He wāhanga nui ngā peera o te maha o ngā mīhini me ngā taputapu nā te mea ka whakaiti i te waku, ā, ka taea te nekeneke maeneene o ngā wāhanga hurihuri me ngā wāhanga tauutuutu. E rua ngā momo peera matua: ko ngā peera pōro me ngā peera roera. He rerekē ngā āhua, ngā rahi me ngā āhuatanga, ā, he pai mō ngā whakamahinga rerekē.
Ka whakamahia e ngā peera pōro ngā pōro whakahāngai-ake hei wāhanga hurihuri, ko ngā peera roera ia ka whakamahia ngā roera porotaka, kōniko, porowhita rānei. Ko te rerekētanga matua i waenganui i a rātou ko te horahanga pā i waenganui i ngā wāhanga hurihuri me ngā mowhiti. He hononga pūwāhi ngā peera pōro, ko te tikanga he tino iti te horahanga pā. He hononga rārangi ngā peera roera, ko te tikanga he nui te horahanga pā.
Ka pā te wāhi pa ki te mahi me te whai huatanga o te peera. He iti ake te waku me te ātete o ngā peera pōro, ko te tikanga ka taea e rātou te mahi i ngā tere teitei ake me ngā pāmahana iti ake. He nui ake te kaha kawenga me te ātete ru o ngā peera roera, ko te tikanga ka taea e rātou te tu atu i ngā kawenga ru taumaha ake, nui ake hoki.
Nō reira, he pai ake ngā peera pōro i ngā peera roera i ētahi āhuatanga, pēnei i:
• Tere: Ka taea e ngā peera pōro te whakatutuki i ngā tere hurihuri teitei ake i ngā peera roera nā te mea he iti ake te waku me te kore e taea te neke.
• Haruru: He iti ake te haruru me te wiri o ngā peera pōro i ngā peera roera nā te mea he maeneene ake, he tika ake hoki te nekehanga.
• Taumaha: He mama ake ngā peera pōro i ngā peera roera nā te mea he iti ake, he iti ake hoki ngā wāhanga hurihuri o ngā peera pōro.
• Utu: He iti ake te utu o ngā peera pōro i ngā peera roera nā te mea he māmā ake, he paerewa ake hoki ō rātou hoahoa me te hanga.
Heoi anō, kāore i te pai ake ngā peera pōro i ngā peera roera. He painga anō ō ngā peera roera, pēnei i:
• Utaina: Ka taea e ngā peera roera te tu atu i ngā kawenga radial me te axial teitei ake i ngā peera poi nā te mea he nui ake te horahanga pā, ā, he pai ake te tohatoha kawenga.
• Pakari: He kaha ake, he pumau ake hoki ngā peera roera i ngā peera pōro nā te mea he iti ake te whakapohehe me te huri i raro i te kawenga.
• Te Whakaritenga: Ka taea e ngā peera roera te whakauru i ētahi he o te whakarite me te piko o te pou me te whare nā te mea he āhuatanga whakarite-ake tō rātou.
Hei whakarāpopototanga, he rerekē ngā painga me ngā ngoikoretanga o ngā peera pōro me ngā peera roera, ā, ko te whiriwhiri i te peera e whakawhirinaki ana ki ngā whakaritenga me ngā tikanga motuhake o te tono.
