Te mimiti ru o te motuka
I roto i te pūnaha whakatārewatanga, ka wiri te wāhanga rapa i te pānga. Hei whakapai ake i te whakamarie o te waka, ka tāutahia te ngongo ru i te taha o te wāhanga rapa i roto i te whakatārewatanga. Hei whakaiti i te wiri, ko te ngongo ru e whakamahia ana i roto i te pūnaha whakatārewatanga waka he ngongo ru waipēhi te nuinga. Ko tōna mātāpono mahi, ina puta te wiri i waenga i te anga (te tinana rānei) me te toki, ka neke te piston i roto i te ngongo ru ki runga, ki raro. Ka rere te hinu i roto i te kōhao ngongo ru mai i tētahi kōhao mā roto i ngā pūwero rerekē ki tētahi atu kōhao.
I tēnei wā, ko te waku i waenganui i te pakitara o te kōhao me te hinu [1] me te waku ā-roto i waenganui i ngā ngota hinu ka hanga he kaha whakaiti i te wiri, kia puta ai te kaha wiri o te waka hei kaha wera hinu, ka mimitihia, ka tukuna ki te āhuarangi e te mea mimiti wiri. Ina noho tonu te wāhanga o te awa hinu me ētahi atu āhuatanga, ka piki ake, ka heke rānei te kaha whakaiti me te tere nekehanga whanaunga i waenganui i te anga me te toki (te wira rānei), ā, e pā ana ki te matotoru o te hinu.
Ko te mea e whakaitihia ana te pānga me te wiri e te ngongo ru me te wāhanga whakapūmau. Mēnā he nui rawa te kaha whakamākū, ka heke te ngāwari o te whakatārewatanga, ā, ka pakaru anō hoki ngā wāhanga hono o te ngongo ru. Nā te taupatupatu i waenganui i te wāhanga whakapūmau me te ngongo ru.
(1) I te wā e pēhia ana te whiu (e tata ana te toki me te anga tetahi ki tetahi), he iti te kaha whakamātao o te mea mimiti ru, kia tino whai hua ai te pānga o te wāhanga whakamātao me te whakaiti i te pānga. I tēnei wā, he mahi nui tā te wāhanga whakamātao.
(2) I te wā e toronga ana te whakatārewatanga (kei tawhiti te toki me te anga tetahi i tetahi), me nui te kaha whakamākū o te ngongo ru, ā, me tere te mimiti i te wiri.
(3) Ina nui rawa te tere i waenga i te toki (te wira rānei) me te toki, me whakanui aunoa te aukati i te rere o te wai kia mau tonu te kaha aukati i roto i tētahi rohe, kia kore ai e nui rawa te kawenga pānga.
He whānuitia te whakamahinga o te ngongo ru porotaka i roto i te pūnaha whakatārewatanga motuka, ā, ka taea e ia te mahi hei ngongo ru i roto i te whiu pēhanga me te whiu toronga. Ka kiia ko te ngongo ru rua-ara. Kei reira anō ngā ngongo ru hou, tae atu ki te ngongo ru pupuhi me te ngongo ru ātete ka taea te whakarite.
