Maori values and uses of low temperature geothermal in Tauranga Moana

Abstract

The Tauranga Geothermal System is a low temperature geothermal system in the Bay of Plenty Region, with temperatures ranging from 30°C to 77°C. The geothermal heat is used for commercial, domestic and municipal space and water heating, and bathing. With advancements in heat pump technology and a focus on renewable low carbon energy, there is growing interest in the use of low-temperature geothermal resources. As a potential accessible source of geothermal heat, the Tauranga Geothermal System is increasingly seen as a value proposition for social and economic development in the region.
To help manage the system, Bay of Plenty Regional Council (Council) is developing a Tauranga Geothermal System Management Plan, building on previous work to characterise the system, reservoir modelling, iwi and hap? management plans, and an economic assessment of geothermal values in the region. The Council is also working towards greater partnership with M?ori in geothermal management, and to ensure that M?ori are well positioned to benefit from geothermal development. This paper describes the outcomes of targeted engagement with M?ori on the Tauranga Geothermal System, to identify values associated with the geothermal system, and M?tauranga M?ori (M?ori knowledge) on the health of the resource. Opportunities and strategies to build iwi and hap? capabilities about low temperature geothermal, and its use for social and economic wellbeing, such as Papak?inga housing, are also explored.
