Murielle Meltenoven has received reports of candidates, who are also seasonal work agents, advising their clients to vote for them.
Ms Meltenoven told the Vanuatu Daily Post she had a video clip of an agent urging seasonal work applicants to vote for him if they wanted him to be sent overseas.
But the Commissioner said agents who acted in such a way would be dealt with according to the law.
There are 231 candidates campaigning to be part of the country's 52-seat Parliament.
The general election is set for 19 March.
