The latest victim of the Electoral Finance Act looks set to be the bumper sticker.
The Chief Electoral Officer has written to party secretaries to emphasise that anyone driving around with a party political bumper sticker on election day, could be breaking the law.
Electoral law stipulates that all party hoardings and political advertising have to removed from public view by midnight before election day.
That law is not new, but Chief Electoral Officer Robert Peden says the Electoral Finance Act has prompted increased awareness of such issues.
He says anyone caught with a political bumper sticker on election day could be liable for a $20,000.
However there is a defence, if the sticker was not displayed knowingly or deliberately.
