[Bionicle G1] What did the inhabitants of Ta-Metru do with all the masks they made?

Ta-Metru is described as being a district of forging and building, and one of the things they made was kanohi. But apparently they made Great and Noble Kanohi in addition to the powerless masks the Matoran wore. So since Matoran can't use kanohi with power, what did Ta-Metru do with so many masks that the population of Metru Nui couldn't use, and why did they keep making them?

Back then, there were a lot more Turaga and Toa. You only see Lhikan because there was actually a secret extermination campaign against the Toa during that time. During the heyday of the Toa, plenty of Great masks would be sent to Toa teams all over Mata Nui's body.
