ngaiaku kāore e mimiti i te wai – he mea pai tēnei mō ētahi kaupapa, engari ko te tikanga anō hoki ka honoa te papanga nairona me te nekehanga hei hanga hiko pateko. He rite te āhua me te āhua o te nairona ki te hiraka.

He pakari ngā muka nairona, he tino pīngore, he mama, ā, he iti noa te wai e mimitia ana e ngā muka nairona, nō reira he ngāwari te horoi me te whakamaroke i ngā kākahu i hangaia ki te nairona.

Mō te tuitui, kia maumahara ki te whakamahi i te kutikuti koi, i te taputapu tapahi kakahu hurihuri rānei hei whakaiti i te pakaru o te nairona. Muri iho, kia mau te papanga mā te kukume i te papanga i ngā taha e rua o te ngira, kaua e ngana ki te kukume i te papanga mā roto, kaua hoki e werohia te nairona ripstop.
