Trees Near Power Lines

Trees and shrubs are an important part of our environment and we encourage plantings as long as the trees or shrubs planted near power lines cannot grow to a height that would put them in contact with the power lines.

Be aware that if your trees damage a power line you could be held responsible for the cost of repairs including any damage to a third party.

If there is a power line within the fall distance of your tree, consider if its advisable to remove the offending tree or, at least talk to your advisor about taking out public liability insurance.

  • Trees on private land are the responsibility of land owners.

  • Tree cutting safety

If there are four metres or more clearance between trees and a power line there is no need to contact Network Waitaki. Trees can be trimmed by yourself or any contractor.

If trees are less than four meters from a power line then only a network approved contractor can trim them. Please contact Network Waitaki and allow some time for communication between us and our approved contractor.

If trees require a power outage to safely trim them, then additional charges may apply. Allow sufficient time to arrange the outage between Network Waitaki and the contractor.

  • Council Trees

Waitaki District Council has its own contractors to undertake tree work. For any enquiries regarding council trees and power lines contact Waitaki District Council on 0800 108 081.

  • Tree Felling or Forestry Work 

Any forestry work which requires tree felling within 2 tree lengths of a power line must have written approval by Network Waitaki. This is a requirement of Worksafe New Zealand.

  • Approved Tree Workers

Only Network Waitaki approved arborists and operators of mobile mechanical trimming of trees, hedges and shelter belts may carry out work within 4 metres of a power line. There may be additional charges if power needs to be switched off to trim your trees.
