How the National Environmental Standards deal with electricity transmission activities (12 of 12)

These pages set out aspects of the NES that Transpower and councils need to consider for transmission activities.

  1. Summary of the NES
  2. Operation of existing transmission line and use of access tracks
  3. Overhead conductors and adding overhead circuits
  4. Earthwires and telecommunications cables
  5. Work on underground conductors / Taking existing overhead transmission lines underground
  6. Increasing voltage or current rating / Electric and magnetic fields
  7. Transmission line support structures — alteration, relocation, and replacement / Temporary / Removal
  8. Telecommunications and signs / Devices / Signs
  9. Discharges
  10. Trimming, felling, and removing trees and vegetation
  11. Earthworks
  12. Noise and vibration from construction activity

Noise and vibration from construction activity

Noise can be generated from activities such as the use of machinery, piling, and implosive jointing of conductors.

Explanation: noise and vibration permitted

Noise and vibration from construction activities (including demolition and removal of structures) is permitted by regulation 37. However this is subject to meeting both the New Zealand Standard NZS6803:1999 Acoustics-Construction Noise, and the limits in Table 1 of the German Standard DIN4150-3:1999 Structural Vibration – Effects of Vibration on Structures. These standards can be inspected at the Wellington office of the Ministry for the Environment or purchased from Standards New Zealand.

Explanation: noise and vibration controlled

If the permitted activity conditions in regulations 37 (2) and/or (3) are not met, the activity is controlled under regulation 38. The territorial authority (or the regional council, if the noise is in the coastal marine area) can take account of the effects of the noise and set conditions to limit the effects, in terms of:

  • timing of the works
  • effects on sensitive land uses
  • giving of notice of the works to parties who may be affected.

Other transmission activities

Explanation: other transmission activities

Any transmission activity that is included within the scope of the NES Which activities are covered by the NES but not specifically provided for will be full discretionary.

Refer to regulation 39.
