1. Paipa maitai kore-whakarewa wera
Ko te hurihuri wera e pā ana ki te whakamahana i te maitai ki te pāmahana e tika ana, me te hanga i tētahi paipa maitai kore hononga mā te maka tonu me te hurihuri. Ko ngā āhuatanga o te paipa maitai kore hononga hurihuri-wera he kaha teitei, he kirihou pai, he mahi whakarewa hoki nā te mea he tino pai te āhua kirihou o ngā kakano i roto i te paipa maitai i muri i ngā tukanga hurihuri maha. Mō te āhua tuku, ka wehea ngā paipa maitai kore hononga hurihuri-wera ki ngā āhua e toru: te kiri mangu, te kiri maeneene me te kiri huri. Ko te kiri mangu te āhua kāore he maimoatanga mata, ko te kiri maeneene te āhua i muri i te maimoatanga mata, ā, ko te kiri huri te āhua. Ko te āhua oro pāmahana teitei.
2. Paipa maitai kore-whakamahanatia
Ko te whakamahana i te paipa maitai kore hononga e pā ana ki te whakamahana, te whakamarumaru me te whakamatao i te paipa maitai kore hononga kia whai āhuatanga ā-tinana, ā-tinana hoki. Ko te āhua tuku o ngā paipa maitai kore hononga kua whakamahanahia ka whakamahanahia, ka whakatikatikahia rānei. Ko te āhua whakamahana e pā ana ki te whakamahana i te paipa maitai ki tētahi pāmahana, ka pupuri mō tētahi wā, kātahi ka whakamatao mārire ki te pāmahana rūma; ko te āhua whakatikatika e pā ana ki te whakamahana i te paipa maitai ki tētahi pāmahana, ka pupuri mō tētahi wā, kātahi ka whakamataohia ki te wai, ki te hinu rānei kia kaha ake ai, kia pakeke ake ai.
3. Te rerekētanga i waenga i ngā paipa maitai kore-whakakorikori wera me ngā paipa maitai kore-whakakorikori wera
E rua ngā tukanga rerekē o te hurihuri wera me te maimoatanga wera i roto i te hanga paipa maitai kore hononga, ā, he rerekētanga anō hoki te āhua o te tuku. He pai te kirihou o te paipa maitai kore hononga hurihuri wera, te mahi whakarewa me te kaha teitei, ā, he pai mō ētahi ātete pēhanga, ātete wera, ātete waikura me ētahi atu mara. He nui ake te pakeke, te kaha me ētahi atu āhuatanga miihini o ngā paipa maitai kore hononga kua rongoatia wera i muri i te whakamahana, i te maimoatanga whakataurite rānei, ā, he pai mō ngā mara hangarau e hiahia ana ki te tu atu ki ngā pēhanga teitei me ngā kawenga taumaha.
I te poto, i te wā e whiriwhiri ana i ngā paipa rino kore hononga, me whiriwhiri i runga i ngā hiahia whakamahinga tūturu me te āhua tuku o ngā paipa rino kore hononga. I te wa ano, kia aro ki te hoko hua i hangaia e ngā kaihanga noa kia tutuki ai te kounga me te mahi ki ngā whakaritenga.
