He tino kino ngā āhuatanga mahi o ngā keri, ngā puruta, ngā kereini ngokingoki me ētahi atu taputapu o ngā mīhini hanga, inā koa tengā ngokingokiI roto i te pūnaha hikoi i te mahi me tu atu ki te kaha ake o te taumahatanga me te pānga. Hei whakatutuki i ngā āhuatanga miihini o te ngokingoki, me mahi te tukatuka wera tae atu ki te maimoatanga wera, te hanga, te whakarewa me ētahi atu tukanga ki ngā wāhanga maha e hanga ana i te ngokingoki. Ko ngā tukanga tukatuka wera kua whakahuatia ake nei he tikanga tukatuka e whakamahi ana i te kaha. Nō reira, ko te whakamahi i te kaha hou, te hangarau hou, me te hangarau kua arotauhia kua noho hei huarahi nui ki te whakapai tonu i te mahi hua me te whakaiti i ngā utu hanga, me te whakapai tonu i te roa o te ratonga hua. Ka noho hei huarahi whai hua ki te penapena kaha.
