Ko te pūwhakamātao rokiroki makariri he momo pūwhakamātao e whakamahia ana i roto i te rokiroki makariri (ko te kupu ahumahi ko te "hau whakamatao"). Ko tana mahi he tuku i te hau whakamatao kua mākūkū, iti-pāmahana, e mahi ana hei takirere whānui wera, ki te whakawhiti wera ki te reo e whakamataohia ana, e whakamatao ana i te hau whakamatao kua mākūkū me te tango i te wera mai i te rokiroki makariri. E rima ngā wāhanga matua o te pūwhakamātao rokiroki makariri: ngā paipa whakawhiti wera whakamatao, he pā tuaka, he tohatoha, he taputapu whakarewa, me te paepae maturuturu. Ko te hau whakamatao wai pāmahana rūma teitei-pēhanga mai i te pūwhakamātao rokiroki makariri ka whakawhāitihia e te takirere whānui wera ka tomo tika ki te tohatoha o te pūwhakamātao kia tohatoha ōrite i mua i te tukuna ki ngā paipa whakawhiti wera hei whakamatao me te mimiti wera. Ka akiaki te pā tuaka o te pūwhakamātao i te hau kia rere i roto i te rokiroki makariri, kia tutuki ai te kaupapa o te whakamatao.
Ko te kaupapa whakamatao o te hau whakamatao mimiti penei: Ina rere te pā, ka hangaia he pēhanga kino i roto i te kōhao, ka akiaki i te hau o waho kia rere mā roto i te mata pūwero, makuku o te papa whakamatao mimiti. Ka akiakihia te pāmahana o te hau maroke e haere ana i roto i te papa kia heke ki te tata ki te pāmahana o te hau maku o te hau o waho. Ina koa, ko te pāmahana o te hau maroke i te putanga o te hau whakamatao he 5-12°C te iti iho i te pāmahana o te hau maroke o waho (tae atu ki te 15°C i ngā rohe wera, maroke). Ko te maroke me te wera o te hau, ko te nui ake o te rerekētanga pāmahana, ā, ko te pai ake o te pānga whakamatao. Nā te mea ka kumea tonu te hau mai i waho ki roto i te rūma (e kiia ana tēnei he pūnaha pēhanga pai), ka pupuri i te hau hou o roto. I te wā kotahi, nā tōna kaupapa whakamatao mimiti, e rua āna mahi hei whakamatao me te whakamakuku (ka taea e te makuku whanaunga te eke ki te 75%). I roto i ngā awheawhe kakahu me te whatu, ehara i te mea ka whakapai ake i ngā āhuatanga whakamatao me te whakamakuku engari ka purea hoki te hau, ka whakaiti i te whati miro i te wā o te mahi whatu, ā, ka whakapai ake i te kounga o ngā hua kakahu. Ko ngā whakamatao hau mimiti (e mōhiotia ana ko ngā ārai hau mākū) e karapotia ana e ngā ārai mākū āhua honikoma, he mea hanga ki ngā rauemi motuhake, e whakarato ana i tētahi mata whānui. Ka whakamakuku tonu ēnei ārai e tētahi pūnaha tohanga wai. I roto, ka hangaia e tētahi pā hau whai hua, iti te haruru, penapena hiko he pēhanga kino, ka panaia te hau o waho mā roto i ngā ārai makuku ki roto i te waeine. Ka mimiti te mimiti o te wai i runga i ngā ārai i te wera, ka whakamatao i te hau e haere ana. I te wā kotahi, ka whakanuia e te mimiti o te wai mai i ngā ārai te haumākū o te hau, ā, ka whakaratohia he mahi rua o te whakamatao me te whakamakuku.
Ngā Pouaka Whakamatao Hau Whakamomona Ahumahi Whakapiko
He mea whakamahi noa ngā whakamatao hau mimiti momo-maroke i roto i ngā ahumahi. Ka whakawhirinaki rātou ki te hau e rere ana i roto i ngā koiri mimiti i roto i te whakamatao hei whakamatao i te hau e rere ana i waho o ngā koiri. Ina tāutahia ki te papa i roto i te rūma rokiroki makariri, ka kiia he whakamatao hau mimiti tū-papa; ina tāutahia ki te tuanui, ka kiia he whakamatao hau mimiti e mau ana ki te tuanui.
Nā te mea kei raro iho i te 0℃ te pāmahana o te mata o te mīhini whakapūngao i roto i te wāhanga rokiroki makariri, ka puta he hukapapa ki te mata o waho o te pouaka whakamatao hau rokiroki makariri i te roanga o te wā whakamatao. Ehara i te mea ka pā kino tēnei hukapapa ki te tauwehenga whakawhiti wera o te pouaka whakamatao hau rokiroki makariri engari ka whakaiti nui hoki i te rahinga o te hau e rere ana. Ka pā kino tēnei ki te kaha whakawhiti wera o te pouaka whakamatao hau rokiroki makariri, ka heke nui te mahi a ngā taputapu rokiroki makariri. Hei whakarite i te mahi whakawhiti wera pai, he mea nui te whakarewa mō te pouaka whakamatao hau rokiroki makariri. I tēnei wā, ko te tikanga whakarewa tino noa mō ngā pouaka whakamatao hau rokiroki makariri ko te whakarewa hiko. He maha ngā painga o te whakarewa hiko, pērā i te whakarewa tino me te whakahaere aunoa, e rongonui ana i roto i te maha o ngā kaupapa rokiroki makariri iti, rongoā, me te rokiroki makariri huawhenua.
Ko ngā momo hanganga whakamatao hau ko te tū-papa, te pupuhi-runga-papa, te pupuhi-raro-papa, te pupuhi-pae-papa, te pupuhi-tuanui me ngā momo kōwae.
