The Electoral Commission has referred 48 voters to police for voting more than than once at the 2020 general election.
Voting more than once carries a penalty of a jail term of up to two years and/or fine of up to $40,000 or up to $10,000 if the court decides it was at the lower end of the scale and not a deliberate attempt to manipulate the election result.
Under the Electoral Act "personation" is considered a corrupt practice, including voting as another person or voting more than once.
As these matters are now with the police, the Electoral Commission will not be commenting further, a spokesperson said.
