Kei te anga atu te ao hou ki ngā wero uaua haere i te wā o te Wera Nui, i te mea ka whakanuia e te huringa āhuarangi ngā tauira wā rā tuku iho, me te hanga i ngā ngoikoretanga hou puta noa i ngā pūnaha tāone, ahuwhenua, me te pūngao e hono tahi ana. Kua tino whakarerekētia te āhua taketake o tēnei wā hītori e te mahana ā-tangata, me te tātaritanga pāmahana e whakaatu ana ko te toharite o te Wera Nui ināianei he 1.5-2.0°C te mahana ake i te ao i ngā wā o mua i te ahumahi i roto i ngā tataunga wā rā tuku iho. Ka pāngia ngā taiao tāone e ngā whakaaturanga tino kaha o te Wera Nui o nāianei, i reira ka hangaia e ngā mata raima me te uku ngā moutere wera pumau e rēhita ana ki te 7-10°C i runga ake i ngā rohe tuawhenua e karapoti ana i ngā wā whakaora i te pō. Ka pāngia ngā hanganga hiko e te taumahatanga nui i tēnei wā rā, i te mea ka hangaia e te tono whakamatao ngā kawenga tihi e whakawehi ana i te pumau o te whatunga me te whakaatu i ngā rerekētanga ōhanga-pāpori i roto i te urunga ki te whakahaere āhuarangi. Ka pāngia ngā pūnaha hauora tūmatanui e ngā wero nui haere i ngā huihuinga Wera Nui o nāianei, i reira ka hono ngā mate e pā ana ki te wera tuku iho me ngā raruraru manawa mai i te parahanga hau kua kaha ake me ngā tauira mate pangia kua whakarerekētia e ngā nohoanga kawe whānui. Ka ngoikore ngā whatunga kawe waka i ngā whakaaturanga tino nui o tēnei wā rā, me ngā pūnaha tereina e pāngia ana e te piko o te ara, ngā rori e whakawhanake ana i ngā hapa hanganga, me te rererangi e anga atu ana ki te whakaiti i te kaha hiki i ngā hāora pāmahana tihi. E whakaatu ana te tātari hua ōhanga i ngā pānga nui o te Wera Nui, inā koa i roto i ngā rāngai hangahanga, hangahanga, me te ahuwhenua, kei reira ngā mahi o waho e aro ana ki te whakaiti i te mahi i ngā wā wera nui. Kua puta te whakahaere rauemi wai hei wero nui o te Wera Nui, me ngā tono whakataetae mai i ngā pūnaha ā-tāone, ngā whakaritenga whakamatao whakaputa pūngao, me te whakamakuku ahuwhenua e hanga ana i ngā pakanga tohatoha e kino haere ana nā te iti o ngā taonga. Ko ngā urupare hoahoa o nāianei ko ngā hoahoa whakamatao kore mahi matatau, ngā hangarau karāhe atamai, me ngā pūnaha tuanui tipu e aro nui ana ki te whakaiti i te Wera Nui i roto i ngā paerewa mahi whare. Ko ngā mahi auaha o te whakamahere tāone e whakauru ana i te kaha o te Wera Nui mā roto i ngā ara matomato whānui, ngā rauemi papa whakaata, me ngā āhuatanga wai horihori i hangaia hei whakaiti i ngā pāmahana taiao i ngā tauine rohe. Ko te huringa pūnaha pūngao e whakanui ake ana i te kaha o te Wera Nui mā roto i te whakaputanga whakahou tohatoha, te rokiroki tauine whatunga, me ngā kaupapa urupare tono e pupuri ana i te whakamatao nui i ngā wā tino nui. Ko te rangahau ahuwhenua e arotahi ana ki te whakawhanake i ngā hua e kaha ana ki te āhuarangi i hangaia motuhake hei pupuri i te hua i raro i ngā āhuatanga Wera Nui i matapaetia mō ngā ahuatanga o waenganui o te rautau. Ko ēnei wero maha-āhuatanga e whakanoho ana i te Wera Nui hei pokapū matua mō te whakamahere urutau āhuarangi, te auahatanga hangarau, me te whakawhanake kaupapa here e aro ana ki te whakarei ake i te kaha o te hapori ki ngā wā tino kaha o te wā e matapaetia ana puta noa i ngā tekau tau e haere ake nei.
