Whakataki Hua

Ko te Pepa parahi he mea hanga mai i te parahi electrolytic, na roto i te tukatuka ma te ingot, te hurihuri wera, te hurihuri makariri, te maimoatanga wera, te horoi o te mata, te tapahi, te whakaoti, me te whakakii. He pai rawa te whakamaarama o te waiariki me te hiko, te ngawari ngawari me te pai o te aukati waikura. Kua whakamahia nuitia i roto i te hiko, te miihini, te whakawhitiwhiti korero, te taputapu, te whakapaipai me etahi atu ahumahi.
