Ko te peera pōro noa he ara rere ā-roto, ā-waho hoki, he maha ngā wāhanga porowhita e wehea ana e te kaikawe, ā, he maha ngā wā, he parepare me/ngā hiri rānei kua hangaia hei pupuri i te paru me te hinu ki roto. Ina tāutahia, ka pēhia mārire te peera ā-roto ki runga i te pou, ā, ka puritia te peera o waho ki roto i te whare. Kei te wātea ngā hoahoa mō te whakahaere i ngā kawenga radial parakore, ngā kawenga axial (pana) parakore, me ngā kawenga radial me axial whakakotahi.

E whakaahuatia ana ngā peera pōro he hononga pūwāhi; arā, ka pā ia pōro ki te reihi i roto i tētahi wāhi iti rawa - he pūwāhi, i roto i te ariā. Kua hangaia ngā peera kia kore ai te iti o te huringa o te pōro i a ia e hurihuri ana ki roto, ki waho hoki i te rohe kawenga e neke ake i te pūwāhi tuku o te rauemi; ka hoki te pōro kua tangohia ki tōna āhua taketake. Kāore he mutunga kore o ngā oranga o ngā peera pōro. I te mutunga, ka pakaru rātou i te ngenge, te pakaru, te maha atu rānei o ngā take. Kua hangaia i runga i te pūtake tatauranga me te oranga whai hua e tumanakohia ana kia pakaru tetahi tau i muri i te maha o ngā hurihanga kua whakaritea.

E tuku ana ngā kaihanga i ngā peera porowhita kotahi-rārangi i roto i ngā raupapa e whā i runga i te whānuitanga o ngā rahi pūwero paerewa. Kua hangaia ngā peera whakapā koki hei tu atu i te kawenga tuaka i te taha kotahi, ā, ka taea te takirua hei whakahaere i te kawenga pana i ngā taha e rua.

He mea nui te tūnga o te pou me te peera ki te roa o te ora o te peera. Mō te kaha whakatikatika he nui ake, ka whakamahia ngā peera whakatikatika-ake.

Hei whakanui ake i te kaha kawenga-ā-rohe, ka tangohia te kawe peera, ā, ka whakakīia te āputa i waenga i ngā reihi ki te maha o ngā pōro e uru ana—te mea e kiia nei ko te peera tāpiri-katoa.

I ngā tono nui e pā ana ki te rere o te toki—hei tauira, ko ngā miro taputapu mīhini—ka taea te utaina i mua i ngā peera hei tango i te āputa i roto i te huihuinga peera kua tino pai te manawanui.
