Seventy UKZN students were arrested for public violence after they allegedly damaged classrooms at the university's Edgewood campus on Monday, KwaZulu-Natal police said.
The group would appear in the Pinetown Magistrate's Court on Tuesday, Captain Thulani Zwane said.
He said police were monitoring the situation. Last Monday, four students were arrested and lectures at the same campus were disrupted.
The university's spokesman Lesiba Seshoko said in a statement it was not aware of the reason for the protest as there had been no communication from students with university management.
Students across the country have taken part in protests recently to express their dissatisfaction over a shortfall of money in the National Student Financial Aid Scheme.
