Another Fiji cabinet minister, a senator and three former members of parliament are likely to be the next five high profile people facing treason-related charges.
The Daily Post reports that they are alleged to have taken oaths to join George Speight's rebel administration during the coup.
The head of police criminal investigations, Waisea Tabakau, has confirmed that the five new people are under investigation and New Zealand police are verifying their signatures on their swearing-in documents.
Assistant Superintendent Tabakau says they're collecting hard evidence against the five, and he's asking the public to come forward with information.
Mr Tabakau says the former prime minister, Sitiveni Rabuka, has also been questioned about his role in the removal from office of the president, Ratu Sir Kamisese Mara, and the file, on this issue's, still open.
The revelations of more charges come as vice president Seniloli, sports minister Leweniqila, deputy Speaker Vakalalabure and three others stand trial for treason for being worn into Speight's failed administration
