Providing for EN activities and managing the effects of proposed EN activities on the environment

Policy 5
  1. Decision-makers must provide for routine EN activities to occur in all locations and environments, provided adverse effects on the environment are, where practicable, avoided, remedied or mitigated, while acknowledging the existing nature of the assets.
Policy 6
  1. In rural environments, decision-makers should ensure that non-routine EN activities seek to avoid adverse effects on outstanding natural features and landscapes, areas of high natural character, and areas of high recreation value and amenity.
Policy 7
  1. Decision-makers must recognise and provide for the operational need or functional need of the EN to operate in, be located in, or traverse environments, including
    1. the need for EN assets to convey electricity over long distances and in all locations and environments, including:
      1. within and across urban and rural environments;
      2. within the coastal environment, including the coastal marine area; and
      3. across jurisdictional boundaries within and across districts and regions; and
    2. the need for the EN to operate effectively and efficiently as an interconnected system across New Zealand;
    3. recognition that the ETN and EDN are separate networks that have differing functional needs and operational needs;
    4. the requirement for regular maintenance and upgrading of the EN due to its age, the need to improve EN resilience, and the need to increase and improve capacity to meet changing demand and supply;
    5. the need for the EN to connect to electricity generation, and to respond to demand, wherever located; and
    6. the functional need for the EN to locate in areas at risk from natural hazards, where Transpower New Zealand Limited or the EDN provider have considered and managed potential natural hazard risks.
Policy 8
  1. When considering the environmental effects of EN activities and ancillary EN activities, including measures to avoid, remedy or mitigate any adverse effects on the environment, decision-makers must:
    1. have regard to the extent to which any adverse effects have been avoided, remedied or mitigated through the selection of route, site or method of undertaking the work;
    2. recognise that there may be unavoidable adverse effects, regardless of the route, site and method chosen, with adverse effects reduced as far as practicable;
    3. provide for EN activities that have an operational need or functional need to be in particular locations and environments, including in areas where section 6 matters apply, even where there may be unavoidable adverse effects on those environments;
    4. consider the constraints imposed on achieving those measures by any operational need of the EN;
    5. recognise that development, upgrading and improvement of the EN will be necessary to maintain and improve the capacity and delivery of the EN over time;

    7. adopt relevant international standards (that have been adopted for use in New Zealand), national standards, and recognised best practice standards and methodologies to assess and manage adverse effects; and
    8. consider the financial and timing implications of mitigation measures and any consent conditions to ensure these are proportionate to the adverse effects of the EN or particular EN activities.
Policy 9
  1. In urban environments:
    1. decision-makers must recognise that the EN forms an essential part of well-functioning urban environments that must be provided for;
    2. decision-makers must recognise that the effective and efficient development, operation, maintenance and upgrading of the EN may be appropriate use and development when protecting historic heritage;
    3. decision-makers must ensure, wherever practicable, that new EDN lines are placed underground, particularly within new subdivisions, while recognising the financial and technical constraints of undergrounding;
    4. decision-makers must ensure that, where development will result in an increase in demand for electricity, sufficient on-site space is provided for EDN assets to meet demand; and
    5. local authorities must consult with EDN providers to determine an appropriate method or means for identifying when EDN assets are required to meet increasing demand.
Policy 10
  1. Transpower or the EDN provider must consider practicable opportunities and measures to reduce the existing adverse effects of EN assets when considering non-routine EN activities, taking into account the functional need, operational need and the financial implications of any measures to reduce adverse effects.

Managing the effects of third parties on the EN

Policy 11
  1. Decision-makers and local authorities must manage adverse effects of activities undertaken by third parties on the EN, including by:
    1. avoiding direct effects on the EN;
    2. avoiding reverse sensitivity effects on the EN, to the extent reasonably possible; and

Policy 12
  1. To manage adverse effects of activities undertaken by third parties on the EN:
    1. local authorities must identify and map the ETN and other EN assets of national or regional significance within their district, whether or not these are designated;
    2. decision-makers, as relevant, must engage with the operator of the ETN to implement the buffer corridors, provided in any national environmental standards for electricity networks or similar standards, within which it can be expected that sensitive activities, buildings, earthworks, subdivision and other activities that have the potential to compromise the ETN are to be generally avoided;
    3. decision-makers, as relevant, must engage with EDN providers to implement the provisions of any national environmental standards for electricity networks or similar standards that protect the EDN from adverse effects of third parties;
    4. decision-makers must ensure that buildings, structures, earthworks, subdivision and land use activities are designed and located to maintain safe distances from, and allow sufficient space for access to, and maintenance, construction, development and upgrading of EN assets; and
    5. decision-makers must ensure the nature and location of any proposed trees or vegetation to be planted around the EN do not compromise its function and operation.

