Unison urges its communities to keep trees clear of powerlines ahead of El Niño

Unison Networks (Unison) is encouraging residents across Hawke’s Bay, Taupō and Rotorua to ensure trees on their property are clear of power lines ahead of an expected hot, dry summer.

A very strong El Niño is expected to bring more frequent, gusty winds across New Zealand, with drier, warmer conditions particularly likely in eastern regions over spring and summer. These conditions can increase fire risk, while trees and branches near power lines can bring down lines during high winds, causing power outages and creating serious safety risks.

Unison is asking residents, farmers and lifestyle block owners to check the trees on their properties before summer conditions intensify. Property owners are responsible for looking after their own trees, but if a tree is growing close to power lines, don’t trim it yourself. Electricity can travel through trees and branches that are in contact with power lines, creating a risk of serious injury or electrocution. Instead, report it online at unison.co.nz/reportaproblemtree and Unison can assess the situation and advise on the safest next step, including any costs involved. In Taupō and Rotorua, property owners can also arrange the work directly through Unison’s approved vegetation contractor, Treescape, on 0800 873 396.

Gagan Chadha, General Manager Networks & Operations, says preparation is one of the most effective ways to reduce risk.

 “Taking a few minutes now to look around your property and identify trees growing near power lines can make a real difference as conditions become hotter and drier over summer.”

“Keeping trees clear of power lines helps reduce fire risk, prevent avoidable outages and protect homes, farms and communities. It also supports a safe and reliable electricity supply when severe weather hits.”

 Chadha says people should not attempt to deal with trees near power lines themselves.

 “What we don’t want people doing is grabbing a chainsaw and trying to solve the problem themselves. If you, the tree, or any tools or equipment could come within four metres of a power line, don’t attempt the work yourself. Report it to Unison through our website and include a photo so our team can assess the risk and make sure any required work is done safely.”

The reminder is particularly relevant for rural property owners, farmers and lifestyle block owners, who often have larger numbers of trees, shelterbelts and boundary plantings on their properties.

People planning new planting near power lines should avoid planting directly beneath or too close to lines where possible. If planting nearby cannot be avoided, choose species that will remain a safe distance from lines when fully grown. Guidance is available at unison.co.nz/plantingguide.

Reducing fire risk and preventing vegetation-related outages is a shared responsibility. Small actions taken now can help communities prepare for the months ahead.
