The purpose of the High-Voltage Transmission Plan Area is to identify the high-voltage transmission network within the City and to provide for the sustainable, secure and efficient use and development of that network. The network, and its associated buffer areas are identified and provided for through objectives, policies and rules as the National Policy Statement on Electricity Transmission contains an explicit requirement to manage third-party risks within the Plan. Such-third party risks include:
- Activities in close proximity to transmission electric lines and support structures that can generate adverse effects on the lines and support structures;
- Transmission electric lines and support structures adversely affecting new land uses.
The Plan Area also recognises that the location and scale of regionally significant infrastructure should be taken into account at an early stage of subdivision, land use and the development process; and that because the national grid traverses sites it can be sensitive to effects that do not otherwise extend beyond the site boundary.
The network, and associated buffer areas, are identified and provided for through objectives, policies and rules. The overall intent of the High-Voltage Transmission Plan Area is to manage the subdivision, use and development process within a defined area of the high-voltage transmission network. The Rules that apply within the Plan Area specifically recognise the nature of Tauranga City and of Transpower’s assets within the City. This includes:
- That the City is predominantly urban in nature, with considerable existing under-build and limited opportunity for further infill subdivision or development in and around some of the existing lines, and/or for the upgrading of those lines;
- Most of Transpower’s assets within the City are located within the road reserve rather than on private land, so access to the assets is not, and is unlikely in the future to be, restricted by development;
- Most of the assets within the City have lower support structures and span lengths between support structures that are at the lower end of the continuum and which are less variable than in other districts;
- Some of the lines within Tauranga City are termination lines, rather than critical supply lines; and
- Greater recognition and protection is required for key strategic assets (Kaitemako Corridor).
Where the line is a critical corridor of supply into Tauranga, a more commonly adopted or standardised approach has been taken. This is a more conservative approach than has been adopted on the other lines.
