Section 12 - Karāpiro and Arapuni Hydro Power Zone 12.1 Introduction 12.1.1 The Waikato River sustains the Waikato Hydro Scheme. The Hydro Scheme comprises nine power stations and eight dams along the River, two of which are located within the Waipā District, being Karāpiro and part of Arapuni. The electricity generated from both of these power stations contributes to New Zealand’s renewable electricity generation. The hydro electric power generation infrastructure at Karāpiro comprises a dam, diversion tunnels, headrace, intakes, penstocks, tailrace, turbines, powerhouse, switchyards, transformers, transmission lines and associated buildings and structures, dam abutments, tracks and roads. The spillway structure at Arapuni is the only part of the Arapuni infrastructure located in the Waipā District. Both sites are provided for as part of the Karāpiro and Arapuni Hydro Power Zone. 12.1.2 Within the Karāpiro and Arapuni Hydro Power Zone, provision has been made for a “Hydro Electric Power Generation Infrastructure Area” or “HEPA”. The HEPA comprises the core area of operations where hydro electric power generation activities occur. Within the HEPA the rule framework permits the existing and continued operations and activities associated with the Hydro Power Scheme, with some additional controls applying outside of the HEPA. The HEPA at Karāpiro and Arapuni is mapped in Section 12.6 of this chapter. 12.1.3 The National Policy Statement for Renewable Electricity Generation 2011 promotes renewable electricity generation. The development, operation, maintenance and upgrading of new and existing renewable electricity generation activities, and the associated benefits of renewable electricity generation, are matters of national significance. The Karāpiro and Arapuni Hydro Power Zone is intended to give effect to this National Policy Statement by providing for the development, operation, maintenance and upgrading of existing hydro-electricity generation activities in the District. 12.1.4 This Plan is also required to give effect to Te Ture Whaimana o Te Awa o Waikato – The Vision and Strategy for the Waikato River that arises from the Waikato-Tainui Raupatu Claims (Waikato River) Settlement Act 2010 and Ngāti Tūwharetoa, Raukawa and Te Arawa River Iwi Waikato River Act 2010 (Upper River Act). The Vision and Strategy for the Waikato River is the primary direction-setting document for the Waikato River and its catchments. Section 12(1)(a) of the Waikato-Tainui Raupatu Claims (Waikato River) Settlement Act 2010 and Section 11(1) of the Ngāti Tūwharetoa, Raukawa and Te Arawa River Iwi Waikato River Act 2010 (Upper River Act) states that the Waikato River Vision and Strategy prevails over any inconsistent provision in a National Policy Statement including the National Policy Statement for Renewable Electricity Generation 2011. 12.1.5 This Plan therefore seeks to give effect to the National Policy Statement for Renewable Electricity Generation 2011 and the Waikato River Vision and Strategy through Plan provisions relating to the generation of renewable electricity generation which utilises that part of the Waikato River’s hydro scheme located within the Waipā District. 12.1.6 This Plan also seeks to manage reverse sensitivity effects on land adjoining this zone.

As such, the continued operation of the hydro electricity generation infrastructure needs to be provided for, and the practical constraints associated with the operation, maintenance and upgrading acknowledged. 12.2.2 The development of activities sensitive to the effects of the Waikato Hydro Scheme can impact on the efficiency with which the scheme can be operated, maintained and upgraded. Conversely, the extent to which the operation or development of the scheme may create significant additional adverse effects within and beyond the boundary of the zone, will need to be carefully managed. 12.2.3 Activities and development in the Karāpiro and Arapuni Hydro Power Zone need to give effect to Te Ture Whaimana o Te Awa o Waikato (the Vision and Strategy for the Waikato River). 12.2.4 The Waikato River is of paramount importance to tāngata whenua, has high amenity, natural and cultural landscape values, in addition to being used for the generation of hydro electricity. The need to provide for the efficient operation of the Waikato Hydro Scheme needs to be balanced against the requirement to protect the natural character, the maintenance of cultural values and ecosystems of the Waikato River. 12.3 Objectives and Policies Please also refer to the objectives and policies of Parts C, Part E, and Part F as relevant. Objective - Recognising and providing for existing and new hydro electric power generation infrastructure and activities 12.3.1 To recognise and provide for the development, operation, maintenance and upgrading of existing and new hydro-electric power generation infrastructure and activities in a manner that avoids, remedies or mitigates any significant adverse effects on the environment and the health and well-being of the Waikato River. Policy - Enabling hydro electric generation infrastructure and activities 12.3.1.1 To recognise the national significance of the hydro electric power generation infrastructure and activities. Policy - Avoid, remedy or mitigate significant additional adverse effects on the environment from hydro electric power generation infrastructure and activities 12.3.1.2 To avoid, remedy or mitigate any significant additional adverse effects on the environment that result from the operation, maintenance and upgrading of the Karāpiro and Arapuni hydro electric power generation infrastructure and activities. Policy - Works required to protect the Waikato Hydro Scheme 12.3.1.3 To allow for works and activities to protect the operation and use of the Waikato Hydro Scheme, from natural hazards and land instability risks where they threaten the access, operation or safety of the hydro electric power generation infrastructure and activities. Waipa District Plan Section 12 - Karāpiro and Arapuni Hydro Power Zone Page 2 of 15 Page Version - 1 November 2016 Policy - Cross boundary management 12.3.1.4 To recognise that the Waikato Hydro Scheme, including any associated electricity generation and transmission infrastructure, crosses local authority boundaries; and that a consistent approach to District Plan provisions and administration is desirable to ensure their efficient and effective functioning. Objective - Reverse sensitivity effects 12.3.2 To ensure that development and subdivision avoids reverse sensitivity effects that may impact on the hydro electric power generation infrastructure and activities. Policy - Minimise impacts on hydro electric generation infrastructure 12.3.2.1 To manage development and subdivision that may potentially conflict with, restrict, or compromise the existing operation of Karāpiro and Arapuni hydro-electricity generation sites and related electricity generating infrastructure and activities. Objective - Implementation of the Waikato River Vision and Strategy 12.3.3 The health and well-being of the Waikato River is restored and protected and Te Ture Whaimana o Te Awa o Waikato (the Vision and Strategy for the Waikato River) is achieved.
