(Te Kōhure Textbook (Ed. 2): 43;)
Ko te wawata, ko te uaratanga nui kia puta i tēnei tau tētahi kohikohinga kīwaha, kīrehu, arā ngā āhuatanga reo kua kaha nei te ngaro i waenga i te nuinga o ngā iwi (HM 4/1997:4). / The hope and the great desire is that a collection of colloquialisms and idioms, that is the aspects of the language that have long been missing amongst most of the tribes, will appear this year.
