Ki te whakatauritea ki ngā tikanga tawhito pēnei i ngā pūtu me ngā waea, ko tēneiRawhi āhua-UKa taea te whakaoti i te honohono me te whakatika i te tauira me te kore e hiahiatia he taputapu āwhina, ka whakaiti i te wā e hiahiatia ana mō te mahi kotahi ki te hautoru o ngā tukanga tuku iho. Hei tāpiri, nā te hototahi ki ngā kōhao tauira paerewa 12mm, ka tino whakaitihia te ngaronga o te tukanga o te tapahi me te whakatikatika i te papaanga.

TeneiĀhua-UKo te rawhi i hangaia ki te rauemi maitai piauau he 40% noa iho te utu mō te kotahi wae o te pūtu mahi kotahi, ā, ka taea te whakamahi anō i ngā wā neke atu i te 200. Kua āwhina i te whakaiti i te utu hangarau o te kaupapa rerewē mā te 12%. Nā tōna mama me ōna āhuatanga ngāwari ki te kawe, he mea ngāwari ake hoki mō ngā kaimahi te mahi me ngā tauira teitei.
