Instant-runoff voting
All elected members are chosen via Instant-runoff voting. Each of the 33 constituencies defined under Part 8 of the Constitution elects a single member to the House. Additionally, the North Bougainville District, South Bougainville District and Central Bougainville District each elect a woman representative and a former combatant representative who fought with the Bougainville Revolutionary Army during Bougainville's armed struggle for independence from Papua New Guinea. A 41st representative, the Speaker, is appointed externally by the elected members.
