Your First Cut or Trim is free

The First Cut or Trim Notice, issued by Horizon Networks to the tree owner, differs from all subsequent notices because Horizon Networks meets the cost (provided no prior agreement is in place and provided the tree owner grants access to the site). Subsequent tree clearance work will be the tree owner’s responsibility. 

Subsequent tree cuts and trims: The responsibility is yours

Under the tree regulations the responsibility for trimming the trees is yours, if one or more of the following criteria apply:

  • According to Horizon Networks’ records the trees have been subject to a previous cut or trim at our cost.
  • The trees form a shelterbelt.
  • The trees have been the subject of a previous agreement.
  • Purposely planted production trees e.g., forest harvesting.
  • In these circumstances a Cut or Trim Notice will be issued:
  • The tree owner is responsible and liable for the direct costs of this work and to prevent or remedy any damage caused to Horizon Networks’ electricity network.
  • The work must be completed within the time frame stated on the cut or trim notice and you must notify Horizon Networks at least three working days before work is to commence.

Please read the back page of the notice as there are several important points about the tree regulations that you need to know, including the following:

Failure to Comply with the Cut or Trim Notice

Refer Regulation 14, Electricity (Hazard from Trees) Regulations.

Failure to cut or trim your trees in the specified time frame may result in Horizon Networks completing the necessary work at your expense, to remove any immediate hazard to persons, property or electricity conductors.

Horizon Networks will recover any amount payable from the tree owner that may include:

  • The costs of any cutting or trimming work.
  • The costs of any isolation, earthing operation and safety operation that is necessary to complete the work.
  • The costs of the removal of any debris.
  • The costs of remedying any damage to works, where that damage arises (whether directly or indirectly) out of a tree owner’s failure to comply with the requirements of these regulations.

You Need an Approved Contractor

Cutting and trimming trees in the vicinity of power lines is dangerous. Touching the live power line or a tree close to the line, can result in serious injury or even death by electrocution.

Under the electricity regulations, no person is permitted within four metres of a power line without approval. In the Eastern Bay of Plenty region, this approval can only be granted by Horizon Networks.

An approved contractor must be used if any part of the tree is within four metres of the power lines. Remember… no DIY tree trimming near power lies. Use an approved contractor.


Action to be Taken Codes

The above table explains the action codes that may appear on the notice.

Growth Limit Zone


Overhead Line Notice Zone Growth Limit Zone
33kV - High Voltage 3.5 metres 2.5 metres
11kV - High Voltage 2.6 metres 1.6 metres
400V/230V - High Voltage 1.5 metres ½ metre

1. The above distances are from power lines.
2. Distances must be maintained under all conditions, e.g. high wind.
3. Low voltage is the power line between the house/building and Horizon Networks’ transformer.

Fall Zone

It is important to realise that larger trees located outside the minimum safe distance from power lines can still fall through the lines. Any work that occurs within four metres of power lines requires Horizon Networks consent.

Think before you plant your trees. Serious consideration should be given to the species and placement of trees on your property to ensure they don’t interfere with the power lines now and in the future.

Remember – that lovely little shrub you planted may become a five metre monster in a few years!
