Ko te mīhini waka e pā ana ki te tukanga hangarau o te tukatuka me te hanga i te miihini waka, te pūnaha tuku, te anga me ētahi atu wāhanga. He hangarau tino nui te hangarau mīhini waka i roto i te umanga waka hou, ā, ko tōna kounga me te tika e pā tika ana ki te mahi me te haumaru o ngā waka. He maha ngā hononga o te mīhini waka, tae atu ki te whakarewa, te hanga, te tā, te whakarewa, te pepa whakarewa, te tapahi, te whakamahana, te whakamahana mata, me ētahi atu.

Ko te tapahi tētahi o ngā hangarau matua o te miihini waka. Ko tana mahi matua ko te tango i ngā rauemi taikaha i runga i te mea mahi mā te tapahi kia whiwhi ai i te āhua me te rahi e hiahiatia ana. Ko ngā tukanga tapahi miihini waka e whakamahia whānuitia ana ko te huri, te poka, te mira, te keri me ētahi atu. I roto i ēnei, ko te huri te tikanga tukatuka e whakamahia whānuitia ana. Ka hurihia te mea mahi me te taputapu kia tapahia te taputapu i te mata o te mea mahi kia whiwhi ai i te āhua me te rahi e hiahiatia ana. Ka tutuki te poka mā te huri i te taputapu me te mea mahi kia tapahia e te taputapu i te mata o roto o te mea mahi kia whiwhi ai i te āhua me te rahi o roto e hiahiatia ana. Ko te mira mā te huri i te taputapu me te mea mahi kia tapahia e te taputapu i te mata o te mea mahi kia whiwhi ai i te āhua e hiahiatia ana o te papa me te mata. Ko te keri he huri i te mata o te keri me te mea mahi kia tapahia e te mata o te mea mahi kia whiwhi ai i te āhua me te rahi e hiahiatia ana o te kōhao.

Haunga te tapahi, kei roto hoki i te miihini waka te maimoatanga wera me te maimoatanga mata. Ko te maimoatanga wera e pā ana ki te whakarerekē i te hanganga me ngā āhuatanga o ngā rauemi whakarewa mā te whakamahana me te whakamatao, kia pai ake ai te pakeke, te kaha me ētahi atu āhuatanga. Ko ngā tikanga maimoatanga wera e whakamahia whānuitia ana ko te tinei, te whakamahana, te whakataurite, me te whakamahana. Ko te maimoatanga mata e pā ana ki tētahi raupapa maimoatanga i runga i te mata o te mea mahi kia ātete ai ki te kakahu, ki te waikura, ki te ataahua me te whakapaipai. Ko ngā tikanga maimoatanga mata e whakamahia whānuitia ana ko te whakakikorua hiko, te rehu, te pupuhi onepu, te whakakanapa, me ētahi atu.

He mea tino nui te mahi a te hangarau miihini motuka i roto i te umanga motuka o ēnei rā. I te whanaketanga o te umanga motuka, kei te auaha tonu, kei te whakapai ake hoki te hangarau miihini motuka, e tino whakapai ake ana i te mahi, te haumaru me te whakamarie o ngā motuka. I ngā rā kei te heke mai, me te puta tonu mai o ngā waka hou pēnei i ngā waka hiko hou me ngā waka atamai, ka haere tonu te whanaketanga me te whakapai ake o te hangarau miihini motuka, ka whakarato i te tautoko hangarau pakari ake mō te whanaketanga o te umanga motuka.
