Tuatahi, he nui rawa te ngaohiko i roto i te ara iahiko, ka arahi ki te pakaru o ngā pūnga kiriata.

Ko te tawhā tino nui o te pūnga kiriata ko te ngaohiko mahi whakatauranga. Mena he nui rawa atu te ngaohiko i runga i te ara iahiko i te ngaohiko mahi whakatauranga o te pūnga kiriata, i raro i te mahi a taua ngaohiko teitei, ka puta he tukunga wāhanga kaha me te kino hiko-kore i roto i te pūnga kiriata, ka arahi pea ki te pakaru o te pūnga.

Tuarua, he tino tiketike rawa te pāmahana.

He pāmahana whakahaere kua whakatauria mō ngā pūnga kiriata katoa.

Ko te nuinga o ngā pūnga kiriata i hangaia e CRE he ātete pāmahana mōrahi ki te 105℃. Mēnā ka whakahaerehia te pūnga kiriata i te pāmahana teitei ake i te mōrahi e whakaaetia ana mō te wā roa, ka tere ake te koroheketanga wera o te pūnga, ā, ka poto ake te ora. I tētahi atu taha, i te tāutanga me te whakamahinga o ngā pūnga, me aro nui ki te hauhautanga, te whakamarara wera, me te irahiko i raro i ngā āhuatanga mahi tūturu, kia taea ai te whakamarara i te wera i puta i te whakahaere o ngā pūnga i roto i te wā, ka taea ai te whakaroa i te ora ratonga o ngā pūnga kiriata.

Hei whakamutunga, ko te hoko i ngā pūnga kiriata kounga-kore.

Ināianei kua tino pōhēhē te umanga, nā te mea he pakanga utu nui kei te mākete. Ko ētahi kaihanga, kia pai ake ai te whakataetae utu o ā rātou pūnga hiko, ka whiriwhiri ki te whakamahi i ngā pūnga hiko iti-ātete hei whakaari i a rātou he pūnga hiko teitei, ka arahi tēnei ki te raruraru kāore i te rawaka te ngaohiko tuturu o te pūnga hiko, ā, ka ngāwari hoki te pakaru o te pūnga hiko kiriata nā te ngaohiko teitei.
