A candidate from last year's Papua New Guinea general election is urging the country to adopt a national ID-based voting system before the next poll.
De Kewanu, the former MP for Mendi in Southern Highlands, lost his seat in the election to government minister Michael Nali.
However due to frustrations over irregularities in the election, the province was plagued by bouts of violent unrest well into the middle of this year.
Mr Kewanu told Johnny Blades that many people were denied a fair vote due to practices such as block voting, while misuse of ghost names on the electoral roll was rife.
