French opposition parliamentarians have formed a committee aimed at ensuring that French Polynesia's by-election planned for February will be fair.
They say there is a risk of cheating as the Gaston Flosse system fights for its survival.
One MP, the former overseas territories minister Christian Paul, says the election for Tahiti and Moorea has to be held without any doubts or suspicions.
Another MP, Paul Dosiere, says there is a risk that fictitious names will be put on electoral lists.
And a senator, Dominique Voynet, says international observers should be sent to monitor the election of 37 of the assembly's 57 MPs.
Mr Flosse lost the presidency in the May general elections but last month, the French supreme court annulled the result in the electorate he lost, citing irregularities that favoured the parties opposed to him.
