§ 61. There are no Relative Pronouns in Maori. Their place is supplied either by the position of the words forming the relative clause; or by the personal pronoun of the 3rd person singular; or again, by the use of certain particles.
§ 62. Who. When the relative in English is the subject of a verb in the relative clause:
(a) That verb may be placed immediately after the antecedent portion of the sentence without any expressed subject.
Examples.
Te tangata e hanga whare ana, the man who is house-building.
Te hoiho i kitea e taua, the horse which was seen by you and me.
(b) If the relative clause is past or future, the construction mentioned in [§ 49] may be used; the pronoun of the third person singular serving for all persons and numbers.
Examples.
Ko Hemi te tangata nana i patu taku witi, the man who threshed my wheat was Hemi.
Ko nga tangata enei nana i tahu te ngahere, these are the men who set the forest on fire.
