Hanganga Tautoko Tākai Porowhita Ukume Ātete Waikawa Kotahi/Rua mō te Pourewa Waikawa Whāwhā
Hanganga Tautoko Tākai Porowhita Ukume Ātete Waikawa Kotahi/Rua mō te Pourewa Waikawa Whāwhā
E mōhiotia ana hoki ngā āwhata pōro uku ko ngā āwhata pōro uku, ko ngā āwhata pōro uku ātete waikawa rānei, nā te mea he mea tukatuka pai mā te whakamahi i ngā matū uku ātete waikawa. Ko ngā rauemi mata taiao kua tīpakohia ka hangaia ma te āta mā roto i te raupapa o ngā mahi tukatuka pēnei i te hoahoa tauira, te mira pōro, te whakamahine paru, te hoahoa pokepokea ai, me ērā atu. He ātaahua, he ātaahua hoki te āhua o te āwhata porowhita i hangaia, ā, ko ngā whakaritenga me ngā inenga e tutuki ana i ngā whakaritenga tāutanga o te tinana pourewa.

1. He ōrite te tohatoha o te hau.
2. Te kaha ā-mīhini teitei.
3. Te tauwehenga haumaru teitei.
4. He pumau pai.
5. He ātete kaha ki te waikura.
6. Ā, he watea te hanganga.
7. Te roa o te ora ratonga.
1. Pereki āwhata Ko te wāhanga hanganga matua o te āwhata porowhita he tāera uku he āhua 'āhua-I' te āhua, nō reira e mōhiotia whānuitia ana ko te 'pereki āhua-I'.
2. Pereki waewae āwhata Ko te wāhanga o raro o te āwhata porowhita he tāera uku he tapatoru te āhua, he trapezoidal rānei kei raro.
3. Te uho o te āwhata He hanganga kōniko te wāhanga o waenganui o te āwhata porowhita, ā, kei roto he āhua ripeka.

He rauemi tino pai ngā āwhata pōro uku, ā, he whakakī pourewa whai hua hoki mō te aukati i te waikura i roto i ngā whare ahumahi pēnei i te hanga kōka me te waikawa whanariki (pēnei i te hau hiku whakarewa hei whakaputa waikawa, te pyrite hei whakaputa waikawa, me te whanariki hei whakaputa waikawa), tae atu ki te tongi, te whakarewa, te ahumahi māmā, te hinu matū, me ētahi atu ahumahi.
