Fiame Naomi Mata'afa, the leader of the FAST party, told RNZ her party won the majority of seats in the 9 April election and could form a government, which she believed should happen early next week, despite opposition from the caretaker government.
Her party is now waiting on the Head of State to decide his next step.
"The due process is to confirm our numbers with the Clerk of the house, and through him ask the Head of State to reconvene parliament, so we've done that," Fiame said.
