Keep your trees away from power lines
Trees can be a major hazard
Trees are one of the leading causes of power outages, both at individual properties and across the wider network. When vegetation grows too close to power lines, it can cause serious safety risks and disrupt supply.
- Vegetation that comes into contact with power lines can cause power surges, power outages and fire
- If a tree is in contact with power lines, stay clear and call us
- In high winds and storms, falling trees and branches can break lines and cause power cuts
- Trees or vegetation too close to lines increases the fire risk, especially in hot, dry, and windy weather

Who is responsible for keeping trees clear of power lines?
If you own the land where a tree is growing, it’s generally your responsibility to keep it clear of power lines.
Northpower undertakes regular tree surveys to help monitor the 5,500km of our network. If we identify a potential issue, we’ll notify you.
Need help?
Our team of approved contractors can assist with safely managing trees near power lines. Never attempt to trim vegetation within 4 metres of power lines — only qualified professionals should work this close to live electricity.
