Ko tētahi o ngā mahi matua ongā puna hauKo te mahi a ngā matapihi tuanui he whakahaere i te whakatuwheratanga me te katinga o te matapihi. Mā te whakamahi i te kaha i hangaia e te hau kua pēhia, ka taea e ēnei pou te hiki me te whakaheke i te matapihi tuanui, kia maeneene ai te nekehanga, kia whakahaeretia ai hoki. Ehara i te mea ka pai ake te whakamahi engari ka ārai hoki i te pakaru ohorere, te taka rānei o te matapihi, ka whai wāhi ki te haumaru me te ngāwari o te whakahaere.
Haunga te whakahaere i te nekehanga,ngā puna hauHe tautoko nui hoki ēnei mō ngā matapihi tuanui. He taumaha, he uaua hoki te whakahaere i ngā matapihi tuanui, inā koa i roto i ngā hoahoa nunui ake, matatini ake rānei. Ka āwhina ngā puna hau ki te pikau i te taumaha o te matapihi, ka whakaiti i te kaha e hiahiatia ana hei whakatuwhera me te kati. Ehara i te mea ka ngāwari ake te whakamahi i te matapihi tuanui mā tēnei tautoko, engari ka roa ake hoki tōna roanga mahi mā te whakaiti i te pakaru me te haehae o ngā tikanga whakahaere.
Hei tāpiritanga, ka whai wāhi ngā puna hau ki te haumaru me te pumau o ngā matapihi matapihi. Ina tuwhera te matapihi, ka pupuri te turanga puna hau i te matapihi ki tōna tūranga, ka ārai i te katinga ohorere nā ngā āhuatanga o waho pēnei i te hau, i te hauhautanga rānei. Mā tēnei āhuatanga ka noho tonu te matapihi matapihi ki te tūranga e hiahiatia ana, ka whakarato i te rangimarie o te hinengaro ki ngā kaiwhakamahi, me te whakaiti i te tūponotanga o ngā aituā, ngā kino rānei.
Ko tētahi atu painga o ngā puna hau i roto i ngā matapihi tuanui ko tā rātou mahi hei whakarite ngāwari i te tūranga o te matapihi. Ahakoa e hiahia ana ngā kaiwhakamahi ki te whakatuwhera i te matapihi tuanui mō te hauhautanga, ki te whakarite rānei i te koki hei whakahaere i te urunga mai o te rā, ka taea e ngā puna hau te whakanoho maeneene me te tika. Mā tēnei ngāwari ka whakarei ake i te mahi a te matapihi tuanui, ka taea e ngā kaiwhakamahi te whakarite i tō rātou taiao o roto kia rite ki ō rātou hiahia.
Hei whakamutunga,ngā puna hauhe wāhanga nui o ngā matapihi tuanui, e tuku ana i te whānuitanga o ngā painga hei whakarei ake i tō rātou mahi, te haumaru, me te wheako kaiwhakamahi. Mā te whakarato i te nekehanga whakahaere, te tautoko, te pumau, me te whakarerekētanga, ka whai wāhi ngā puna hau ki te mahi whānui me te whai hua o ngā hoahoa matapihi tuanui hou.
