E whakapau kaha ana mātou ki te whakarato hea parau e whakakotahi ana i te pakeke me te pakari, me te whai kia whakaitihia te auau o te whakakapinga me te whakapai ake i te whai huatanga o te ahuwhenua.

Hei ārai i te kaha o te pakaru me te pānga i raro i ngā āhuatanga oneone rerekē, ka hangaia tēnei hua mā te whakamahi i ngā tukanga matua e whai ake nei:

He rino motuhake: Mā te whakamahi i te rino koranu konupora-nui, te rino boron rānei hei rauemi turanga, he tino pakari te pānga, ka taea te tu atu i ngā pānga ohorere mai i ngā mea pakeke pēnei i te kōhatu me ngā pakiaka rākau, ā, kāore e ngawari te whati, te pakaru rānei.

He penapena wahie, he tino whai hua: Mā te koki urunga koi ka whakaiti i te ātete ki te parau, ka penapena i te 5%-10% o te wahie e ai ki ngā whakamātautau tuturu, me te whakarato hoki i te kaha pakaru oneone me te kapi piri.

Hototahi tino pai: Kei te wātea i roto i ngā whakatakotoranga me ngā tauira rerekē, he tino hototahi ki ngā huihuinga parau mai i ngā waitohu nui o te motu me te ao (pēnei i a Recon, Besson, Grigor, me ngā momo parau whakairi o te motu).
