Trees Near Power Lines: What Property Owners Need to Know
- Jul 14
- 2 min read
Trees are an important part of many properties, providing shade, privacy, and character. However, when trees grow too close to overhead power lines, they can become a serious safety hazard.
Whether it's a mature tree on your property or branches extending towards roadside power lines, knowing when to act can help prevent damage, reduce risks, and keep your property safe.

Why Are Trees Near Power Lines Dangerous?
As trees grow, branches can begin to interfere with overhead power lines.
This can lead to:
Power outages
Fire risks during dry conditions
Falling branches during high winds
Damage to electrical infrastructure
Serious safety hazards for people nearby
Strong Canterbury winds can cause branches to move unexpectedly, increasing the chance of contact with nearby power lines.
Can You Trim Trees Near Power Lines Yourself?
In most situations, no.
Working near electricity lines is extremely dangerous and should never be attempted without the appropriate training, equipment, and authority.
If branches are growing close to overhead power lines, avoid attempting to prune or remove them yourself. Instead, contact the appropriate electricity network company or seek advice from a qualified arborist who can help determine the safest course of action.
Your safety should always come first.
Warning Signs Your Tree Needs Attention
It's a good idea to regularly inspect trees on your property.
Look for:
Branches growing towards overhead lines
Trees touching or very close to power lines
Dead or damaged branches
Leaning trees
Broken limbs after storms
Fast-growing trees that haven't been maintained for several years
Addressing these issues early is often much easier than dealing with emergency damage later.
Canterbury Weather Can Increase the Risk
Canterbury experiences strong winds throughout the year, particularly during seasonal weather events.
Even healthy trees can lose branches during high winds, and overgrown trees near power lines become a much greater risk.
Regular tree maintenance helps reduce the chance of branches breaking or interfering with electrical infrastructure.
The Importance of Regular Tree Maintenance
Professional tree maintenance isn't just about appearance.
Routine pruning can:
Reduce overhanging branches
Improve tree structure
Remove deadwood
Reduce storm damage risk
Encourage healthy growth
Help prevent future safety issues
Keeping trees properly maintained also helps protect neighbouring properties and public spaces.
When Should You Contact an Arborist?
Consider arranging a professional assessment if:
Branches are growing towards power lines.
Your tree has become significantly larger over the past few years.
Storm damage has affected the canopy.
You're unsure whether the tree presents a risk.
You're planning other tree maintenance and want expert advice.
An experienced arborist can assess the tree's health, growth, and condition while helping you understand the safest options available.
