Ko te pokepoke whakarewa e pā ana ki te pokepoke e whakamahia ana hei hanga i ngā whakarewa i roto i te tukanga whakarewa. Ka honoa ngā pokepoke whakarewa ki te tukanga whakarewa, ko te nuinga kei roto ko ngā pokepoke whakarewa taumaha, ngā pokepoke whakarewa pēhanga teitei (ngā pokepoke whakarewa mate), ngā pokepoke whakarewa pēhanga iti, ngā pokepoke whakarewa pēhi, me ētahi atu. Ko ngā pokepoke whakarewa tētahi o ngā taputapu tukanga nui. I roto i te hanga whakarewa, he nui te awe o tēnei ki te kounga o ngā whakarewa. He mea nui te whakapai ake i te hangarau whakarewa mō te whakapai ake i te kounga o ngā whakarewa, te whakawhanake i ngā whakarewa hou me te whakapai ake i te taumata o te tukatuka tata-kupenga. Mā te ahunga whakamua o te hangarau pokepoke whakarewa ka whakaratohia he whakarewa tika ake, he uaua ake, he kounga teitei ake mō te motuka, te hiko, te hanga kaipuke, te kawe tereina, te rererangi me ētahi atu ahumahi, ā, ka whakatairanga i te whakapai ake i te taumata whānui o te ahumahi hanga.

I te tere o te whanaketanga o ngā ahumahi pēnei i ngā motuka, ngā motopaika, me te rererangi, kei te piki haere ngā pokepoke whakarewa i te tere neke atu i te 25% ia tau. Kua tino ahu whakamua te hangarau pokepoke whakarewa, engari ko te poraka miihini konumohe nui e tohuhia ana e ngā motuka me ngā pokepoke whakarewa mate matatini e whakawhirinaki ana ki ngā kawemai. Kua uru te umanga motuka me te motopaika o tōku whenua ki tētahi wā tipu tere, ā, kua piki ake te putanga mō ngā tau maha karapīpiti. Ka taea te matapae i roto i ngā tau 10 ki te 20 e whai ake nei, ka haere tonu te whakaputa pokepoke whakarewa o tōku whenua ki te whiwhi i te pana kaha me te tipu tere mai i te umanga motuka. I roto i te horopaki o te tiaki pūngao me te whakaiti i ngā tukunga, ka puhoi te tipu o ngā pokepoke whakarewa taumaha konganuku ferrous, i te mea ka piki ake te nui o ngā pokepoke whakarewa mate konumohe-konupora, ngā pokepoke whakarewa pēhanga iti me ngā pokepoke whakarewa pēhi.
