1. Me whai te hanganga o te kohatu pakaru pungarehu rere sima i ngā whakaritenga hoahoa me ngā āhuatanga o te papaanga, ā, me tutuki hoki ki ngā paerewa ā-motu o nāianei: (1) He pai ngā puranga keri porowhita roa me te whakakī wai mō ngā oneone piripono, ngā oneone paru, me ngā turanga whakakī horihori i runga ake i te taumata wai whenua; (2) He pai ngā puranga keri pakitara paru me te whakakī wai mō ngā oneone piripono, ngā oneone paru, ngā oneone onepu, ngā oneone whakakī horihori, ngā oneone kirikiri, me ngā paparanga toka kua pakaru; (3) He pai ngā puranga keri porowhita roa me te pēhi paipa i ngā rauemi whakauru mō ngā oneone piripono, ngā oneone paru, ngā oneone onepu, me ētahi atu turanga, tae atu ki ngā wāhi he tino whakaritenga mō te whakahaere i te haruru me te parahanga paru; (4) He pai ngā puranga totohu paipa me te whakakī wai mō ngā oneone piripono, ngā oneone paru, ngā oneone whakakī horihori, me ngā paparanga onepu matotoru kāore i te piripono.
2. Haunga te whakatutuki i ngā paerewa ā-motu o nāianei, ko te hanganga o ngā puranga rauemi whakauru porowhita roa me ngā paipa pēhanga papu ā-roto, me ngā puranga totohu me ngā puranga whakakī, me tutuki hoki ēnei whakaritenga: (1) I te wā o te hanganga, me whakarite te rauemi whakauru kia rite ki te ōwehenga hoahoa. Ko te nui o te wai e tāpirihia ana ki te mīhini whakaranu ka whakahaeretia e te totohu o te rauemi whakauru. Mō te keri porowhita roa me te hanganga puranga rauemi whakauru pēhanga papu ā-roto o ngā paipa, me 180-200mm te totohu, engari mō te hanganga puranga totohu me te puranga whakakī, me 30-50mm te pai. I muri i te hanganga o te puranga, kaua e neke ake i te 200mm te matotoru o te paru e mānu ana i te tihi o te puranga; (2) I muri i te keri ki te hohonu kua whakaritea, mō te keri porowhita roa me te hanganga puranga rauemi whakauru pēhanga papu ā-roto o ngā paipa, me whakahaere tika te wā mō te hiki i te tokotoko keri. Me ōrite te nui o te rauemi whakauru e pupuhihia ana ki te tere tō o te paipa kia mau tonu ai te teitei o te rauemi whakauru i roto i te paipa. Mena ka tūtaki koe ki te onepu mākū, ki ngā paparanga paru mākū rānei, kaua te papu e mutu kia tatari kia puta mai he rauemi anō. Mō te totohu paipa me te hanga puranga whakatō, me whakahaere te tere kukume paipa i te tere raina toharite, me te tere kukume paipa kia whakahaeretia i te 1.2-1.5m/min. Mena ka tūtaki koe ki te paru, ki te oneone paru rānei, ka taea te whakaiti i te tere kukume paipa; (3) I te wā hanga, me teitei ake te teitei o te tihi puranga i te teitei o te tihi puranga kua hoahoatia. Me whakatau te teitei i runga ake i te teitei o te tihi puranga kua hoahoatia i runga i te tawhiti o te puranga, te āhua o te whakatakotoranga puranga, ngā āhuatanga whenua o te papa, me te raupapa hanganga puranga, ko te tikanga kaua e iti iho i te 0.5m; (4) I te wā hanga puranga, me tango ngā tauira o te rauemi whakaranu hei hanga poraka whakamātautau. Me whakaputa e ia mīhini tētahi huinga (3 poraka) o ngā poraka whakamātautau (poraka me te roa taha o te 150mm) ia rā, me whakamaroke paerewa mō te 28 rā, ā, me ine i tō rātou kaha pēhi; (5) I te wā hanga o te puranga ringihanga paipa, me tirotiro te awe o ngā puranga hou kua hangaia ki ngā puranga kua hangaia kē. Ina kitea te puranga e whati ana, e wetewete ana, me pēhi takitahi ngā puranga hangarau ki te pēhanga tūmau. Ko te roa o te pēhanga tūmau he 3 meneti te roa, ā, me pēhi te pēhanga tūmau kia honoa ai ngā puranga whati.
3. Ka taea te keri i te poka turanga o te turanga hiato mā te ringa, mā te mīhini rānei, mā te whakakotahitanga rānei o ngā tikanga ā-ringa me ngā tikanga mīhini. Ina whakakotahihia te keri mīhini me te keri ā-ringa, me whakatau te matotoru o te keri ā-ringa kua rāhuitia mā te keri i te papaanga kia kore ai te wāhanga pakaru i puta mai i te keri mīhini e iti iho i te teitei o te raro o te turanga, ā, kia kore ai te oneone i waenganui i ngā puranga e whakakorikoria.
4. Me whakamahi te tikanga whakakīkī pūmau mō te whakatakoto i te paparanga urunga. Mēnā he iti te nui o te wai i roto i te oneone i waenga i ngā puranga i raro i te mata o raro o te turanga, ka taea hoki te whakamahi i te tikanga whakakīkī hihiri.
5. I te wā e hangaia ana, ko te rerekētanga e whakaaetia ana mō te roa o te puranga he 100mm, ko te whānui o te puranga he 20mm, ā, ko te poutū he 1%. Mō te turanga katoa me ngā puranga e whakatakotoria ana i te rarangi kotahi, ko te rerekētanga e whakaaetia ana mō ngā tūranga puranga he 0.5 ngā wā o te whānui o te puranga; mō te turanga rīpene, ko te rerekētanga e whakaaetia ana mō ngā tūranga puranga poutū ki te tuaka he 0.25 ngā wā o te whānui o te puranga, ā, mō te ahunga i te tuaka, he 0.3 ngā wā o te whānui o te puranga. Kaua te rerekētanga e whakaaetia ana mō ngā tūranga puranga i roto i te rarangi kotahi o ngā puranga e neke ake i te 60mm.
