a tree and encourage balanced growth.

Tree Pruning – Focuses on removing dead, diseased, or weak branches to promote overall tree health and structure.

Tree Trimming – Helps control overgrowth, improve appearance, and allow better light penetration.

Both processes use tools like shears, saws, and trimmers, depending on the size and type of branches being cut.

In New Zealand, professional arborists typically charge between $75 – $100 per person per hour (excluding GST). Prices can vary depending on factors such as:

The complexity and size of the job

Accessibility and location of the tree

Specialised equipment required

Whether additional services like stump grinding or waste removal are included.

For larger projects or emergency tree work, some companies may offer fixed quotes instead of hourly rates. 

It's always best to get a detailed quote upfront to understand the full cost of the service.

The best tree trimming technique depends on the type of tree and the goal of the trim. However, proper pruning methods help maintain tree health, structure, and appearance. Key techniques include:

Cut Back to a Bud or Branch – Always trim back to a healthy bud or branch rather than leaving stubs. This encourages healthy regrowth.

Select Outward-Facing Buds – Cutting to a bud that faces outward helps prevent branches from growing inward and crisscrossing.

Avoid Over-Pruning – Removing too much foliage at once can stress the tree and affect its ability to produce energy.

Use the Three-Cut Method for Large Branches – To prevent tearing, make an initial notch cut on the underside of the branch, then a second cut further out to remove the branch. Finish with a clean cut at the branch collar.

Trim at the Right Time of Year – Most trees respond best to trimming in late winter or early spring before new growth begins.

Using these techniques ensures that trees stay strong, healthy, and well-shaped.

The best time to trim trees in New Zealand is late winter to early spring (July to September).

Deciduous trees - Trim before new growth starts to see the structure clearly.

Less stress - Pruning in dormancy helps trees recover faster.

Healthier growth - Reduces risk of disease and pest infestations.

Cut back to a bud or branch for healthy growth.

• Choose buds facing outward to direct growth away from the tree’s interior.
• Avoid crisscrossing branches by trimming strategically.
• Encourage strong structure by maintaining open space within the tree.
