Table A1: Summary of NES activities

Activity		C	RD	D	NC
All transmission activities that meet specified terms and conditions, set out below according to the type of activity they apply to.
Addition or replacement of overhead conductors (up to duplex, up to 50 mm or existing diameter).
Addition or replacement of overhead circuits, conductors or earth wires, and cables in excess of the number or size specified for permitted activities.
Addition or replacement of overhead earth wires and aerial communications cables, including earth wires containing optic fibres (up to 3 wires or existing number, up to 25 mm or existing diameter).
Addition or replacement of overhead circuits, conductors or earth wires, and cables in excess of the number or size specified for permitted activities.
Adding circuits (where support structure was designed and built to carry an extra circuit).
Adding circuits to other lines.
Increasing the voltage or current rating of a line and adding conductors and circuits where ICNIRP guidelines for EMF are met.
Activity resulting in generation of EMF (if it fails the terms and conditions for a permitted activity).
Replacing, moving and upgrading of support structures and foundations (max. height increase 15%, max. footprint increase 25%, pole not replaced with a tower, no relocation outside relocation envelopes).
Replacing, moving and upgrading support structures and foundations, exceeding permitted thresholds but meeting controlled activity thresholds.
Replacement or alteration of a pole or tower that does not meet the thresholds as a permitted or controlled activity.
Removal of transmission support structures, conductors and associated foundations (site clean-up and rehabilitation).
Removal of transmission support structures, conductors and associated foundations failing permitted terms and conditions.
Application of surface coatings (no noxious discharge).
Application of surface coatings failing the terms and conditions for a permitted activity.
Wet, dry and non-abrasive blasting (not within 50 m of water body or public road or 100 m within occupied building; no chemicals; collect waste; no discharge).
Wet, dry and non-abrasive blasting not complying with permitted but not undertaken over water in coastal marine area, not within 100 m of an occupied building or over a road and application of surface coatings not complying with permitted activity.
Wet, dry and non-abrasive blasting over coastal marine area water and within 100 m of an occupied building.
Temporary structures and temporary line deviation.
Temporary structures exceeding time constraints.
Signs attached to transmission infrastructure (size, purpose).
Signs above the size limit.
Trimming or removal of trees or vegetation for transmission line maintenance and ongoing operation (not protected individually or as a part of scheduled areas; not part of river and erosion control management schemes; not within DoC land).
Trimming or removal of generally protected trees/vegetation (not individually scheduled trees).
Trimming or removal of individually protected trees for the purpose of reducing risk to transmission lines which do not comply with the terms and conditions for a permitted activity.
Earthworks, including tracking, associated with transmission activities (volume and area limit; no more than 50 m3 per tower or pole or 100 m3 per track in scheduled areas; soil erosion protection; remediation; no contribution to instability or erosion; prevent debris from entering water body or coastal marine area; no earthworks in coastal marine area or beds of lakes and rivers; no works in archaeological areas, wāhi tapu or other scheduled areas).
Earthworks that do not meet permitted activity conditions, but excluding earthworks in scheduled landscape, or ecological or heritage areas of cultural significance.
New access tracks to transmission lines not in scheduled landscape, or ecological area or areas of cultural significance.
Earthworks associated with works or involving access to a line in scheduled landscape, or ecological or heritage areas of cultural significance.
New access tracks resulting in loss or removal of trees or vegetation protected in a plan or land that is part of a protected natural feature, archaeological site or site of significance to Māori.
Construction noise and vibration associated with transmission activities (including implosive jointing, noise complies with NZS 6803:1999, vibration complies with DIN 4150-3:1999).
Noise that fails to meet permitted activity standards, terms and conditions.
Installation of antenna dishes on transmission line support structures.
Telecommunication facilities on existing transmission line support structures which do not meet the terms and conditions for permitted activity.
Transmission activities over surface water or over the coastal marine area (no activities at ground level).
Discharges of water and contaminants from transmission activities.
Discharges to water and the coastal marine area that fail to meet permitted activity standards, terms and conditions.
Undergrounding of existing transmission lines, including termination towers, that meet the permitted activity standards for increasing the voltage and current rating.
Any transmission activity that does not meet the terms and conditions for permitted activity and is not listed as permitted, controlled, restricted discretionary or discretionary.
