Kei te aro nui haere ngā mahi keri ki te oranga tonutanga, ā, ko teYT29A hau keri tokae tautoko ana i taua whāinga. Ka whakaitihia e tana pūnaha hau whai hua te kawenga o te pūhiko, ka tapahia ngā mea e ruate whakapaunga wahie me ngā tukunga.

Mā te kaha pānga pai o te keri ka tere ake te uru, arā, he iti ake te wā me te kaha e pau ana mō ia poka. Nā te roa o ngā wā mahi me te roa o te mau, ka tukuna e te YT29A he ara pai mō te taiao ki ngā mahi keri hou, hua nui.

Kei raro te umanga keri o te ao i te pēhanga nui kia whakataurite i tana tūranga nui i roto i te ōhanga me tōna tapuwae taiao. I roto i tēnei horopaki, ehara i te mea ko te mana anake te kaupapa o te auahatanga taputapu engari ko te mahi atamai. Ko te YT29A he peke nui ki tēnei huarahi, e tautuhi ana i te whai huatanga o te keri hau. Mā te arotau i te whakamahinga o te hau, ka hangaia e te keri he pānga tauwhiro o ngā painga pumau. Ko te whakaiti i te kawenga kōpeketanga ka hua tika ki te whakaiti i te whakamahinga tīhiera mō ngā mahi i waho o te whatunga hiko, te whakaiti rānei i te kukume hiko i ngā wāhi hono whatunga hiko. Ka tapahia e tēnei ngā utu whakahaere, ā, ka tino whakaitihia ngā tukunga waro me ngā matūriki e pā ana ki ngā mahi keri.

Hei tāpiri atu ki tēnā, ko te aro nui o te hangarau o te YT29A ki te whai huatanga o te huringa ora. Nā te roa o te mau o te mahi me te roa o ngā wā mahi, he iti ake te whakakapinga me te iti ake o te tiaki. Mā tēnei ka whakaitihia te wā kore mahi o ngā taputapu, ka whakanui ake i te hua o te papaanga katoa, me te whakaiti anō hoki i te rerenga para o ngā wāhanga kua tawhito me ngā taonga pau. Ko te painga "iti ake te wā mō ia poka" he inenga nui; ko te tere o te keri ka taea e te mīhini kotahi te whakatutuki i te nui ake i roto i te huringa, ka whakaiti pea i te maha o ngā keri e hiahiatia ana i runga i te papaanga, ā, ka arotahi ake, ka whakaitihia hoki te tapuwae mahi.

E kite ana ngā kaitātari ahumahi i ngā taputapu pēnei i te YT29A hei mea nui mō te heke mai o te tango rauemi kawenga. "Ka tutuki te pumau pono i roto i te keri mā roto i ngā hua whakaemi," e ai ki tētahi pūrongo ahumahi tata nei. "Ina taea e tētahi taputapu pēnei i te keri toka te whakaiti i te whakamahinga wahie, te tapahi i ngā tukunga, me te whakarei ake i te hua i te wā kotahi, ka whakatakotohia he paerewa hou. E whakaatu ana ko te tiaki taiao me te hiranga whakahaere ehara i te mea motuhake tetahi ki tetahi, engari he whāinga mahi tahi." I te whakakaha haere o ngā ture me te whanake haere o ngā tumanakohanga a ngā kaipupuri hea, kei te tere te neke o te tango i aua hangarau whai hua-pūngao mai i te painga rautaki ki te mea nui ki te whakahaere.
