He momo ngongo maitai kore hononga te ngongo koranu, e wehea ana ki te ngongo koranu hanganga kore hononga me te ngongo koranu ātete wera pēhanga teitei. He rerekē te nuinga i ngā paerewa whakaputa me te ahumahi ngongo koranu, ka rerekē ngā āhuatanga miihini o ngā ngongo koranu kua whakamahanahia me te whakamātao. Ka tutuki i ngā tikanga tukatuka e hiahiatia ana. He teitei ake tana mahi i te paipa maitai kore hononga noa, he nui ake te Cr i roto i te hanganga matū, nō reira he ātete pāmahana teitei, he ātete pāmahana iti me te ātete waikura. Kāore he koranu, he iti rānei te koranu i roto i ngā ngongo koranu kore hononga waro noa. He whānuitia te whakamahinga o te ngongo koranu i roto i te hinu, te rererangi, te matū, te hiko, te poiha, te ope taua me ētahi atu ahumahi, nā te mea he rerekē ngā āhuatanga miihini o te ngongo koranu, he ngāwari ki te whakarerekē.

Ko ngā paipa rino koranu te nuinga o te wā e whakamahia ana i roto i ngā tipu hiko, ngā tipu hiko karihi, ngā kohua pēhanga teitei, ngā whakamahana pāmahana teitei, ngā whakamahana anō me ētahi atu paipa me ngā taputapu pēhanga teitei me te pāmahana teitei. He mea hanga ki te maitai waro kounga teitei, te maitai hanganga koranu me te maitai ātete wera kore waikura mā te huri wera (whakaputa, whakawhānui) te huri matao rānei (tuhi).
