The Nauru government has rejected claims made by opposition candidates that local media is refusing to broadcast their campaign advertising.
The general election is on Saturday when about eight thousand eligible voters must cast their ballots or pay a $US15 dollar fine.
The Communications Minister, Shadlog Bernicke, said the opposition knows that Nauru TV and radio have a long standing policy of not airing political advertising from either side.
Mr Bernicke said the opposition is using foreign media to make untrue claims against the Government and influence international election observers.
Opposition candidates have also alleged political interference prevented them from staging a rally last weekend.
