I tohua a Carrie Wainwright ki te pae kaiwhakawā Kooti Whenua Māori i te 17 o Noema 2000.
Nāna i whakahaere ngā ruku-tātari i ngā rohe o Te Wairarapa ki Tararua me Whanganui me te whakahaere i ngā ruku-tātari kōhukihuki maha, otirā e pā ana ki ngā kaupapahere whakataunga Tiriti a te Karauna. Ko te otinga o ēnei ko te Pūrongo Hātepe Whakataunga mō Tāmaki Makaurau 2007. Nāna hoki i ārahi i te kōtitanga a te Taraipiunara i te Takutai Moana i te tau 2004.
I noho a Kaiwhakawā Wainwright i ētahi atu mana whakahaere mō ngā tau maha (Kooti ā-Rohe, Taraipiunara Whakamaru Hekenga) engari i hoki ki Te Rōpū Whakamana i Te Tiriti o Waitangi me te Kooti Whenua Māori i te tau 2017. E whakawā ana ia inā tata nei i ngā uiui e pā ana ki te rapu rongoā, otirā ngā tono mō ngā tūtohutanga paihere e pā ana ki ngā kaikerēme i Te Hiku o Te Ika me Te Wairarapa.
Ko Te Rau o Te Tika: the Justice Inquiry te ruku-tātari hou o te Rōpū Whakamana i te Tiriti o Waitangi e noho nei a Kaiwhakawā Wainwright. I aro pū te wāhanga tuatahi o tēnei ruku-tātari ā-kaupapa ki ā ngā mahi a te Karauna mō te tuku pūtea tautoko ki ngā kaikerēme e tū nei ki mua i te Rōpū Whakamana. I te Pēpuere o 2023, whakaputa ai a te Rōpū Whakamana i tā rātou ripoata, Whakatika ki Runga.
E tino matatau ana a Kaiwhakawā Wainwright ki te takawaenga i te Kooti Whenua Māori me Te Rōpū Whakamana i Te Tiriti o Waitangi.
