The Sydney-based Fiji Democracy and Freedom Movement says giving village elders the power to flog offenders would be a violation of human rights.
The comment follows the interim administration's announcement of a proposal to empower village elders to fight lawlessness.
The plan would allow flogging in some instances and includes restrictions on women's attire as well as a student curfew.
The movement's president, Usaia Waqatairewa, says it's another example of a very small group of people deciding what's good for Fiji's silent, uninformed majority.
"We taking Fiji back to the colonial days of the last century. In three years they just keep on saying to us that we have to go back to the bad old days. Fijians are much more educated now and they have developed the ability to think for themselves. They're talking about equality for everyone but they're trying to introduce new rules and regulations specifically just for indigenous Fijians."
