Tātaritanga take e pā ana
Tauira tono i roto i te pūnaha kawe: I roto i te pūnaha kawe taonga, ka whakamahia te mekameka roera 12A hei taraiwa i te whitiki kawe. Nā te mea he maha ngā niho pīkau o te pūnaha kawe, ā, he tawhiti nui ki waenganui, me roa ake te mekameka hei whakarite i te pumau me te pono o te tuku. Mā te tatau me te whakatikatika tika, ka whakatauhia te roa o te mekameka e tika ana, ā, ka tāutahia he taputapu whakapūmau hei utu mō te roa o te mekameka. I roto i te mahi tūturu, he pai te mahi tuku o te mekameka, he pumau te mahi a te pūnaha kawe, ā, kāore he raruraru o te mekameka he tino wetekina, he tino piri rānei.
Ngā Tauira Whakamahinga i roto i ngā Mīhini Ahuwhenua: I roto i ngā mīhini ahuwhenua, ka whakamahia te mekameka roera 12A hei taraiwa i te taputapu hauhake. Nā te taiao mahi uaua o ngā mīhini ahuwhenua, ka pāngia ngāwari te mekameka e te puehu, te paru me ētahi atu poke, ka tere ake te pakaru. Nō reira, i te wā e whakatau ana i te roa o te mekameka, me te whakaaro ki ngā āhuatanga pēnei i te maha o ngā niho pīkau me te tawhiti pokapū, ka rāhuitia he nui o te tawhiti whakaroa. I taua wā anō, ka whakamahia ngā mekameka kounga teitei me ngā mahi tiaki auau pēnei i te horoi me te whakahinuhinu hei whakaiti i te pakaru me te whakaroa o te mekameka. I te whakamahinga tūturu, kua tino pai ake te roa o te mahi a te mekameka, ā, kua whakamanahia hoki te whai huatanga o te mahi a ngā taputapu.
