He taputapu puna rau āhua-U tēnei hua, i hangaia mō ngā mīhini ahuwhenua, he mea hanga ki te maitai puna kaha-teitei e hurihuri tika ana. Hei wāhanga matua o te hononga i waenga i te pūnaha whakatārewatanga me te taputapu, he whānuitia te whakamahinga i roto i ngā pūnaha whakatārewatanga tarakihana, ngā mīhini rui, ngā harore kōpae, me ngā hanganga tautoko me te ārai mō ngā taputapu parau whenua.

He tino pai te tiaki i te parenga me te taumaha nui
Ina mahi ana i ngā mara pukepuke, i ngā mara pōkarekare rānei, ka whakamahia e ngā puna rau āhua-U tōna kaha āhua rerekē hei mimiti i ngā pānga pakeke inamata mai i te whenua. Mā tēnei tikanga hononga rapa ka taea e te mīhini te "ngāwari", ka hiki aunoa ina tūtaki ki ngā toka, ki te oneone pakeke rānei, ā, ka tere te tautuhi anō i muri i te haerenga, kia kore ai e pakaru, e hē rānei ngā wāhanga mahi nui pērā i ngā keri me ngā rake nā ngā tukinga pakari, ka tino whakaiti i ngā utu tiaki.

Te tārua i ngā mahi kāinga me te pumau o te pēhanga
Mā te hanganga āhua-U ka whakaratohia he wāhi mahi whakapūmau maha-ahu, ka taea ai e te wāhanga rui, e te rōpū rake rānei te urutau motuhake ki ngā nekehanga o te mata, me te whakatutuki i te whai i te āhua tika. Mā tēnei ka whakarite kia ōrite te hohonu o te rui me te rite o te pakaru o te oneone, ka whakatau i te raruraru o te "maroke o ngā purapura" me te "hohonu rawa" i puta mai i te whenua kāore i te ōrite.
