W. L. Williams, First Lessons in the Maori Language…
“ Every active verb is connected with its object, or the thing acted upon, by either of the prepositions i, or ki; some verbs requiring one, some the other, and some again [37] taking either. These prepositions in some cases may be translated by an English preposition; but in most cases they merely represent the connexion between the verb and its object, and may therefore be called transitive prepositions.Every passive verb is connected with the agent by the preposition "e", which is rendered "by" in English. ”
