(2) Ko te mata hiri kaore i te ngawari ki te kakahu me te pakaru, te pai o te hiri, te tuwhera me te kati i waenga i te kōpae takirere me te mata hiri o te tinana takirere me te kore e paheke whanaunga, na reira karekau te kakahu me te pakaru, he pai te mahi hiri, te roa o te mahi.
(3) i te wa e whakatuwhera ana me te kati, he iti te whiu o te kōpae, na reira he iti ake te teitei o te paera o te ao i te paera o te kuaha, engari he roa ake te roa o te hanganga i te paera kuaha.
(4) he nui te taipana whakatuwhera me te kati, he uaua te whakatuwhera me te kati, ko te wa whakatuwhera me te kati te tumuaki.
(5) he nui te parenga o te wai, na te mea ko te hongere waenga i roto i te tinana takirere he tortuous, he nui te parenga wai, he nui te kai mana.
(6) ka iti ake te pehanga Pn i te ahunga o te rere reo i te 16Mpa ranei, ko te tikanga kei raro te awa, ka rere te reo mai i te ahunga o raro o te kōpae takirere;Te pehanga ingoa Pn ≥ 20Mpa, i te nuinga o te waa ka whakamahi i te aurere, te rere reo mai i te ahunga o te kōpae.Hei whakanui ake i te kaha hiri.I te wa e whakamahia ana, ka taea anake te rere o te reo takirere tapahi ki te huarahi kotahi, kaore e taea te whakarereke i te ahunga o te rere.
(7) i te wa e puare katoa ana, he maha nga wa ka pakaru te kōpae.
Ko te tuaka o te kakau takirere o te takirere ao e tika ana ki te mata hiri o te nohoanga takirere.He poto te whiu o te kakau tuwhera/kati, a he tino pono te mahi tapahi, na te mea e tika ana tenei takirere mo te tapahi-a-waenga, te whakahaere me te whakamahi maana.
