I ngā tau tata nei, kua whakaarohia e ngā whenua maha o te ao, inā koa ko ngā whenua ahumahi kua whanake, te whanaketanga o ngā hua matū pai hei rautaki whanaketanga matua mō te whakapai ake i te hanganga me te whakatikatika i ngā ahumahi matū tuku iho, ā, kua whanake ā rātou ahumahi matū ki te huarahi "whakarei" me te "whakapaipai". I te whanaketanga tonu o te ōhanga pāpori, ka piki ake te hiahia o te tangata mō ngā hikohiko, ngā motuka, te ahumahi mīhini, ngā rauemi hanga hou, te pūngao hou me ngā rauemi tiaki taiao hou. Ngā matū hikohiko me ngā matū mōhiohio, ngā matū miihini mata, ngā matū rongoā, me ētahi atu. I te whanaketanga tonu, ka tere tonu te tipu o te mākete matū pai o te ao i te ahumahi matū tuku iho.
*Ngā matū pai
Ko ngā matū pai e pā ana ki ngā matū he nui te matotoru hangarau, he nui te uara tāpiri me te parakore e taea ai te whakarei ake, te whakawhiwhi rānei i tētahi hua (momo) ki ngā mahi motuhake, ki ngā mahi motuhake rānei i roto i te hanga me te tono puranga iti, ā, he matū taketake anō hoki. Ko te hua o te tukatuka hohonu.
I te tau 1986, i wehea e te Manatū Ahumahi Matū o mua ngā hua matū pai ki ngā wāhanga 11: (1) ngā patu pepeke; (2) ngā tae; (3) ngā paninga (tae atu ki ngā peita me ngā waituhi); (4) ngā tae; (5) ngā matū tauhohenga me ngā matū parakore teitei (6) ngā matū mōhiohio (tae atu ki ngā rauemi whakaahua-ā-ahua, ngā rauemi aukume me ētahi atu matū ka taea te whiwhi ngaru hikohiko); (7) ngā tāpiringa kai me te whāngai kararehe; (8) ngā piripiri; (9) ngā kaiwhakaoho me ngā momo tāpiringa; (10) ngā matū (ngā rauemi mata) me ngā matū o ia rā (i hangaia e te pūnaha matū); (11) ngā rauemi pūmua mahi i roto i ngā pūmua pūmua (tae atu ki ngā kiriata mahi, ngā rauemi whakapūmau, me ētahi atu). I te whanaketanga o te ōhanga ā-motu, ka haere tonu te whanaketanga me te whakamahinga o ngā matū pai ki te whānui, ā, ka haere tonu te piki haere o ngā wāhanga hou.
Ko ngā āhuatanga o ngā matū pai:
(1) He whānuitanga o ngā hua me te whānuitanga o ngā whakamahinga
E 40-50 ngā momo matū pai puta noa i te ao, neke atu i te 100,000 ngā momo. E whakamahia ana ngā matū pai i roto i ngā āhuatanga katoa o te oranga o ia rā, pērā i te rongoā, ngā tae, ngā patupatu pepeke, ngā paninga, ngā taonga matū o ia rā, ngā rauemi hiko, ngā matū pepa, ngā waituhi, ngā tāpiringa kai, ngā tāpiringa whāngai, te maimoatanga wai, me ētahi atu, tae atu ki te rererangi, te hangarau koiora, te hangarau mōhiohio, ngā rauemi hou, te hangarau pūngao hou, te tiaki taiao me ētahi atu tono hangarau teitei e whakamahia whānuitia ana.
(2) Hangarau whakaputa matatini
He maha ngā momo matū pai, ā, ka taea te whakawhānui i te hua takawaenga kotahi ki ētahi, ki ngā tekau rānei o ngā matū whakaputa mō ngā kaupapa rerekē mā roto i ngā tukanga rerekē. He uaua, he rerekē hoki te tukanga whakaputa, ā, he uaua hoki te hangarau. Me whakawhanake taiwhanga, whakamātautau iti, whakamātautau whakamātautau, kātahi ka whakaputa nui ngā momo matū pai katoa. Me whakahou, me whakapai ake rānei i roto i te wā e ai ki ngā huringa o ngā hiahia o ngā kaihoko o muri mai. He teitei ngā whakaritenga mō te pumau o te kounga o te hua, ā, me whakaputa tonu te kamupene i te tukanga me te kohikohi wheako i roto i te tukanga. Nō reira, ko te whakawhanaketanga o ngā matū whakaputa i roto i ngā wāhanga iti, te kohikohi wheako i roto i ngā tukanga whakaputa me te kaha ki te auaha ko ngā kaupapa matua o te whakataetae o tētahi umanga matū pai.
(3) Te uara tāpiri teitei o ngā hua
He roa te tukanga whakaputa e pā ana ki ngā hua matū pai, ā, he maha ngā mahi e hiahiatia ana. He uaua te tukanga hanga. Ka tutuki i te tukanga whakaputa ngā tikanga tauhohenga ngāwari, te taiao whakahaere haumaru, me ngā tauhohenga matū motuhake kia tutuki ai te wehenga matū. Me whai hangarau tukanga taumata teitei me ngā taputapu tauhohenga te ngāwari o te wehenga me te nui o te hua. Nō reira, he nui ake te uara tāpiri o ngā hua matū pai.
(4) Ngā momo hua matū
I roto i ngā mahi whaihua, ko ngā matū pai te āhua o ngā mahi whānui o ngā hua. Me tirotirohia ngā hanganga matū rerekē i roto i te hanganga matū, me te whakamahi katoa i te mahi tahi a ngā matū pai me ētahi atu matū i roto i te hanga i ngā momo horopeta. He maha ngā tono mō ngā hua matū pai i roto i te hanga ahumahi, ā, he uaua ki te whakatutuki i ngā hiahia o te hanga, o te whakamahinga rānei o tētahi hua kotahi. Hei tauira, ko te umanga maimoatanga wai kei reira te kamupene. Ko ngā matū motuhake e whakamahia ana i roto i tēnei mara ko ngā patu harore me ngā patu rimurimu, ngā kaihoko unahi, ngā aukati waikura, ngā kaiwhakarewa waikura, me ētahi atu, ā, ka taea te whakakotahi i ngā kaihoko matū mō ia kaupapa mā te whakamahi i ētahi kaihoko matū.
(5) He matotoru te hua ki ngā kaihoko o te hekenga
Ko ngā hua matū pai e whakamahia whānuitia ana i roto i ngā wāhanga motuhake o te tukanga whakaputa ahumahi, i te whakatutuki rānei i ngā mahi motuhake o ngā hua o muri mai. Nō reira, he nui ake ngā whakaritenga a ngā kaiwhakamahi mō te kounga me te pumau o te hua, ā, he tino pakari ake te tukanga whiriwhiri me ngā paerewa a te kaiwhakarato. Kia uru atu ki te rārangi kaiwhakarato, e kore e ngāwari te whakakapi.
