The 2016 academic year was terminated following eight weeks of continuous boycott, protest, intimidation and arson.
UPNG acting chancellor Dr Nicholas Mann confirmed today that all students have left campus.
Dr Mann said students that were enrolled in 2016 will not reapply but only register again for the 2017 academic year.
He said only the 2016 Grade 12 students will apply for first year in 2017.
The university senate is putting in place a structure to accommodate the 2016 first year students and the new intakes.
Dr Mann stressed that 2016 semester two fees will be carried over to 2017.
He added that students who didn't clear their rooms will be responsible for damages done to their rooms, including loss of key.
The curfew is still ongoing at the main campus and residential area.
