Tasman Island in the Atolls constituency of North Bougainville is the final constituency yet to complete polling in the election in the Papua New Guinea region of Bougainville.
Counting is due to start next Tuesday, once all ballot boxes are received.
Polling officials for Tasman Island are still at Mortlock Island, and have been prevented from reaching Tasman Island due to bad weather.
The Office of the Bougainville Electoral Commissioner has already arranged with the management of Bougainville's latest flagship, the MV Rapois Chief to travel to Mortlock and transport the polling officials to Tasman.
The vessel was expected to leave Buka last night and is due to arrive at Mortlock today.
The office says voting will commence as soon as the vessel arrives in Tasman Island.
