WFA Ma te Whakakotahitanga o te Alumina/Waikura Konumohe/Waikura Konumohe/Korunuma
Whakaahuatanga Hua
He mea hanga te paura alumina mā kua hanumihia ki te paura alumina iti-konutai tino parakore, mā te rewa i te pāmahana tiketike, te whakamatao kia whakatiotia, kātahi ka kuru. Kei raro i te mana whakahaere pakari te paura waikura konumohe mā kua hanumihia kia mau tonu te tohatoha rahi o te kōpura me te āhua ōrite.
