Waitoki graduated from the University of Waikato with a Postgraduate Diploma in Clinical Psychology, becoming a member of the New Zealand Psychological Society's National Standing Committee on Bicultural Issues in 1998.[3] She also has a PhD from the same university, completed in 2012.[4]
From 2002 until 2009, Waitoki was a board member of the New Zealand Psychologists Board.[3] Waitoki was one of the driving forces of the National Māori Graduates of Psychology Symposium, an event held in November 2002.[5][6] In the early 2010s, Waitoki was the Bicultural Director of the New Zealand Psychological Society.[3]
In 2016, Waitoki published a book entitled Te manu kai i te mātauranga: Indigenous psychology in Aotearoa/New Zealand, a compilation of 18 Māori psychologists' opinions on a single case study.[7][8]
Since 2018, Waitoki has been an investigator in several large-scale projects. In 2018, she became the lead investigator for a Marsden grant-funded study involving Mātauranga Māori and Indigenous psychology,[9][1] and in the following year received an additional Marsden grant, as a member of a multidisciplinary team researching Waikato wetland pā using carbon–14 wiggle-match dating (WMD) and dendrochronology to give more precise dates to wetland pā pallisades.[10] In 2019, Waitoki proposed the creation of a Kaupapa Māori-based clinical psychology programme in New Zealand, training Māori clinicians with a Māori world view, in order to address inequalities in the New Zealand mental health system.[11]
Waitoki received two grants from the Ministry of Business, Innovation and Employment in 2020. The first was for a project to investigate Māori maternal health inequalities, entitled Raranga, raranga taku takapau: hapū ora for tamariki, investigating the use of Mātauranga Māori and tikanga to improve the wellbeing of mothers.[12] The second, Working to End Racial Oppression (WERO), is a project examining the impacts of racism, leading towards the development of tools to measure and combat institutional racism.[13][14]
In November 2022 Waitoki was awarded the Te Puāwaitanga Research Excellence Award for eminent and distinctive contribution to Te Ao Māori and indigenous knowledge by the Royal Society Te Apārangi, for her work "indigenising the psychology profession".[17]
