Callum Fredric, in a statement to the Otago Daily Times last night, said he had been advised by his lawyer ''not to discuss the incident as it is an employment issue''.
''However, I hope to continue as Critic editor...''
Senior Sergeant Brian Benn confirmed police were called to the office off Cumberland St just before noon, following concerns a ''former staff member'' was refusing to leave.
Campus Watch staff were also present and had also asked the man to leave, before police were called.
''When the policeman asked him to leave he did so, and that was the end of that,'' Snr Sgt Benn said.
It is understood the matter escalated over a possible staff appointment. The Otago University Students' Association (OUSA), which backs Critic and Radio One, receives much of its funding from the university rather than directly from students as a result of the Voluntary Student Membership Act (2011).
OUSA general manager Darel Hall declined to make any comment concerning the dispute. Mr Fredric and the university also avoided discussing the conflict.
A spokeswoman said Otago University would be making ''no response'' in regard to the matter.
The magazine, established in 1925, this week published its tenth issue for 2013, in which Mr Fredric was listed as editor.
