Tātaitai Tuanui

Ka rerekē ngā utu whakaurunga tuanui hou i Aotearoa e ai ki te rauemi me te uaua o te tuanui. Ko te tuanui kirihou raina-roa, ngongoro rānei — arā, te kōwhiringa noa o Aotearoa — ka utu tata ki te $80-150 ia mita tapawhā i whakauruhia. Ahakoa he iti ake te utu o ngā hua tuanui Colorsteel, ka noho tonu rātou ki te $100-160/m2, ā ko ngā tiaka raima ka piki ake ki te $100-180/m2 i whakauruhia. He kore-noa ngā paparanga whetū-pā i Aotearoa, kāore hoki e rite ana ki te rangi o konei. Mō tētahi whare toharite o Aotearoa me te 150-200m2 o te rohe tuanui, ka haere mai ngā utu whakataunu tuanui katoa i te $12,000 ki te $40,000, e ai ki te rauemi, te tauinitanga o te tuanui, te uaua, te tangohanga o te tuanui tawhito, me te poraka. Ko te 40-60% o te utu katoa ko ngā mahi-ā-ringa. Whakamahia tonu tētahi kaihanga tuanui raihana, ā tirohia ngā taranata hua. Puna: buildingperformance.govt.nz.

Hei tātai i te rohe tuanui, timata ki te rohe tapuwae papa-raro o te whare i roto i ngā mita tapawha, katahi ka whakamahi i tētahi āhuatanga tauinitanga e ai ki te koki tuanui. Mō tētahi tuanui iti-tauinitanga (tata ki te 15 ira), ko te āhuatanga tauinitanga ko te 1.04, nā reira ko tētahi tapuwae 150m2 ka homai i te rohe tuanui tata ki te 156m2. Mō tētahi tauinitanga waenga (30 ira), ko te āhuatanga ko te 1.15 noa, ka homai i te 172m2. Mō tētahi tuanui toi (45 ira), ko te āhuatanga ko te 1.41, ka homai i te 212m2. Tapirihia te rohe mō ngā aho-taha, ko te tikanga 300-600mm ia taha. Ko ngā tuanui uaua me ngā hip, ngahere, me ngā matapihi-tuanui e hiahia ana i te ine ine ake. Mō tētahi korero utu tika, ka ine tika te kaihanga tuanui i te rohe tuanui. Puna: buildingperformance.govt.nz.

I Aotearoa, ko te whakataunu tuanui rite-ki-rite (whakataunu i te rauemi rite ki te rauemi rite) kāore e hiahia ana i tētahi whakaaetanga hanga i raro i ngā whakauruatanga Rarangi 1 o te Ture Hanga 2004. Ko te tikanga ko te whakataunu konganuku tiata ki te konganuku tiata hou, tiaka ki ngā tiaka rite rānei, ka wehea taua. Heoi, ki te hurihia e koe te rauemi tuanui (hei tauira, mai i ngā tiaka ki te kirihou raina-roa), whakarereke i te hanganga tuanui, huri i te tauinitanga tuanui, me te tāpiri i ngā matapihi tuanui hou, ka hiahia tētahi whakaaetanga hanga. Me whai tonu ngā mahi ki te Waehere Hanga o Aotearoa ahakoa te āhua o te whakaaetanga. Tirohia tonu to kāwanatanga ā-rohe i mua i te haere, nā te mea ka rerekē ngā āhuatanga motuhake.

Ko te rauemi tuanui rongonui rawa atu o Aotearoa ko te tuanui kirihou raina-roa ngongoro, e rite ana ki te rangi o Aotearoa, ka whakamahia i te nuinga o ngā whare. Ko Colorsteel (he hua a NZ Steel me tētahi kaupeka tae i tunu-uru) te waitohu matua, e wātea ana i ngā āhua penei i a Corrugate, Trimdek, me Longrun. Ko Colorsteel Endura me Colorsteel Maxx ngā momo tino kounga me ngā taranata roa ake (ki te 30-50 tau i ngā taiao tiakina). Ka rongonui anō a Zincalume (āhua konganuku kau) he iti ake te utu. Ko ngā tiaka raima he noa i ngā whare i hangaia i ngā tau 1970-1990 a ka mahi tonu mō ngā mahi whakataunu. Ko ngā tiaka terracotta ka whakamahia i ētahi whare taonga me ngā whare tino kounga.
