whakaahuatanga
Ko te kerēne whakarewa, he mīhini hiki kaha, he maha hoki ngā whakamahinga, kua waiho hei taputapu tino nui i roto i te umanga hanga. Ko tōna kaupapa matua he āwhina i te hanga me tete tāutanga o ngā piriti, ngā ara piki maunga, me ngā huarahi teitei. He mahi nui tā tēnei kerēni ki te hiki haumaru i ngā wāhanga hanganga taumaha, pērā i ngā pou raima kua oti te hanga, me te whakanoho tika i aua wāhanga ki ō rātou tūranga kua tohua.
Nā, me ruku tātou ki ngā āhuatanga hanganga e tino kitea ai te kerēne whakarewanga i roto i te ao hanga. Kei te pūtake o tēnei kerēne he anga pakari e whakarato ana i te pumau me te tautoko i te wā e hiki ana. Ko te tikanga he mea hanga tēnei anga ki te maitai kounga teitei, kia tino kaha ai, kia roa ai te mau. Kei roto ko ngā pou poutū, ngā pou whakapae, me ngā tautoko whakarara, he mea hanga katoa kia tū atu ki ngā kawenga taumaha, kia mau tonu ai te pumau i raro i ngā āhuatanga kino.
Ko tētahi o ngā āhuatanga rongonui o te kerēne whakarewa ko ōna ara whakarerekētanga. Kei ngā taha e rua o te kerēne ēnei ara, ā, ka taea te neke ngāwari i te papa hanga. Mā te kaha ki te toro atu, ki te hoki whakamuri rānei, ka taea e te kerēne te urutau ki ngā whānuitanga piriti rerekē, kia pai ai te tūnga i te wā e hiki ana. He mea tino nui tēnei whakarerekētanga ina whakahaerehia ana ngā kaupapa hanga uaua me ngā āhua rerekē.
Hei tautoko i te mahi hiki, ka whakamahia e te kerēni ētahi tikanga hiki. Ko te tikanga hiki matua he pūnaha tītaha waipēhi, e whakarato ana i te kaha e hiahiatia ana hei hiki i ngā wāhanga taumaha kua oti te hanga. Ka whakanohoia ēnei tītaha ki te taha o te taura matua, kia taea ai te tohatoha kawenga ōrite i te wā e hiki ana. Hei tāpiri, kua rite te kerēni ki ngā tikanga āwhina pērā i ngā pou me ngā whakaū, e whakarei ake ana i te pumau me te whakaiti i te nekeneke, te piko rānei ka puta i te wā e hiki ana.
He mea tino nui te haumaru i roto i ngā kaupapa hanga katoa, ā, kāore te kerēne whakarewa i te rerekē. Nō reira, he maha ngā āhuatanga haumaru kua rite ki a ia. Kei roto i ēnei ko ngā pana here, ngā pātene aukati ohorere, me ngā pūnaha tiaki taumaha. Mā ēnei mahi ka whakarite kia mahi te kerēne i roto i tōna kaha kua tohua, ā, ka ārai i ngā aituā, i ngā kino rānei nā te taumaha rawa. Heoi anō, kua hangaia te kerēne me ngā taputapu ārai-hurihuri me ngā pūoko tere hau hei whakahaere i ngā āhuatanga huarere kino, hei whakarite anō i te haumaru o ngā kaimahi me te papa hanga.
