I ngā tau tata nei, kua kite te umanga hanga i tētahi panonitanga nui i roto i te whakahaere matihiko o ngā ara me te whakamahinga o ngā tātari raraunga nui hei whakapai ake i te whai huatanga me te tiaki matapae. Ko tēnei auahatanga hangarau e akiakihia ana e te pikinga o te hiahia mō ngā otinga whai hua me te utu-whai hua i roto i ngā rāngai keri me te hanga. Ko tētahi o ngā wāhanga matua e tino pāngia ana e tēnei panonitanga matihiko ko te whakahaere i ngā ara keri, inā koa te whakamahi i tengā ara keri rapahei whakapai ake i te mahi me te roa o te ora.

Kua āta whakakapia ngā ara rino tuku iho e whakamahia ana i runga i ngā keri ki ngā ara keri rapa, he maha ngā painga e tukuna ana e ēnei ara, pērā i te whakaiti i te kino o te whenua, te pai ake o te kukume me te iti o te haruru. Heoi anō, mā te whakaurunga o te hangarau whakahaere matihiko ka pai ake te mahi me te roa o te ora o ngā ara keri rapa. Mā te whakamahi i ngā tono tātari raraunga nui, ka taea e ngā kamupene hanga te aroturuki i te āhua me te whakamahinga o ngā ara keri i te wā tūturu, ka taea ai te tiaki matatau ake me te whakaiti i te wā kore mahi.

Ka aro turuki tonu te hangarau whakahaere matihiko i ngā tawhā maha pērā i te taumahatanga o te ara, te kakahu me ngā āhuatanga whakahaere. Kātahi ka tukatukahia, ka tātarihia hoki ēnei raraunga wā-tūturu mā te whakamahi i ngā tono raraunga nui hei tautuhi i ngā tauira me ngā take pea. Mā te whakamahi i te mana o ngā raraunga nui, ka taea e ngā kamupene hanga te whiwhi māramatanga whai hua ki te mahi a te ara keri, ka taea ai e rātou te whakatau whai whakaaro mō ngā wā tiaki me ngā wā whakakapinga.

Hei tāpiritanga, ko te whakamahinga o ngā tātaritanga raraunga nui i roto iara keriMā te whakahaere ka taea te āwhina i te tiaki matapae, ka taea te tautuhi me te whakatau i ngā take pea i mua i te pikinga ake ki ngā whakatikatika utu nui, i te wā kore mahi rānei i whakaritea. Ehara i te mea ka whakapai ake tēnei huarahi matatau i te whai huatanga whānui o ngā mahi keri, engari ka āwhina hoki ki te penapena i ngā utu nui mō ngā kamupene hanga.

Ko te whakaurunga o te hangarau whakahaere matihiko me ngā tono tātari raraunga nui i roto i te ao keri he tauira mārama o te auahatanga hangarau e tutuki ana i te hiahia o te mākete. Kei te piki haere te whakamahinga o ngā otinga whakahaere ara matatau i te mea e rapu ana ngā kamupene hanga i ngā huarahi hei arotau i ngā mahi me te whakaiti i ngā utu whakahaere. Ko te kaha ki te aroturuki, te tātari me te arotau i te mahi ara keri i te wā tūturu e hangai ana ki te arotahi tipu haere o te umanga ki te whai huatanga me te pumau.

He maha ngā tono e whakaatu ana i ngā painga tūturu o te whakahaere matihiko ngokingoki me ngā tono tātari raraunga nui i roto i te umanga hanga. Hei tauira, i whakatinanahia e tētahi kamupene hanga e tohunga ana ki ngā kaupapa keri nui he pūnaha whakahaere ara matihiko mō āna waka keri kua rite ki ngā ara rapa. Mā te whakamahi i ngā tātari raraunga nui, i taea e te kamupene te tautuhi i ngā tauira whakamahinga me te arotau i te tiaki ara, ā, nā reira ka whakaitihia te wā kore mahi e pā ana ki te ara mā te 20% me te whakapai ake i te whai huatanga o te mahi whānui mā te 15%.

I roto i te poto, kua tino hurihia e te whakahaere mamati o ngā ara me te whakamahinga o te tātari raraunga nui ngā tikanga aroturuki me te tiaki ongā ara kerii roto i te umanga hanga. Ehara i te mea ka aro noa tēnei auahatanga hangarau ki te tono a te mākete mō ngā otinga whai hua ake, pumau ake hoki, engari ka puta hoki ngā painga tūturu e pā ana ki te whakapiki ake i te whai huatanga me te tiaki matapae. I te mea kei te awhi tonu ngā kamupene hanga i te panonitanga matihiko, ka whai wāhi nui te whakaurunga o ngā otinga whakahaere ara matatau ki te hanga i te heke mai o ngā mahi keri.
