rauemi arae hangaia ana i ngā roa paerewa o te 30 putu, 39 putu, 60 putu rānei, ahakoa ka taea hoki te hanga i ngā reri roa ake mō ngā kaupapa motuhake. Ko te momo reri maitai tino noa e whakamahia ana i roto i ngā ara rerewē e mōhiotia ana ko te reri papatahi, he papatahi te turanga me ngā taha koki e rua. Ko te taumaha o te reri, e mōhiotia ana ko tōna "pauna", ka rerekē i runga i ngā whakaritenga motuhake o te ara rerewē.
Te tukanga whakaputa oara rerewēhe maha ngā mahi e whai wāhi ana, tae atu ki:
- Te whakarite rauemi mata: Ka tīmata te hanga reri maitai mā te whiriwhiri me te whakarite i ngā rauemi mata, ko ngā pereki maitai kounga teitei te nuinga. Ka hangaia ēnei pereki mai i te rino me ētahi atu tāpiringa, pērā i te kōhatu me te kōka, ka rewahia i roto i te oumu pupuhi hei hanga rino rewa.
- Te whakarewa tonu: Kātahi ka whakawhitia te rino rewa ki tētahi mīhini whakarewa tonu, ka ringihia ki roto i ngā pokepoke hei hanga i ngā miro roa tonu e kiia nei ko ngā pire. He tapawhā te āhua o ēnei pire, ā, koinei te rauemi tīmatanga mō temaitai ara rerewētukanga whakaputa.
- Te whakamahana me te hurihuri: Ka whakamahanahia anō ngā pereki i roto i te oumu ki te pāmahana e ngāwari ai te hanga me te hurihuri. Kātahi ka tukuna mā roto i tētahi raupapa mira hurihuri, e pēhi nui ana kia hangaia ngā pereki kia rite ki te āhua rēri e hiahiatia ana. Ko te tukanga hurihuri he maha ngā tukuruatanga o te tuku i ngā pereki mā roto i ngā mira hurihuri kia āta hangaia ai hei rēri.
- Te whakamatao me te tapahi: I muri i te tukanga hurihuri, ko temaitai ara rerewēka whakamataohia, ka tapahia ki te roa e hiahiatia ana. I te nuinga o te wā ka tapahia kia rite ki te roa o te 30 putu, 39 putu, 60 putu rānei, ahakoa ka taea hoki te hanga i ngā reri roa ake mō ngā kaupapa motuhake.
- Tirotiro me te maimoatanga: Ka tirotirohia ngā reri kua oti kia tino tutuki ai ngā paerewa me ngā whakaritenga ahumahi. He maha ngā whakamātautau, pērā i te ine i ngā āhuatanga, te tātari matū, me te whakamātautau miihini, ka mahia hei manatoko i te kounga me te pono o ngā reri. Ka tautuhia, ka arohia hoki ngā hapa, ngā hapa rānei.
- Te maimoatanga mata: Hei whakapakari i te pakari me te ātete ki te waikura o ngā reera, ka taea te whakahaere i ngā tukanga maimoatanga mata. Kei roto i tēnei ko te paninga o ngā paninga tiaki, pērā i te peita ārai-waikura, te whakapūkara rānei, hei ārai i te waikura me te waikura, kia roa ake ai te ora o ngā reera.
- Te tirotiro whakamutunga me te takai: Kia oti ngā rēri te tukatuka me te paahi i te tirotiro whakamutunga, ka ata takaihia kia taea ai te kawe ki ngā papa hanga rēri. Kua hangaia te takai hei tiaki i ngā rēri mai i ngā kino i te wā e kawe ana.
Ngā Āhuatanga
ara tereinahe wāhanga nui o ngā ara rerewē, ā, he maha ngā āhuatanga matua:
1. Kaha me te Pakari: He mea hanga ngā reera maitai ki te maitai kounga teitei, e homai ana he kaha me te pakari tino pai. He mea hanga kia tu atu ki ngā kawenga taumaha, ki ngā pānga tonu, me ngā āhuatanga huarere kino, me te kore e nui te whakarerekētanga, te pakaru rānei.
2. Te Kaha Pikau Utauta: He mea hanga ngā reri maitai hei tautoko i te taumaha o ngā tereina me ā rātou utanga. Ka taea e rātou te kawe i ngā kawenga taumaha, ā, ka tohatoha ōrite te taumaha, ka whakaiti i te tūponotanga o te pakaru o te ara, te whakarerekētanga rānei.
3. Ātete ki te Pakaru: He tino ātete ngā reri maitai ki te pakaru me te pakū. He mea nui tēnei nā te mea ka rere tonu ngā tereina i runga i ngā reri, ka puta te waku me te pakaru i te roanga o te wā. Ko te maitai e whakamahia ana i roto i te hanga reri he mea whiriwhiri motuhake mō tōna kaha ki te ātete ki te pakaru me te pupuri i tōna āhua i roto i ngā wā roa o te whakamahinga tonu.
4. Te Tika o ngā Ahu: Ka hangaia ngā reri maitai ki ngā paerewa āhu kia tino hototahi ai, kia maeneene ai hoki te mahi me ētahi atu wāhanga reriwe, pērā i ngā hononga reriwe, ngā here whakawhiti, me ngā whakapiri. Mā tēnei ka taea te nekeneke maeneene o ngā tereina i te ara, ā, ka whakaiti i te tūponotanga o te he o te ara, te whakararuraru rānei.
