Tereki has spent the larger part of his working life in iwi roles and Māori organisations, mostly in Māori health and the primary/community sectors. He has held a number of executive roles including Manukura Hauora (Health Lead) for Te Rūnanga o Ngāti Whātua, and is the former Chief Executive of two Māori-led PHOs. His previous governance experience has included sitting on the boards of private GP practices, iwi partnership organisations, and appointments to the former DHB community and public health and Māori health advisory committees. Tereki is also currently the Chair of Te Taumata Hauora o Te Kahu o Taonui, the Iwi Māori Partnership Board (IMPB) in the North stretching from the Tāmaki estuary in Auckland, mai ki te Rerenga Wairua (to the top of the North Island).

Tereki brings a lived experience to the Board as a stroke survivor and is also passionate about achieving equitable outcomes for Māori and other population groups ‘under-served’ by the health system. His other passion is ‘hanging’ with his whānau, especially his mokopuna.
