The government has also placed on special leave the Deputy Vice Chancellor (academic and research) Peseta Desmond lee Hang and Deputy Vice Chancellor (Corporate Services) Maugaoali'I Ufagalilo Mualia.
The Samoa Observer quoted the Minister of Education Sports and Culture Loau Keneti as saying that cabinet's decision was based on the recommendation of the NUS Council.
He said allegations against the Vice Chancellor and two Deputy Vice Chancellors warranted an internal investigation to clear up the air.
According to the minister there were complaints from the public about some students who should have graduated and those that shouldn't have and he hopes the investigation will help clarify what exactly happened.
The NUS Council forwarded its recommendation to the cabinet last week before the NUS graduation and cabinet acted on the recommendation Wednesday.
The decision to suspend the vice chancellor and the two deputy vice chancellors was effective immediately.
