Tetakirere kuahahe takirere whānui noa iho, he whānuitia hoki ōna whakamahinga. E whakamahia ana i roto i te tiaki wai, te whakarewa me ētahi atu ahumahi. Kua mōhiotia whānuitia tōna whakamahinga.zi hangaia e te mākete. I roto i ngā tau maha o te tirotiro me te whakamātautau kounga me te hangarau, ehara i te mea ko te kaituhi anake i mahi i ētahi rangahau mō te kimi i te takirere kuaha, engari ko te whakamahinga hoki o te takirere kuaha, kua nui ake taku rangahau me te tino tupato.
Kei raro nei he kōrero whānui mō te hanganga, te whakamahinga, te rapurongoā, te tirotiro kounga me ētahi atu āhuatanga o te takirere kēti.
He hanganga
Te hanganga o tetakirere kuahaTetakirere kuahahetakireree whakamahi ana i te pereti kuaha me te nohoanga takirere hei whakahaere i te whakatuwheratanga me te katinga. Ko tetakirere kuahako te nuinga o te mea he tinana takirere, he nohoanga takirere, he pereti kuaha, he kakau takirere, he taupoki takirere, he reta tākai, he taupoki pēhanga tākai, he nati kakau takirere, he ringaringa-wira, me ētahi atu. I runga i te panonitanga o te tūranga whanaunga i waenga i te kuaha me te nohoanga takirere, ka taea te whakarerekē i te rahi o te awaawa, ā, ka taea hoki te tapahi i te awaawa. Hei kati pūmau i te takirere kuaha, ka hurihia te pereti kuaha me te nohoanga takirere.
E ai ki te āhua rerekē o te hanganga o te takirere kuaha, ka taea te wehewehe i te takirere kuaha kia rua ngā wāhanga: he poro me te whakarara.
He āhua rite te pereti kuaha o te takirere kuaha poro, ā, ko te mata hiri e anga ana ki te rārangi pokapū o te awaawa. Ko te poro i waenganui i te pereti kuaha me te nohoanga takirere hei hiri (kati). Ka taea te pereti poro hei kuaha kotahi, hei kuaha takirua rānei.
Ko te mata hiri o te takirere kuaha whakarara he whakarara tetahi ki tetahi, ā, he poutū ki te rārangi pokapū o te awaawa. E rua ngā momo: he tikanga tuwhera me te tikanga kore-tuwhera. He kuaha takirua me te tikanga tuwhera. Ina heke te kuaha, ka tautokohia e ngā poro o ngā kuaha whakarara e rua ngā kuaha e rua i runga i te nohoanga takirere i te pari, ka tapahia te awaawa rere. Ina piki te kuaha, ka tuwhera, ka wehea te koko me te kuaha me te kuaha, ka piki te kuaha ki tētahi teitei, ā, ka puritia te poro e te pereti kuaha takirua kāore he tikanga tuwhera. Ina paheke te pereti kuaha ki roto i te nohoanga takirere i runga i ngā mata nohoanga takirere whakarara e rua, ka whakamahia te pēhanga o te wai hei pēhi i te pereti kuaha ki runga i te tinana takirere i te taha putanga takirere hei hiri i te wai.
E ai ki ngā nekehanga rerekē o te kakau takirere ina whakatuwheratia, ina katihia hoki te kuaha, ka wehea te takirere kuaha kia rua ngā wāhanga: te takirere kuaha tuwhera me te takirere kuaha pōuri. Ina whakatuwheratia, ina katihia rānei te kakau takirere me te pereti kuaha o te takirere kuaha tuwhera, ka piki, ka heke i te wā kotahi; ina whakatuwheratia, ina katihia rānei te takirere kuaha pōuri, ka huri noa te kakau takirere, kāore e kitea te pikinga me te hekenga o te kakau takirere, ā, ka ara ake, ka heke rānei te pereti takirere. Ko te painga o te takirere kuaha tuwhera he taea te aromatawai i te teitei whakatuwheratanga o te awa mā te teitei e ara ake ana o te kakau takirere, engari ka taea te whakapoto i te teitei o te pupuri. Ina anga atu ki te ringa-wira, kakau rānei, hurihia te ringa-te wira, te kakau rānei e huri ana i te taha matau, ā, kua kati te takirere.
