As New Zealand enjoys autumn, many of us are preparing our homes and gardens for the colder months ahead. One important task that often goes overlooked is the maintenance of trees, particularly those near powerlines.

According to Powerco, property owners are legally required to keep trees a minimum safe distance away from overhead lines under the Electricity (Hazards from Trees) Regulations. “If your tree grows too close, you must get it trimmed by an approved contractor.”

As autumn winds pick up and winter storms approach, branches that grow too close to or touch powerlines can become a hazard. High winds can cause these branches to snap, which may lead to power outages, fires, or even electrical shock risks.

Unpredictable weather

In the Bay of Plenty, where winter months can bring unpredictable weather conditions, it’s important to take proactive steps to reduce these risks.

Properly trimming trees near powerlines not only helps ensure a safer environment but also improves the reliability of your local power supply.

Autumn is the ideal time to address tree maintenance before the full force of winter sets in. Trees are entering their dormant phase, which means trimming them now has less impact on their overall health. The cooler weather also makes the job more manageable, with less risk of overheating or working in heavy rain.

Additionally, pruning trees before winter ensures any weak or damaged branches are removed, preventing them from being a threat during storms. This will also help to improve airflow around the tree, reducing the likelihood of branches becoming entangled in power lines when the winds pick up.

Where to start

Firstly, walk around your property and take note of any trees that are growing near powerlines. If the tree is too close to the power lines for you to trim safely, you must contact your local power provider for their advice first. Never attempt to trim or remove branches that are in direct contact with power lines yourself.

Trees should be pruned at least once a year to maintain healthy growth and prevent dangerous situations. Removing excess growth now can help avoid bigger problems in future. If you are unsure about how to safely trim trees, or if the task requires working at heights, it’s best to hire a professional arborist.

Trimming trees before winter is also a smart investment in the safety and protection of your home – most likely your biggest asset.
