I roto i ngā āhuatanga noa, he ātete-hau te pūnaha whakamatao i roto i te waeine whakamatao kawe taiaho tere rawa, ā, ka taea te whakamatao tika. Heoi, ina puta he momo pakaru, ā, kāore te pūnaha whakamatao i te ātete-hau, ka iti iho te pēhanga taiao i te pēhanga o te pūnaha whakamatao. I tēnei wā, ka rere te hauhautanga i waho o te pūnaha whakamatao. Ā, e mōhio ana tātou, ki te kore he hauhautanga o te pūnaha whakamatao, e kore te waeine whakamatao iti tere rawa e whakamatao tika. Nō reira, e taunakihia ana kia kimihia, kia whakarewahia hoki te pūwāhi turuturu, ka whakakī anō ki te nui tika o te hauhautanga.
Whai muri i te 19 tau o te whanaketanga, ka whakatūhia e mātou he pūnaha kounga hua pakari, ā, ka whakaratohia he ratonga whai muri i te hoko kua tino whakapumautia. Neke atu i te 90 ngā tauira pouaka whakamatao wai paerewa me te 120 ngā tauira pouaka whakamatao wai hei whakaritenga. Me te kaha whakamatao mai i te 0.6KW ki te 30KW, ka taea te whakamahi i ā mātou pouaka whakamatao wai hei whakamatao i ngā momo pūtake taiaho rerekē, ngā mīhini tukatuka taiaho, ngā mīhini CNC, ngā taputapu hauora, ngā taputapu taiwhanga me ētahi atu.
