TI Vanuatu's chairman, Dr Willie Tokon, said he had received about a dozen reports, including some landowners who threatened to shut down a school if people didn't vote for a particular candidate.
He said the alleged incidents were largely in rural areas, away from those polling stations manned by international observers.
"These reports are coming from Banks and Torres in the north, Ambae, Pentecost, and Ambrym - all the rural areas. Vila and Santo were pretty clean because we had these international monitors here, but these reports are coming mainly from the islands."
