He and two others, Heinui Lecaill and Vito Maamaatuaiahutapu, are alleged to have misspent money of the association running a local radio station Radio Tefana.
The accusations stem from a public accounts audit of 2009.
No charges have been laid yet.
Last month, Mr Temaru lost his assembly seat over campaign account irregularities.
