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 roera-ki-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 te kaiwhakatakoto i te rārangi ingoa a te kaihanga hei 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.
