We are reviewing how the system is managed through a regional plan review and want to know what you think. This document gives you some background on the Rotorua Geothermal System, how we look after it now, and possible future management options. There are some questions for you to think about. You may also have some other comments or questions for us. What are our knowledge gaps? What are our ROTORUA What do priorities? SYSTEM you value?

Regional plans must give effect to the RPS. This means that they must follow the direction set in the RPS – basically, they It will contain all of the broad principles for managing the system. After that, we will develop must do what the RPS says, following the a draft regional plan for public comment, before publicly notifying a formal proposed regional steps it sets out. We do have some flexibility plan change for formal submissions and hearings under the RMA. in how we do this, so we can add detail and look at different options to achieve what The RPS has already identified the management purpose for the system that we need to work the RPS requires. And we can identify new towards (our end goal). We now need to check that the issues and objectives in the regional issues that are not covered in the RPS. plan are still relevant, and the policies and rules are still the best way to achieve the objectives, as shown in the diagram below. Regional plans set the rules for use of the geothermal resource. They include It is a good idea to keep the parts of the plan that are working. But we do need your ideas objectives, policies, rules on activities, about whether we need to change or improve anything. allocation of resource use within limits, and things that must be considered in resource consent applications.

Council is reviewing the geothermal parts of both of these regional plans, starting with the Rotorua Geothermal Regional Plan. 7 PROCESS AND TIMEFRAMES We’re still in the early stages of this process, and we don’t expect to notify a plan change until late 2020.
