1. Roera waituhi
Ko te roera waituhi e pā ana ki ngā moenga katoa o te pūnaha tuku waituhi. Ko te mahi a te roera waituhi he tuku i te waituhi tā ki te pereti tā i roto i te āhua taurite me te ōrite. Ka taea te wehewehe i te roera waituhi ki ngā wāhanga e toru: te kawe waituhi, te whakawhiti waituhi me te whakawhirinaki pereti. Ka kiia hoki te roera kawe waituhi he roera peere waituhi. Ka whakamahia hei tango i te waituhi taurite mai i te peere waituhi i ia wā, kātahi ka whakawhiti ki te roera whakawhiti waituhi (e kiia ana hoki he roera waituhi ōrite). Ka whiwhi te roera whakawhiti waituhi i ēnei waituhi ka tohatoha ōrite kia hanga he kiriata waituhi ōrite, kātahi ka whakawhitia ki te roera tārua pereti, ko ia te kawenga mō te tohatoha ōrite o te waituhi ki runga i te pereti. Tae noa ki tēnei wā, kua oti te mahi a te roera waituhi. Ka oti haere te tohatoha ōrite o te waituhi i roto i te tukanga whakawhiti o ētahi moenga. I roto i tēnei tukanga, hei tāpiri atu ki ngā moenga, kei reira ngā roera mārō me ngā mea e kiia nei ko ngā roera waituhi. I roto i te perehi āwhati, ka whakaritea tonutia ngā moenga me ngā roera mārō i ngā wā katoa, ka hanga he hononga ngāwari me te mārō, he pai ake tēnei whakaritenga mō te whakawhiti me te tohatoha o te waituhi. Mā te mahi a te roera waituhi ka taea te whakapakari ake i te tohatoha tuaka o te waituhi. I te wā e mahi ana, ka taea e te roera waituhi te hurihuri me te neke i te ahunga tuaka, nō reira e kiia ana ko te roera waituhi.
2. Roera whakamākū
Ko te roera whakamakuku he roera rapa i roto i te pūnaha tuku wai, he rite ki te roera waituhi, ā, ko tana mahi he kawe ōrite i te wai ki te pereti tā. Kei roto hoki i ngā roera whakamakuku te kawe wai, te tuku wai, me te tā. I tēnei wā, e rua ngā tikanga tuku wai mō ngā roera wai, ko tētahi ko te tuku wai tonu, e whakawhirinaki ana ki te roera pereti kāore he uhi weriweri wai, ā, ka tutuki te tuku wai mā te whakarerekē i te tere o te roera peere wai. Ko te tikanga tuku wai o mua he wā poto, e whakawhirinaki ana ki te roera pereti kua hipokina ki te uhi weriweri wai, ā, ka oioi te roera wai hei tuku wai. He pai te tikanga tuku wai tonu mō te tā tere-teitei, ā, kua whakakapia haeretia te tikanga tuku wai wā poto.
3. Te hanganga o te roera rapa
He rerekē te matua hurihuri me te rauemi rapa e tukuna ana ki waho, i runga i te kaupapa.
Ka taea e te hanganga matua o te roera te takoto kau, te totoka rānei, i runga i te whakamahinga. Ko te taumaha o te roera rapa te mea e hiahiatia ana i te nuinga o te wā, ka pā ki te taumaha taurite o te mīhini, kātahi ka pā ki te pumau o te wiri i te wā e whakamahia ana.
Ko te nuinga o ngā roera rapa o te mīhini tā āwhata he roera kau, he mea hanga i ngā paipa maitai kore-feng, ā, ko ngā pane o te rakau i ngā taha e rua ka whakapirihia ki ngā paipa maitai katoa. Heoi, i roto i ngā rā kei te heke mai, ka hangaia hoki i ngā rauemi kore-whakarewa, pērā i ngā kirihou kua whakapakarihia ki te muka karāhe me ētahi atu rauemi polymer, ko tā rātou kaupapa he whakaiti i te taumaha me te whakapai ake i te tere me te pumau o te mahi. Hei tauira, he tauira tono kei ngā mīhini hurihuri tere-teitei.
4. Te rauemi o te paparanga piripiri
He tata te pānga nui o te paparanga rapa ki te mahi me te kounga o te roera rapa. Me whiriwhiri ngā momo rapa rerekē mō ngā taiao whakamahinga rerekē, pērā i te ātete ki te kakahu, te ātete ki te wera, te ātete ki te makariri, te ātete ki te waikawa, te ātete ki te tote, te ātete ki te wai me ētahi atu. Kei reira anō hoki te pakeke, te ngāwari, te tae, me ētahi atu, e whakatakotoria ana hei whakautu ki te taiao whakamahinga me ngā hiahia o te kiritaki.
