A University of Papua New Guinea student leader Hercules Jim says protesting students are not being bribed to demonstrate against the prime minister Peter O'Neill.
The students have been staging meetings and staying away from classes in an effort to get Mr O'Neill to step down to face corruption allegations.
Mr Jim who is on the Student Representative Council said there have been claims students are being bribed to protest.
But he said they have raised their own funds to conduct meetings and a boycott so far.
"What the minister for Higher Education is saying is baseless, he doesn't have any proof so we want to tell the world and the nation that we aren't politically motivated as the Prime Minister said or receiving bribes as the Minister for Higher Education said but we are driven by the passion to see justice prevail in our nation. The rule of law must be upheld and that's it."
Mr Jim said a formal vote to continue a class boycott at the university's campus in Port Moresby is expected this morning.
