Kei te piki haere te hiranga o te pūngao waiariki hei pūtake pūngao whakahou nā te mea ka taea e ia te whakarato hiko pumau (pūmau), he iti noa ngā tukunga, me te wātea o te pūngao kāore e pāngia e te huarere. Heoi, ko ngā āhuatanga hihiri o ngā puna waiariki, ngā mōrearea o te waikura me te tauine, me ngā tono mō te mahi pono, e tohu ana me āta hangaia ngā pūnaha whakahaere aunoa e ngā tipu hiko waiariki. Ko te hoahoa o ngā pūnaha whakahaere aunoa ehara i te mea ko te pupuri noa i te haere tonu o te tukanga engari ko te arotau i te whai huatanga, te whakaroa i te roa o te ora o ngā taputapu, te whakarite i te haumaru, me te tutuki i ngā paerewa taiao.
1. He Tirohanga Whānui mō ngā Tukanga Pūngao Ā-Wharewha
I te nuinga o te wā, ka whakamahia e ngā tipu hiko waiariki te waiariki mai i ngā puna whakaputa. Ka taea e tēnei wai te mamaoa maroke, te ranunga mamaoa-wai (mamae tere), te wai wera rānei (huringa rua/ORC). I muri i te hurihanga o te pūngao wera hei pūngao miihini e te tāwhana, kātahi ka hiko mā te whakaputa hiko, ka werohia anō te wai ki roto i te puna wai mā te puna werohanga hei pupuri i te pumau o te pūtake. He maha ngā taurangi me whakahaere puta noa i tēnei mekameka tukanga, pērā i te pēhanga wehewehe, te pāmahana tote, te tere rere o te mamaoa, te taumata waipūhau, te korehau waipūhau, me te kounga o te mamaoa. Ko te pūnaha whakahaere aunoa te "roro" e whakarite ana i ēnei taurangi katoa kia pai ai te mahi a te tipu me te haumaru.
2. Ngā Whāinga Matua o ngā Pūnaha Whakahaere Aunoa
