- Extremely low frequency (ELF)
- An electromagnetic field having a frequency between 1 Hz to 300 Hz. Transmission lines produce fields with a frequency of 50 Hz and are therefore regarded as having ELF fields. (This is much lower than the frequencies of signals typically used in communications which are not ELF).
- Grid entry points
- Points in the transmission network at which electricity enters the network. These are typically at, or near, places of generation.
- Grid exit points
- Points on the network at which electricity exits the network. Each Grid Exit Point is a substation where electricity transported through the national grid is converted to lower voltage for distribution by local distribution companies.
- Historic heritage
- Has the meaning described in section 2 of the Resource Management Act 1991
- HVDC Link
- The converter stations at Benmore in the South Island and Haywards in the North Island and the high voltage transmission lines and undersea cables linking them (and including their associated equipment).
- kV
- The unit of electrical potential equal to 1000 volts.
- Nationally significant

- The Resource Management Act 1991 and its amendments.
- Section 32
- The section of the RMA that requires any person developing policy or regulatory instrument under the RMA to carry out an evaluation of alternatives, costs and benefits of what is proposed.
- Support Structure
- Any structure designed to keep conductors at a safe distance above ground and includes pylons and poles.
- Transmission network
- The system of transmission lines, substations and other works, including the HVDC link, used to connect grid injection points and grid exit points to convey electricity throughout the North and South Island of New Zealand.
- Transmission project
- A physical work involving the extension, maintenance, repair or upgrading of any part of the current or future transmission network.
- Transpower
- The state owned enterprise known as Transpower New Zealand Ltd.
