If you have trees on your property you need to know the regulations about trees and power lines

Tree Regulations

The current tree regulations have been in effect since 1 July 2005. The regulations provide for the control of trees adjacent to electricity lines. Network Tasman, along with all line companies in New Zealand, is required by law to administer the tree regulations. 

The purpose of the regulations is to protect the safety of the public and the security of the supply of electricity by:

  • prescribing minimum distances between power lines and trees
  • assigning responsibility for cutting or trimming trees close to power lines
  • establishing rules and penalties if the regulations are not complied with
  • providing an arbitration system to resolve disputes between electricity lines companies and tree owners over the operation of the regulations.

The tree regulations require Network Tasman to issue a range of notices to support these objectives. Trees outside these regulations will come under Network Tasman’s Vegetation Policy.

Qualified Contractors

The only tree contractors in the Network Tasman area that are currently qualified to work in close proximity to live power lines are listed below. Any trees notified to you in a CT Notice must only be cut by one of these tree contractors.
