The Cook Islands is holding a by-election on the outer island of Mitiaro tomorrow, which has the potential to produce a hung parliament.
The by-election follows an election tie in July between Tuakeu Tangatapoto of the Cook Islands Party and the island's previous MP, Tangata Vavia of the Democratic Party, with each of them getting 50 votes.
On election day, the Cook Islands Party won 12 seats, the Democratic Party nine and the newly formed One Cook Islands Movement secured two seats.
If the Democratic Party wins the by-election, the One Cook Islands Movement, with its two seats, could be king maker.
Last month, the caretaker Prime Minister, Henry Puna, denied there was a risk of constitutional crisis and internal party splits, saying he would engage in talks with One Cook Islands leader Teina Bishop if needed.
