Te whakarōpūtanga noa o ngā tāpae
Ko te tāhuna he tāhuna e ārai ana i ngā awa, e aukati ana i te wai, tae atu ki te tāhuna e aukati ana i te wai i roto i ngā puna wai, i ngā awa, me ērā atu. E ai ki ngā paearu whakarōpū rerekē, ka rerekē ngā tikanga whakarōpū. Ko te hangarau te nuinga o te wā ka wehea ki ēnei momo:
1. Te Pā o te Kaha
He pā wai kaha te pā wai i hangaia ki ngā rauemi pēnei i te raima, i te kōhatu rānei, e whakawhirinaki ana ki te taumaha o te tinana o te pā wai hei pupuri i te pumau.
Te kaupapa mahi o ngā pā waikeri taumaha
I raro i te mana o te pēhanga wai me ētahi atu kawenga, ka whakawhirinaki ngā tāke taumaha ki te kaha ārai-paheke i hangaia e te taumaha o te tāke hei whakatutuki i ngā whakaritenga pumau; I te wa ano, ka whakamahia te ahotea pēhanga i hangaia e te taumaha o te tinana tāke hei whakakore i te ahotea kume i puta mai i te pēhanga wai, kia tutuki ai ngā whakaritenga kaha. He tapatoru te āhua taketake o te tāke taumaha. I runga i te papa, he tika te tuaka o te tāke, ā, i ētahi wā hei urutau ki te whenua, ki ngā āhuatanga whenua, ki te whakatutuki rānei i ngā whakaritenga o te whakatakotoranga pokapū, ka taea hoki te whakarite hei rārangi whatiwhati, hei āwhata rānei me te piko iti ki te taha whakarunga.
Ngā painga o ngā pāmu kaha
(1) He mārama te mahi hanganga, he māmā te tikanga hoahoa, ā, he haumaru, he pono hoki. E ai ki ngā tatauranga, he iti noa te tere o te pakaru o ngā tāke taumaha i roto i ngā momo tāke.
(2) He kaha te urutau ki te whenua me ngā āhuatanga whenua. Ka taea te hanga i ngā tāhuna kaha i roto i ngā āhua katoa o te awaawa.
(3) He māmā noa te whakaoti i te raruraru o te rerenga wai i te pokapū. Ka taea te hanga i ngā parenga wai taumaha hei hanganga waipuke, ka taea rānei te whakatū i ngā kōhao waikeri i ngā teitei rerekē o te tinana o te pā. I te nuinga o te wā, kāore he take ki te tāuta i tētahi atu ara waikeri, i tētahi kauhanga waikeri rānei, ā, he kiato te whakatakotoranga o te pokapū.
(4) He watea mō te hurihanga o te wai i te wā hangahanga. I te wā hangahanga, ka taea te whakamahi i te tinana o te tāhuna hei hurihanga, ā, kāore e hiahiatia he kauhanga hurihanga anō.
(5) Hanganga watea.
Ngā huakore o ngā pā wai kaha
(1) He nui te rahi o te wāhanga whakawhiti o te tinana o te tāhuna, ā, he nui hoki ngā rauemi i whakamahia.
(2) He iti te taumahatanga o te tinana o te tāhuna, ā, kāore e taea te whakamahi katoa i te kaha o te rauemi.
(3) Nā te nui o te wāhi e pā ana ki waenganui i te tinana o te tāhuna me te turanga, ka nui te pēhanga hiki i te raro o te tāhuna, ā, kāore e pai mō te pumau.
(4) He nui te rahinga o te tinana o te tāhuna, ā, nā te wera o te wai me te whakaiti i te raima i te wā hanga, ka puta he pāmahana kino me ngā taumahatanga whakaiti. Nō reira, me tino whakahaere i te pāmahana ina ringihia te raima.
2. Te Pā o te Āwhata
He hanganga anga ā-wāhi te tāwharau āwhata e piri ana ki te papa toka, e hanga ana i te āhua āwhatu pūkohu i te papa e anga atu ana ki te awa, ā, ko te āhua o te karauna āwhatu he āhua piko poutū, pūkohu rānei ki te awa.
Te kaupapa mahi o ngā tāke āwhata
He pānga āwhata, he pānga kurupae hoki tō te hanganga o te tāwharau, ā, ka pēhia te kawenga e pikau ana ki ngā taha e rua mā te mahi a te āwhata, ko te wāhanga kē ka tukuna ki te papa toka i raro i te tāwharau mā te mahi a ngā kurupae poutū.
Ngā āhuatanga o ngā tāpae āwhata
(1) Ngā āhuatanga pumau. Ko te pumau o ngā tāke āwhata e whakawhirinaki ana ki te kaha tauhohenga i ngā pito o te āwhata i ngā taha e rua, he rerekē ki ngā tāke āwhata e whakawhirinaki ana ki te taumaha-ake hei pupuri i te pumau. Nō reira, he nui ngā whakaritenga mō ngā tāke āwhata mō te whenua me ngā āhuatanga whenua o te papa tāke, me ngā whakaritenga tino pakari mō te maimoatanga turanga.
(2) Ngā āhuatanga hanganga. Nō ngā hanganga teitei te āwhata o ngā pareparenga āwhata, he kaha te kaha ki te uta me te haumaru teitei. Ina piki ake ngā kawenga o waho, ina pakaru rānei tētahi wāhanga o te pareparenga, ka whakatikatikahia ngā mahi āwhata me ngā kurupae o te tinana o te pareparenga, ka puta he tohatoha anō i te ahotea i roto i te tinana o te pareparenga. He hanganga ā-wāhi whānui te pareparenga āwhata, he mama, he pakari hoki. Kua whakaatuhia e ngā mahi hangarau he kaha hoki tōna ātete rū whenua. Hei tāpiri, i te mea he hanganga pana te pareparenga e mau ana i te pēhanga tuaka, he iti noa te nekehanga piko i roto i te pareparenga, ā, he ōrite te tohatoha ahotea, he pai ki te whakapau kaha i te rauemi. Mai i te tirohanga ōhanga, he momo pareparenga tino pai ngā pareparenga āwhata.
(3) Ngā āhuatanga o te kawenga. Kāore he hononga whakawhanui tuturu o te tinana o te tāwharau, ā, he pānga nui ngā huringa pāmahana me te whakarerekētanga o te toka papa ki te ahotea o te tinana o te tāwharau. I te wā e hoahoa ana, me whakaaro ki te whakarerekētanga o te toka papa, me te whakauru i te pāmahana hei kawenga matua.
Nā te angiangi o te kōtaha me te āhua ā-ira matatini o te tāwharau āwhata, he tino kaha ake ngā whakaritenga mō te kounga hanga, te kaha o ngā rauemi o te tāwharau, me te ārai-mimi i ērā o ngā tāwharau ā-papa.
3. Te pā o te toka whenua
