Craccum co-editor and article author Dan Meech said he was "weirded out by the depth" of the monitoring.
The person who gave the magazine the file called it "one of the most bizarre documents" he had ever seen.
The university released a statement to Craccum, stating the monitoring was to understand the "sentiment and vibe" of students on "important issues".
The Microsoft Word document covers from late March through to October this year and contains near-daily bullet-pointed entries from Facebook, Twitter, TikTok, Instagram and Reddit, with links to posts students wrote over the period.
Names are seldom included in the document, but several links click through to students' personal social media pages.
Many links go to anonymous posts on university "confessions" Facebook pages.
While the document is not publicly accessible, it is not password-protected.
Some entries are linked to university study, including "Student wondering what will happen with online exams after we return to campus", with a link to a Reddit post. In other threads, students seek advice on which papers to take.
Many other entries, particularly from the anonymous "UoA: meaningful confessions" page, are highly personal posts about romantic relationships, breakups, mental health, physical matters and sexuality, with no clear link to the university.
"Post from a student struggling to lose weight, helpful comments," one said, with a link to the anonymous post.
"Confession about the pain and emotions related to periods," said another, also anonymous.
"Post asking how to get an item delivered without the family asking questions (sex-related item)," and "Post wishing for better friends," another read, all anonymous.
"Post about lack of privacy for masturbation in lockdown," was included.
Another: "Post questioning whether to get back with her ex (from a student who doesn't even go here!)."
As the year goes on, each day's entries generally lengthen. Some days have 30 or more entries, and are divided into themes: academic, online exams, graduation, return to campus, mental health/wellbeing, campus life, memes, and personal.
Meech said access to the document came fortuitously through a mostly unrelated Official Information Act request to the university.
He was shocked when he saw the extent of it.
"I think it is an over-reach," Meech told RNZ.
"It does make you feel a little bit uncomfortable when you're studying at the university and publishing things online," he said.
"I can see that from the university's point of view, it might be good to be able to gauge a view of what students are thinking, but the depth to which it was going into ... I just found it a bit bizarre that the university was monitoring erotica stories and students talking to other students about ... the price of muffins."
The fifth-year arts and law student does not know how many people had access to the file.
Access allows people to click through to students' social media profiles.
Meech said it was an odd use of resources at a time when the university was struggling financially.
A University of Auckland statement sent to Craccum said:
"We know that students communicate about and respond to issues via social media and looking at what is being posted is one of the ways that the university listens to the student voice and gets a sense of the student sentiment in real time.
"We collate views that have been posted on public channels and use it to understand the views and sentiments of students on important issues.
"We don't take note of any individual students but observe themes, sentiment and vibe of the student body."
RNZ has requested further comment from the university.
