An independent candidate, Elias Kapavore, has won the by-election in Papua New Guinea's Pomio Open electorate.
The Electoral Commission declared Mr Kapavore the winner, beating the former East New Britain governor Francis Koimanrea of the Peoples Democratic Movement after the count went down to preference votes.
The Pomio seat became vacant last year when the incumbent Paul Tiensten was given a nine-year jail term for being convicted on corruption-related charges.
Mr Kapavore is the former chief executive officer of Vanimo General Hospital and although he ran as an independent, is expected to be the subject of lobbying to join the ruling People's National Congress.
The PNC's candidate in the Pomio by-election, Francis Waina, finished third.
