Pae porowhita Aunoa 420 Tirotiro UT:
Mō te āhua porowhita, ka whakamahia whānuitia i roto i ngā mahi e hiahiatia ana he kaha teitei me te ātete pai ki te waikura. Nā tōna kaha ki te tu atu i ngā pāmahana teitei, he pai mō te whakamahi i roto i ngā taiao kāore e pai te mahi a ētahi atu maitai. Ka whakamahia te āhua porowhita o te maitai kowiri tira 420 mō ngā kaupapa maha, tae atu ki ngā toki, ngā toki, ngā taputapu, me ētahi atu wāhanga e hiahia ana he kaha teitei me te ātete ki te waikura. He mea nui kia whakarite kia tutuki ngā whakaritenga o te porowhita i ngā paerewa e hiahiatia ana mō tō mahi motuhake.
