He was the third son of Uluilakeba I and last recorded member of the noble household, Naivi, to hold the title Roko Sau of the Lau Islands.
On hearing of his nephew's treachery, Matawalu returned from Bau and reasserted his authority, while Dranivia was touring the Southern Lau islands.
His attempt was thwarted however as Malani's relative, a son of Delailoa residing on Nayau, warned him of Dranivia's impending plans.
This information enabled Malani to crush Dranivia's forces and removed him from any further rebellions.
It was due to the subduing of Dranivia, head the elder noble house of Naivi, by the younger noble households of Matailakeba (Malani) and Vatuwaqa (Taliai Tupou) that has completely eliminated any members of Naivi, the right to contest for the title of Tui Nayau to this day.
