    Hei tāpiritanga, he tino pai te ātete o ngā paipa maitai porowhita kua whakapirihia ki te waikura, he mea nui tēnei ki tepaipa hau māorite hanganga. Nā ngā āhuatanga ā-roto o te maitai me ngā paninga me ngā arai matatau, ka tino ātete ēnei paipa ki ngā pānga waikura o te hau māori me ētahi atu poke kei roto i te taiao. Ehara i te mea ka roa ake te ora o te paipa, engari ka whakaitihia hoki ngā whakaritenga tiaki me ngā utu e pā ana.

    Haunga ōna āhuatanga ātete miihini me te waikura, he pai rawa te paipa whakarewa porowhita mō te tāutanga i roto i ngā momo whenua me ngā āhuatanga taiao. Nā tōna ngāwari ka māmā ake te nekeneke me te tāutanga i ngā arai, ka waiho hei kōwhiringa utu-pai mō ngā whenua uaua. Hei tāpiri, he kaha ngā hononga whakarewa o ngā paipa porowhita, kia kore ai e turuturu ngā paipa puta noa i te roanga o te wā mahi.

    Ko tētahi atu painga o te paipa whakarewa porowhita ko tōna utu iti. Mā te tukanga hanga ka taea te whakaputa tere me te whakamahi pai i ngā rauemi mata i te utu whakataetae ki te whakataurite ki ngā rauemi paipa kē atu. Hei tāpiri, ko te roa me te iti o ngā whakaritenga tiaki o te paipa whakarewa porowhita ka āwhina i te whakaiti i ngā utu huringa ora, ka waiho hei whiringa whai hua mō ngā kaupapa paipa hau māori.

    Heoi anō, nā te ngāwari o ngā paipa whakarewa porowhita, he pai mō ngā momo diameter, matotoru pakitara me ngā taumata pēhanga hei whakatutuki i ngā hiahia kanorau o ngā pūnaha tuku hau māori. Mā tēnei whānuitanga ka taea te whakapai ake i ngā hoahoa paipa kia tutuki ai ngā whakaritenga whakahaere motuhake, kia tino pai ai te mahi me te whai huatanga.

    Hei whakarāpopototanga, ko te whakamahinga ongā paipa maitai porowhita kua whakapirihiaHe maha ngā painga o te hanganga paipa hau māori, tae atu ki te kaha teitei, te ātete ki te waikura, te ngāwari ki te urutau me te whai hua o te utu. Nō reira, koinei tonu te whiringa tuatahi mā ngā tohunga ahumahi e rapu ana i ngā otinga tuku hau māori pono, roa hoki. Mā te whakamahi i ngā painga o ngā paipa porowhita kua whakarewahia, ka taea e ngā kaipupuri hea te whakarite kia mahi haumaru, kia whai hua, kia pumau hoki ngā hanganga hau māori mō ngā tau e haere ake nei.
