Ko te Ture o Ahitereiria mai i te tau 1901, i te wā i kore ai nga whenua o te Emepaea o Ingarangi e noho rangatira ana, ā, kāore e whakamahia ana te kupu "kaiārahi kāwanatanga". I te mea he mana ā-ture a Ahitereiria, ka whakaahuatia e ngā puna kāwanatanga me ngā puna mātauranga te Kuini hei kaiārahi kāwanatanga. I roto i te mahi, ka wehewehea te tūranga o te rangatira kāwanatanga o Ahitereiria i waenganui i ngā tāngata e rua, te Kuini o Ahitereiria me te Kawana-Tianara o Ahitereiria, e tohua ana e te Kuini i runga i te tohutohu a te Pirimia o Ahitereiria. Ahakoa i roto i ngā āhuatanga maha ko te Kawana-Tianara te māngai o te Kuini, ā, ka whakamahi i ngā mana ā-ture maha i runga i tōna ingoa, he maha ngā mana nui i runga i a rātou anō. Ko te kawana-tianara e tohu ana i Ahitereiria i te ao whānui, e tuku ana i ngā haerenga me ngā haerenga kāwanatanga.
