First Lessons in Maori
The passive termination, tia, may be used with a noun, adjective, or participle to indicate a change to the thing or condition which the simple word signifies.
Ka tamahinetia, ka wahinetia ia, she grew to girlhood and womanhood.
Aua e taparurutia te haere, do not let the rate of travelling become slow.
The passive termination may also be used with a noun to denote the bringing of the subject of the sentence under the action of what is represented by the noun.

Ka uaina ratou, they were rained upon.
This construction may even be extended to a clause, as: Ma-te-matapihitia, let it be passed through the window, from ma te matapihi, through the window.page 37
