The dividing line between the two moieties was the old coastal road named "Hala Fonua moa" (dry land road). Modern chiefs who derive their authority from the Tui Tonga are still named the Kau Hala Uta (inland road people), while those from the Tui Kanokupolu are known as the Kau Hala Lalo (low road people). Concerning the Tui Haatakalaua supporters: when this division arose, in the 15th century, they were of course the Kauhalalalo. But when the Tui Kanokupolu had overtaken them they shifted their allegiance to the Kauhalauta.
