Ko te nui o ngā pākahiko i roto i te pūnaha rokiroki pūngao, te nui o te kaha me te mana, te whakatakotoranga matotoru o ngā pākahiko, me ngā āhuatanga mahi uaua me te rerekē, he ngāwari ki te pāngia e ngā raruraru pēnei i te tohatoha pāmahana kore taurite me te rerekētanga pāmahana nui i waenga i ngā pākahiko, ka arahi ki te hekenga o te mahi a te pākahiko, te whakahekenga o te kaha me te poto o te ora ratonga, ka pā ki te mahi a te pūnaha katoa, ā, i ngā take nui, ka arahi pea ki te rere wera me ngā aituā haumaru. Hei whakatutuki i te rokiroki pūngao ki te huringa nui, waenga-roa, te manawanui kaha me te ahunga mahi haumaru teitei, kua noho te hangarau whakamatao wai hei huarahi rongonui i roto i te mara o te whakahaere wera o te rokiroki pūngao.
I tēnei wā, kei te mākete ngā tikanga whakahaere wera matua, e whakaatuhia ana i raro nei.
Whakamatao hau
Ko te whakamatao hau he momo tikanga whakamatao e whakamahi ana i te hau hei reo matao me te whakawhiti wera whakawhiti hei whakaiti i te pāmahana o te pākahiko, e whakamahia whānuitia ana i roto i te pouaka whakamātao ahumahi, te teihana turanga whakawhitiwhiti kōrero me ngā whakahaere pāmahana pokapū raraunga, me te pakari hangarau me te pono teitei.
Whakamatao wai
Ko te whakamatao wai he momo wai hei whakamatao, e whakamahi ana i te rere o te wai hei whakawhiti i te wera i hangaia e ngā wāhanga o roto o ngā taputapu IT i roto i te pokapū raraunga ki waho o te taputapu. Ki te whakatauritea ki te whakamatao hau, he uaua ake, he kiato ake te hanganga o te pūnaha whakamatao wai, ā, kāore e hiahiatia he wāhi nui o ngā hongere whakamarara wera, nō reira he iti noa te wāhi e nohoia ana.
Whakamatao paipa wera
Ko te whakamatao o ngā paipa wera e whakawhirinaki ana ki te huringa āhua o te reo whakamatao kei roto i te ngongo hei whakatutuki i te whakawhiti wera, me te whai huatanga nui o te tohatoha wera, te haumaru me te pono, engari he nui hoki te utu, ā, he iti noa te tono mahi i roto i ngā pūnaha pākahiko nui-kaha pēnei i te rokiroki pūngao.
