I ngā tau tata nei, me te whakapai tonu i te mōhiotanga taiao me te arotautanga o te hanganga pūngao, kua piki haere te maha o ngāpounamu karāheKua tīmata ngā kaihanga ki te huri i ngā oumu tuku iho ki ngā oumu hau katoa. Nō nā tata nei, he maha ngā putanga mīhini whāngai kua hurihia hei tikanga whakamahana hiko. Tāutahia ngā tokotoko waro hiko hiko pāmahana-tiketike ki tētahi ōwehenga i roto i te peihana rauemi, ā, mā te whakarerekē aunoa i te pāmahana, ka taea te whakahaere i te huringa pāmahana i roto i te peihana rauemi i roto i te 5-10 nekehanga. Mā tēnei whakapainga ka ōrite ngā pata rauemi o te mīhini whāngai, me te ngāwari pai, ā, ka whakaoti katoa i te raruraru pumau o te wai karāhe. I te wā e hanga ana i tētahi mīhini hanga pounamu, mā tēnei pumau ka tino ngāwari te whakamahi i te rauemi, ā, ka tino whakapai ake i te tere hanga pounamu.
I roto i te whakaputanga ongā pounamu karāhe, ka whakamahana, ka whakarewa hoki te oumu i ngā rauemi mata e whakamahia ana hei hanga pounamu karāhe, ā, ka tukuna e ngā mīhini tapahi me te whāngai aunoa ngā taumaha me ngā momo rauemi rerekē ki ngā mīhini hanga pounamu i raro nei hei whakaoti i te hanga pounamu karāhe. Heoi, he mea nui te pumau o ngā pata karāhe hei hanga pounamu karāhe kounga teitei.
I ngā wā o mua, he maha ngā wheketere pounamu karāhe i whakamahi i ngā oumu haurua hei oumu. He rerekē te pāmahana o te wai karāhe i roto i te peihana whāngai o te mīhini whāngai, ā, he rerekē anō hoki te rahi o ngā pire wai karāhe i tapahia. I ētahi wā, ko ngā pū hinu anake (ngā pupuhi mamaoa) me ngā kōhao tirotiro ka taea te whakamahi hei whakatikatika āta. Ka hua ake tēnei i te kore pumau o ngā tautau wai karāhe, he uaua ki te whakahaere, ka hua ake he nui te maha o ngā pounamu karāhe hapa, ā, ka pā ki te whanaketanga o ngā wheketere pounamu karāhe.
Hei whakaoti i tēnei raruraru, he maha ngā wheketere pounamu karāhe e whakamahi ana i ngā oumu hau katoa, ā, kua whakapai ake hoki i ngā mīhini tapahi me te whāngai aunoa. Ināianei, kua tāutahia ngā tokotoko waro hiko hiko pāmahana teitei ki roto i te peihana rauemi o te mīhini whāngai. Mā te whakarerekē aunoa i te pāmahana, ka taea te whakahaere i te huringa pāmahana i roto i te peihana rauemi i roto i te 5-10 nekehanga. Mā tēnei whakapainga ka ōrite ngā pata rauemi o te mīhini whāngai, me te ngāwari pai, ā, ka tino whakaoti i te raruraru pumau o te wai karāhe. I te wā e hanga ana i tētahi mīhini hanga pounamu, mā tēnei pumau ka tino ngāwari te whakamahi i te rauemi, ā, ka tino whakapai ake i te tere hanga pounamu.
Hei whakarāpopototanga, mā te whakapai ake i te hoahoa o te oumu me te whāngai tapahi aunoa, kua pai ake te pumau o te wai karāhe, kua whakaitihia te tere hapa o ngā pounamu karāhe, ā, kua pai ake te whai huatanga me te kounga o te whakaputanga.wheketere pounamu karāhekua whakapaitia.
