Ka neke ake, ka heke iho te tokotoko ngote i roto i ngā ngongo, nā te āhua pīngore o te tokotoko ngote, ka ngāwari te waku i te pakitara o te tokotoko me te ngongo hinu, ā, ka ngāwari te whati o te tokotoko ngote. He kaha te ngāwari o te pūwhakapū o te tokotoko ngote. Mā te pā ki te pakitara ngongo ka taea te whakaiti i te waku o te tokotoko me te ngongo, ā, ka taea te roa ake te roa o te mahi papu. Ka honoa te pūwhakapū ki te tokotoko ngote, he nui ake te diameter o waho o te pūwhakapū i te diameter o waho o te hononga, kia taea ai te mahi pūwhakapū. He mea hanga te pūwhakapū ki te rauemi kaha-teitei, ā, ka pā ki te ngongo hei whakaiti i te karawarawa kia tutuki ai te kaupapa o te ārai-karawarawa.
