Scott Summerfield
He mokopuna au o Te Waipounamu, ko Tangata Tiriti ahau. E noho ana au ki te Wairarapa īnaianei.
My current work is focused on supporting councils to understand and take action on their Te Tiriti o Waitangi responsibilities. This mahi is built on a platform of experience working across Treaty settlement negotiations, local government Te Tiriti partnerships, systems and policy development, as well as central government Te Tiriti partnership management. My passion for supporting improvement in the exercise of kāwanatanga and upholding Te Tiriti o Waitangi has also extending into academic areas, and I hold a Masters in Māori Studies.
I’m an unashamed fan of the impact and potential of local government with over a decade of experience working across a wide range of councils across the motu. This experience has also shown me the significant challenges facing councils, and the humble and dedicated efforts of kaimahi across the sector to address these challenges on behalf of their communities.
I’m really pleased to be able to partner with Taituarā on this programme to support local government Te Tiriti practice that is specific to the challenges, opportunities and aspirations currently facing local government. It’s also a time of great disruption in this space – and how councils navigate changes in their governing and legislative arrangements while upholding and growing their relationships with mana whenua really matters.
I live in eastern Wairarapa with my husband and badly behaved dog. We spend our time gardening, growing excessive amounts of fruit and vegetables (there’s a chance workshops held in harvest months will be beneficiaries of this mahi), and a long-term wetland restoration project.