Long-term spatial and strategic planning for the EN

Policy 13
  1. When undertaking long-term spatial and strategic planning:
    1. local authorities must engage with EN operators to facilitate the medium- to longterm strategic planning for the construction, operation, maintenance and upgrading of the EN;
    2. local authorities should utilise regional and district spatial plans and future development strategies as tools to identify existing and future EN asset needs and to make provision for sufficient space for EN assets to be developed as far as practicable;
    3. local authorities and decision-makers, as relevant, must recognise that the designation process can facilitate long-term planning for construction, operation, maintenance, upgrading and development of the EN; and
    4. local authorities must recognise that not all EN activities and EN assets can be spatially identified in advance.

Electric and magnetic fields

Policy 14
  1. Local authorities must manage electric or magnetic fields associated with the EN based on recommendations from the World Health Organization monograph Environmental Health Criteria (No 238, Extremely low frequency fields) and International Commission on Non-Ionizing Radiation Protection ‘Guidelines for limiting exposure to time-varying electric and magnetic fields (1 Hz to 100 kHz)’ (Health Physics 99(6): 818–836; 2010) (ICNIRP Guidelines) or their revisions, or any other applicable New Zealand standards

Part 3: Timing

3.1 Timing

  1. Decision-makers must give effect to this National Policy Statement on and from the commencement date.

Explanatory note

This note is not part of the National Policy Statement for Electricity Networks but is intended to indicate its general effect.

This National Policy Statement amends the National Policy Statement on Electricity Transmission 2008.

This National Policy Statement recognises the electricity network as a matter of national significance under the Resource Management Act 1991 (the Act). 
New Zealand needs to invest in electricity networks to support growth of the economy, support new housing development, provide for the wellbeing of people and communities, improve resilience and achieve better environmental outcomes, including support for achievement of climate change and renewable energy targets.

This National Policy Statement applies to all decisions made under the Act affecting the development of new electricity networks and the operation, maintenance, renewal and upgrade of existing electricity networks, including all electricity transmission and distribution networks.

This National Policy Statement acts in parallel with the National Policy Statement for Infrastructure 2025 and the National Policy Statement for Renewable Electricity Generation 2011, which have interfaces with, but do not overlap with, this statement.

The National Policy Statement for Indigenous Biodiversity 2023 does not apply to the development, operation, maintenance or upgrade of electricity transmission network assets and activities.

No national policy statement overrides another. Each national policy statement must be applied to the relevant decision-making process.

In relation to managing the effects of EN activities, this national policy statement must be read alongside other national direction and local authority planning documents that govern RMA section 6 matters. The protection of section 6 RMA matters is achieved through Policy 6 ‘seek to avoid’ and Policy 7(1) ‘functional and operational need’ which set a high bar for EN activities to be located in section 6 environments. However, this NPS acknowledges that for linear network infrastructure required to connect to demand and supply, avoidance of all section 6 values along the length of a route is not always possible.

This National Policy Statement is to be applied by all persons exercising powers and functions under the Act. The objective and policies are intended to guide decision-makers in making decisions on the determination of resource consent applications, in considering a requirement for a designation or a heritage order, in considering an application for a water conservation order and when exercising other relevant powers as required by the Act. The objective and policies will also provide guidance for local authorities in relation to plan making.

In applying this National Policy Statement, local authorities should be aware of their obligations with regard to other legislation, including Te Ture Whenua Māori Act 1993, the Local Government Act 2002, Treaty settlement legislation, iwi participation legislation and the Treaty of Waitangi. Local authorities should also be aware of their obligations in any Mana Whakahono ā Rohe agreement they may have with relevant hapū and iwi.

In August 2025, the Government passed an amendment to the Act that introduced a requirement to stop most plan making under the Act, unless it was subject to an exemption. This ‘plan stop’ amendment suspends the requirement to review plans and policy statements and prevents notification of new plan or policy statement changes or variations until the end of 2027, when the new resource management system will be in effect.

Due to the plan stop amendment, plans and policy statements will not be updated to give effect to this amendment (unless a relevant exemption applies).

For the avoidance of doubt, plan and policy statement content that implements the original National Policy Statement on Electricity Transmission does not require amendment.
