He rite tonu te hanga o ngā peera roera ki ngā peera poi, he hononga raina te hononga o ngā peera roera, kaua ki te hononga pūwāhi, kia nui ake ai te kaha me te ātete ru. He maha ngā āhua o ngā roera, arā, he porotaka, he porowhita, he whakarara, me te ngira. He iti noa ngā kawenga pana ka taea e ngā peera roera porowhita te whakahaere. Ka taea e ngā peera roera porowhita te whakahaere i te kore taunga me te pana nui ake, ā, ina takiruahia, ka pana ki ngā taha e rua. Ka taea e ngā peera roera whakarara te whakahaere i ngā kawenga pana nui. Ko ngā peera ngira, he momo peera roera porowhita, ka taea te whakahaere i ngā kawenga radial teitei mō tō rātou rahi, ā, ka taea te hanga hei peera pana roera ngira.

Kei te wātea ngā peera roera hei hoahoa tāpiri-katoa, ā, tata tonu ka rite ngā peera ngira ki tēnei momo. He tino whai hua ngā peera ngira mō ngā nekehanga tauutuutu, engari ka nui ake te waku nā te mirimiri o te roera-ki-te-roera.

Mēnā e whakamahia ana ngā peera roera porotaka ki ngā toki he koki te tūnga, he pai ake te whakamahi i ngā peera roera poto e rua e anga tahi ana, kaua ki te whakamahi i te peera roera roa kotahi.

Te Kōwhiri i tētahi Pōro, i tētahi Whero rānei
Ko te tikanga whānui, ka whakamahia ngā peera pōro i ngā tere teitei ake me ngā kawenga mama ake i ngā peera roera. He pai ake te mahi a ngā peera roera i raro i te taumahatanga ru me te pānga.

Ko ngā peera pōro he mea hoko noa hei huihuinga, ā, ka whakakapia noa hei wāhanga. He maha ngā wā ka taea te wetewete i ngā peera roera, ā, ka whakakapia takitahi te kawe roera me ngā roera, ngā reihi o waho, o roto rānei. Ka whakamahia e ngā waka taraiwa-wira-muri ēnei whakaritenga mō ngā wira o mua. Ko te painga o tēnei hoahoa ko te taea te whakaiti i ngā reihi kia uru ki ngā pou me ngā whare hei hanga huihuinga pumau me te kore e tūpono ka pakaru ngā roera.

He paerewa ngā peera pōro rarangi kotahi, ā, ka taea te whakamahi tauwhitiwhiti i waenga i ngā kaihanga. Kāore i te tino paerewahia ngā peera roera, nō reira me tirotiro e te kaiwhakatakoto whakaaro te rārangi ingoa a te kaihanga ki te whiriwhiri i tētahi e tika ana mō te tono.

He nui te āputa o roto o ngā peera porotaka e hangaia ana. Ko te korenga o te tūnga e pana noa ana i te pōro ki waho o tōna tūranga, e tango ana i tēnei āputa o roto, kāore e nui te pānga ki te roa o te oranga o te peera. He tairongo ake ngā peera porotaka ki te korenga o te tūnga koki. Hei tauira, ko te peera pōro e rere ana i te tere taurite me te taunga tino ngāwari, ka pai pea te mahi me te korenga o te tūnga koki tae atu ki te 0.002 ki te 0.004 inihi/inihi i waenganui i te peera me te pou. Ki te whakataurite, ka raru pea te peera porotaka porotaka mena ka neke ake te korenga o te tūnga i te 0.001 inihi/inihi. Ko te tikanga, ka whakaratohia e ngā kaihanga he whānuitanga o te korenga o te tūnga koki e whakaaetia ana mō ā rātou peera takitahi.
