Ka hangaia te paipa maitai kore hononga, kāore he whakarewa mā roto i ngā tikanga mahi wera pērā i te huri wera poka. Mēnā e tika ana, ka taea te mahi matao anō i te paipa mahi wera kia rite ki te āhua, te rahi me te mahi e hiahiatia ana. I tēnei wā, ko te paipa maitai kore hononga te paipa e whakamahia nuitia ana i roto i ngā wāhanga hanga matū hinu.
