Management of geothermal systems

How are the systems managed?

Bay of Plenty Regional Council is responsible for managing the sustainable use of the geothermal resource in the region, including:

  • the development of policy to guide use of the resource
  • allocation through resource consents
  • monitoring and research to measure the state of the resource.

The geothermal systems in the region have been classified into management groups which reflect their unique values and current uses. The classification process is set out in the Regional Policy Statement (please see link below).

The purpose of the classification is to manage the region’s geothermal resource sustainably by establishing different management purposes for different systems e.g. the extractive use of the resource is confined to some geothermal systems, while other systems are protected for their intrinsic values.

The six management groups are:

Group 1 – Protected Systems e.g. Waimangu-Rotomahana-Tarawera

Group 2 – Rotorua System

Group 3 – Conditional development systems e.g. Rotomā-Tikorangi

Group 4 – Development systems e.g. Kawerau

Group 5 – Low temperature systems e.g. Tauranga

Group 6 – Research systems

The challenge to protect intrinsic and traditional cultural values while providing for the use of the energy resource. Council does this by taking a region-wide approach, providing for different values at a regional level rather than trying to provide for all values within each system.

Planning provisions

The Regional Policy Statement sets the overall direction for geothermal management through objectives and policies. It classifies geothermal systems and requires the development of system mangement plans for some systems. The relationship of Māori and their culture and traditions related to geothermal resources must also be recognised and provided for.

Regional plans give effect to the Regional Policy Statement and set the rules for use of the resource. Geothermal provisions are currently in the Regional Natural Resources Plan and the Rotorua Geothermal Regional Plan (please see links below). They include rules on activities, allocation of limits, and things that must be considered in resource consent applications. For example, resource consent is required to construct a new geothermal well or to take geothermal fluid or energy from any geothermal system. Decisions must consider the effects of that use on the system and other users, and on geothermal surface features.


Land Use

Because geothermal surface features are so fragile, land use around surface features is carefully managed by the Bay of Plenty Regional Council and also by the relevant district or city councils.

Along with potential damage to surface features, any work near surface features will also need to consider issues like health (some natural gases can be harmful at high levels) and site stability. Geothermal sites are dynamic and can change very quickly.

If you wish to undertake any activity, such as building works, vegetation clearance or earthworks near a surface feature, you may require resource consent from the Bay of Plenty Regional Council or your district or city council under their district plan.

Statutory Acknowledgements

Many iwi and hapū hold a statutory acknowledgement over geothermal resources in parts of the region. A statutory acknowledgement is a formal acknowledgement by the Crown that recognises the particular cultural, spiritual, historical and traditional association of iwi with a site of significance or resource identified as a statutory area. The statutory areas include Crown land, geographic features, lakes, rivers, wetlands and coastal marine areas. Check out the Statutory Acknowledgements link below for more information.
