Mō ngā kaupapa hanga, he mea nui te whai taputapu tika kia oti pai ai te mahi. He mea noa ngā keri i ngā papa hanga, ā, he mea nui te mahi a ngā ara e whakamahia ana e rātou. I ngā tau tata nei,ara keri rapakua piki haere te rongonui nā te maha o ngā painga ki ngā ara maitai tuku iho.

Ko tētahi o ngā painga matua o ngā ara keri rapa ko tōna kaha ki te whakaiti i te kino o te whenua. Ka taea e ngā reera tuku iho te whakararu nui i te whenua, inā koa ngā mata tairongo pērā i te tarutaru, te uku, te raima rānei. I tētahi atu taha, ka tohatohahia e ngā ara rapa te taumaha o te keri kia ōrite ake, ka whakaitihia te pānga ki te whenua, ka whakaitihia hoki te mōrearea o te kino. Nā tēnei ka pai ngā ara rapa mō ngā kaupapa hanga e hiahia ana kia hangaia ki runga i ngā mata pakarukaru, ki ngā tāone nui rānei e matua ana te tiaki whenua.

Haunga tōna āhua pai ki te whenua,ngā ara kerika pai ake te mau me te pumau. Ka pai ake te mau o te rapa ki ngā momo whenua, tae atu ki te paru, te kirikiri, me ngā mata koretake. Mā tēnei mau kaha ake ka taea e te keri te nekeneke pai ake ahakoa i roto i ngā āhuatanga uaua, ā, ka piki ake te hua me te whakaiti i te tūponotanga o te paheke, te mau rānei.

Hei tāpiritanga, he maeneene ake, he mārie ake te oma o ngā ara rapa i ngā ara maitai. Mā te ngāwari o ngā ara rapa ka mimiti i te ru me te wiri, ka whakaiti i ngā taumata haruru, ā, ka whakarato i tētahi taiao mahi whakamarie ake mō ngā kaiwhakahaere me ngā kaimahi tata. He tino whai hua tēnei mō ngā kaupapa hanga i ngā wāhi noho, i ngā taiao tairongo haruru rānei.

Ko tētahi atu painga nui o ngā ara keri rapa ko tōna maha o ngā whakamahinga. He pai mō ngā momo mahi maha, mai i te whakapaipai whenua me te whakahoro ki te hanga rori me ngā mahi ratonga. Nā te kaha ki te urutau ki ngā whenua me ngā mata rerekē, he taonga nui ēnei mō ngā kaimahi kirimana me ngā kamupene hanga e hiahia ana ki te whakanui ake i ngā kaha o ā rātou keri i runga i ngā kaupapa maha.

Hei tāpiritanga, he iti ake ngā whakaritenga tiaki mō ngā ara rapa i ngā ara maitai. He ātete ki te waikura, ā, he maha ngā wā kei roto i ō rātou hoahoa ngā āhuatanga horoi-ake hei āwhina i te aukati i te kohikohinga o ngā paru. Mā tēnei ka whakaitihia te wā kore mahi me ngā utu tiaki, ā, ka āwhina i te whakapiki ake i te pai o te mahi me te whai hua o te utu.

Hei whakarāpopototanga, ko te whakamahinga oara rapa kerikua nui ngā painga kua kawea mai ki ngā kaupapa hanga. Nā te pai o te whenua, te pai ake o te kukume, te iti o te haruru, te whānui o te whakamahinga me te iti o ngā whakaritenga tiaki, he mea nui tēnei hei haumitanga mā ngā kaimahi kirimana me ngā kamupene hanga. I te mea kei te aro tonu te umanga hanga ki te pumau me te whai hua, tera pea ka nui haere te whakamahinga o ngā ara rapa, ka whai wāhi ki tētahi huarahi pai ake ki te taiao me te whai hua ki ngā kaupapa hanga.
