Maungaharuru is the spiritual mountain of the hapū Ngati Kurumōkihi.[2] They are the kaitiaki of Boundary Stream and the area. In 2017 the hapū were given four conservation reserves in the Hawke's Bay by the Crown as part of Treaty of Waitangi settlements. The Ngati Kurumōkihi hapū gave the reserves to the people of New Zealand (Aotearoa), three of these conservation areas are located in the Maungaharuru Range.
The Maungaharuru Ecological District is part of the Maungaharuru Range, a conservation reserve known as the Boundary Stream Mainland Island.[3] There are five tracks are maintained by the New Zealand Department of Conservatio
An organised pest management programme began in 1996 in the area by Predator Free Hawke's Bay[6] to remove the introduced mammals destroying the natural environment. Predator Free programmes aim to create an environment where native species could survive. In 2018 Titi (Cook's Petrel) were returned to their original nesting site in the range through the translocation project Poutiri Ao o Tane.[7]
The smaller Bellbird Bush Scenic Reserve, Opouahi Scenic Reserve and Thomas Bush Scenic Reserved are also located in the Maungaharuru Ranges. The rest of the range is farmland. Taraponui Peak is a part of this range, rising to 1308 metres. The range is rugged with high winds, this environment has attracted two wind farm consents for a Hawke's Bay wind farm.
In 2005 two consents were issued in the Maungaharuru area, one for the private company Hawkes Bay Wind Farm Ltd and the other by Unison Networks Limited. The two consents were purchased by Meridian Energy in 2010 and 2011 respectively and were combined as one site, these consents were extended to 2023. In August 2019, Meridian sought interest from potential contractors for the wind farm's construction.
Construction would be expected to begin in 2020.
