Ko te hanga whakarewa he tukanga hanga e hanga ana i te konganuku mā roto i ngā kaha pēhi, e whakaputa ana i ngā wāhanga he tino kaha, he tino pakari hoki. Nā te mea he maha ngā whakamahinga o ngā hanga whakarewa i roto i ngā tono nui pēnei i te rererangi, te motuka, te hinu me te hau, me te whakaputa hiko, he mea nui te whakarite i tōna kounga. Mā te tukanga tirotiro whai hua ka āwhina i te manatoko kei te tutuki ngā hua hanga whakarewa i ngā whakaritenga hoahoa, ngā whakaritenga āhuatanga miihini, me ngā paerewa ahumahi. E whakamārama ana tēnei tuhinga i te tukanga tirotiro taipitopito mō ngā hua hanga whakarewa, e kapi ana i ia wāhanga mai i te kōwhiringa rauemi mata ki te tuku whakamutunga.
Te Hiranga o te Tirotiro i roto i te Hanga
Mā te tirotiro hanga ka whakarite kia mahi te hua kia rite ki te mea i whakaritea i raro i ngā tikanga whakahaere. Ka taea e ngā hapa o ngā wāhanga hanga te arahi ki ngā pakaru wawe, te wā kore mahi, tae atu ki ngā aituā kino. Ko te tukanga tirotiro:
-
Whakaū i te tika o ngā āhuatanga
-
Manatoko i ngā āhuatanga matū me ngā āhuatanga ā-pūkaha
-
Ka kitea ngā hapa o te mata me roto
-
Ka whakarite kia tutukihia ngā paerewa a te kiritaki me te ahumahi
I roto i ngā ahumahi pēnei i te rererangi me te pūngao karihi, ehara te tirotiro i te mea he mehua whakahaere kounga anake engari he whakaritenga ture anō hoki.
Ngā Wāhanga o te Tukanga Tirotiro Hanga
1. Tirotiro Rauemi Mata
Ka tīmata te tukanga mā te manatoko i te kounga o te rauemi mata i mua i te tīmatanga o te hanga. Kei roto i tēnei ko:
