The FijiFirst party is calling on the Electoral Commission to address intimidation of its supporters.
A party official and Fiji's Attorney General Aiyaz Sayed-Khaiyum says vehicles carrying the party's stickers have been stoned and drivers harrassed in recent weeks.
Sally Round reports from the Fiji capital.
"The rear windows of many Fiji taxis are plastered with the FijiFirst poster which carries the image of its leader Frank Bainimarama.
Others carry flags but many say it's too dangerous to carry the logo and it's not worth the cost because of likely damage to their vehicles.
FijiFirst says some drivers now want the stickers removed.
Mr Sayed-Khaiyum says some members of the police force, Land Transport Authority officials and members of the public are also harrassing the vehicles drivers and their passengers and he's accused some officers of promoting their own political agenda.
He says the Electoral Commission needs to step in and give people confidence they can express themselves."
