Kepa stood again for Rewa in the 2006 election, defeating her nephew, Ro Filipe Tuisawau. She was reappointed as Minister for Education, Youth and Sports in the multi-party cabinet. When the Qarase government was deposed by the 2006 Fijian coup d'état, Kepa joined a court case challenging the legality of the coup. She also used her position in the Great Council of Chiefs to oppose the coup, and was instrumental in the Council's 2007 rejection of Epeli Nailatikau nomination as Vice-President. As a result, the Council was suspended.
