LEGO did take all the ideas for BIONICLE from lots of other cultures and legends, so why not the name for the island, which they got from Rapa Nui (otherwise known as Easter Island), as there is not a Moto Nui as far as I can tell within several thousand miles of Easter Island.
Also Mata-Nui does not exist, it is made up by LEGO.
