pou me ngā kaiwhakamātau whakamātau
He momo hanganga nui ngā tae whakanuia me ngā pūtē i roto i te whenua o te rōpū whakanuia, e mahi ana hei tuaropaki mō ētahi mahi whakanuia e rite ana i ngā rōpū hanga, haupatu, me ngā rōpū rangahau. Nā te hanga tūhono tohu nei i te wānanga me te hunga hiranga i te hunga hoki nei i te hunga hoko i ngā whenua katoa. Ko ngā tae whakanuia he hononga whakawehenga e whai ake nei i te kaha whakanuia me te kawe kaha mai i te mīhini whakanuia ki te pūtē, nō reira ko ngā pūtē he kaiwhakatū i te ara whakamutu i te whenua e whakanuia ana. Nō ngā wā o nāianei, ka hanga ngā tae whakanuia i te ahi kōkōwai matua, me ngā huatau rākau whiti kōwhiri e whai ake nei i te hononga tino whakapono me te whakatuku kaha motuhake. Ko ngā pūtē, e kitea ana i ētahi atu hanganga, pērā i ngā pūtē poro, ngā pūtē ara mata kararehe, me ngā PDC (Polycrystalline Diamond Compact), ka hanga hei whakarite i ngā take papa tūhonotia me ngā hiahia whakanui. Ka whakauru ngā kōmihana nei i ngā rautaki whakatara me ngā rākau tino whakahirahira e whai ake nei i te wā e taea ai e rātau te whakapakari i te wā o te mahi. Ko te hanga o ēnei taputapu ka tūhono ki te whakapakari i te hokohoko whakanuia, ahakoa te itinga o ngā wā e kore ai e taea te whakahoki, me ngā whakaaro hou pērā i ngā rāngai whakanui pai ake mō te whakamutu i ngā kereka, me ngā patapata kaha motuhake mō te waenganui o ngā wā.
