Te hoahoa whānui o te takirere
Kei waho o te pokapū te kakau o te Takirere Pūrerehua Mahi Teitei i ngā papa e rua. Ko te rerekētanga tuatahi e ahu mai ana i te rārangi pokapū o te takirere, ā, ko te rerekētanga tuarua e ahu mai ana i te rārangi pokapū o te paipa. Mā tēnei ka wehea katoatia te kōpae mai i te kōpae i ngā nekehanga mahi torutoru noa iho mai i te nohoanga. Tirohia te whakaahua i raro nei:
Te hoahoa nohoanga
Mō te nohoanga, e ai ki te kōrero i mua ake nei, ka katihia te takirere rapa mā te pēhi ki roto i te ringaringa rapa. He hoahoa nohoanga Takirere Pūrerehua G Mahi Teitei. E whakaahua ana te ahua i raro nei i te pānga o te nohoanga i roto i ngā āhuatanga e 3:
I muri i te huihuinga: ina huihuia i raro i te kore pēhanga
Ina huihuia i raro i te kore pēhanga, ka whakakahangia te nohoanga e te pereti pūrerehua. Mā tēnei ka taea te hiri i te mirumiru mai i te taumata korehau ki te taumata pēhanga mōrahi o te takirere.
Pēhanga tuaka:
Ka hanga e te kōtaha nohoanga-G he hiri piri ake i te nekenga o te pereti. Ka whakaitihia e te hoahoa whakaurunga te nekehanga nui o te nohoanga.
Te pēhanga i te taha whakaurunga:
Ka hurihia te nohoanga e te pēhanga ki mua, ka whakanuia te kaha hiri. Ko te whakaurunga ki te wāhi piko kua hangaia kia taea ai te huri i te nohoanga. Koinei te ahunga whakairinga pai rawa atu.
He mahi mahara tō te nohoanga o te Pūrerehua Mahi Teitei. Ka hoki te nohoanga ki tōna āhua taketake i muri i te utaina. Ko te kaha o te nohoanga ki te whakaora ka tautuhia e ngā inenga o te whakarerekētanga tuturu o te nohoanga. Ko te iti o te whakarerekētanga tuturu ko te tikanga he pai ake te mahara o te rauemi - he iti ake te tūponotanga ki te whakarerekētanga tuturu ina pāngia he kawenga. Nō reira, ko te iti o ngā inenga whakarerekētanga tuturu ko te tikanga he pai ake te whakaora nohoanga me te roa o te roanga o te hiri. Ko te tikanga he pai ake te hiri i raro i te pēhanga me te huringa wera. Ka pāngia te whakarerekētanga e te pāmahana.
Te hoahoa tākai kakau me te peera
Ko te wāhi whakarite whakamutunga ko te hiri e ārai ana i te turuturu o waho mā te rohe kakau.
E kite ana koe i raro nei, he tino māmā noa iho te hiri o te kakau o ngā takirere rapa, kāore e taea te whakarite. E whakamahia ana e te hoahoa he pū rakau hei pokapū i te kakau me ngā kapu-U rapa e rua hei hiri i te wai kia kore ai e turuturu.
Kāore he whakatikatika e mahia ana ki te wāhi hiri, ko te tikanga mēnā ka puta he turuturu, me tango te takirere i te raina, ā, me whakatika, me whakakapi rānei. Kāore he tautoko kakau o te wāhi o raro o te rakau, nō reira, mēnā ka heke ngā matūriki ki te wāhi o runga, o raro rānei o te rakau, ka piki ake te taipana taraiwa, ka uaua ai te whakahaere.
Ko ngā Takirere Pūrerehua Mahi Teitei e whakaaturia ana i raro nei kua hangaia me te takai ka taea te whakarite (hiri porowhita) kia roa ai te ora mahi, kia kore ai hoki e turuturu. Mēnā ka puta he turuturu i roto i te wā, he repe takai ka taea te whakarite te takirere. Hurihia te mowhiti nati i ia wā kia mutu rā anō te turuturu.
✧ Ngā Painga o te Takirere Pūrerehua Mahi Teitei
I te wā e whakatuwheratia ana, e kati ana hoki te takirere porowhita maitai hanga, nā te mea he iti ake te waku i waenga i te kōpae me te mata hiri o te tinana takirere i tērā o te takirere kuaha, ka ātete ki te kakahu.
He poto noa te whiu whakatuwheratanga, te whiu kati rānei o te kakau takirere, ā, he tino pono te mahi tapahi, ā, nā te mea he rite te huringa o te putanga nohoanga takirere ki te whiu o te kōpae takirere, he tino pai mō te whakatikatika i te tere rere. Nō reira, he tino pai tēnei momo takirere mō te tapahi, te whakahaere rānei me te whakawhāiti.
