Explanatory note
This note is not part of the regulations but is intended to indicate their general effect.
These regulations, which come into force on 17 October 2024, amend the Electricity (Hazards from Trees) Regulations 2003 (the principal regulations). The principal regulations set out rules and requirements to deal with hazards caused by trees to electricity lines to protect the security of the supply of electricity and the safety of the public. In particular, the principal regulations prescribe a growth limit zone around electrical conductors. Works owners who become aware of a tree encroaching into the growth limit zone must give a cut or trim notice to the tree owner, requiring the tree to be cut or trimmed.
The amendments in these regulations extend the growth limit zone for high voltage, uninsulated conductors and conductors with spans of more than 150 metres to be “clear to the sky”
. This means any part of a tree encroaching above those conductors would need to be cut back. However, the clear to the sky requirement will not apply if a tree is protected under a district plan. For protected trees, there is no change to the growth limit zone.
There is no change to the growth limit zone for insulated or low voltage conductors with spans of 150 metres or less.
The principal regulations also prescribe a notice zone around the growth limit zone, and permit a works owner who becomes aware of a tree encroaching into the notice zone to give a hazard warning notice to the tree owner. The amendments extend the notice zone by an additional metre for all types of conductors.
The amendments provide a grace period in relation to the new growth limit zone. Until 16 October 2026, it will be optional for works owners to give cut and trim notices in relation to trees that encroach into the new areas of the growth limit zone. From 17 October 2026, it will be compulsory for works owners to give cut and trim notices for any encroaching trees in the new growth limit zone.
The amendments prescribe a new zone, the cut-back zone. This zone extends 1 metre from the growth limit zone. Under a cut or trim notice, trees must be cut or trimmed so that they do not encroach into the cut-back zone. This replaces the previous requirement for trees to be cut or trimmed so that they do not encroach into the notice zone. As the amendments extend the notice zone by 1 metre, the new cut-back zone effectively preserves the status quo.
The amendments require all works owners to provide consumers with updated information on the different zones by 31 January 2025.
The amendments will not affect existing dispensations, or applications for dispensations not yet determined.
