Ground-source heat pumps (GSHPs) are an established technology, capable of delivering efficient heating and cooling utilising the immense renewable energy stored in the ground, ground water or surface water. They are being recognised as an alternative to fossil fuel systems and can offer significant reductions in the overall CO2 emissions. GNS Science Māori Strategy seeks to identify the opportunities of GSHP technologies as a consideration for housing or marae development.

This technology has much to offer communities, particularly in rural areas because resource use is relatively benign. Also, this technology has much to offer Māori and the important rural marae that fulfill a crucial role in New Zealand communities.

In this paper, we describe a comprehensive framework for ground-source heat pump technologies in rural Māori communities aiming at societal acceptance of resource use and the technology associated with ground-source heat pumps. For these communities, resource utilisation must be consistent with long-term Māori custodial responsibilities. The framework is developed and tested with Ngati Rangiwewehi and the Awahou Marae on the shores of Lake Rotorua.
