UCOL Whanganui campus manager Bronwyn Paul said a key reason for the split was the campus' Bachelor of Nursing Programme.
"It is our most significant programme regarding student numbers, and it is an industry that has traditionally attracted more females," she said.
Paul also said a higher proportion of men were entering industry training and apprenticeship programmes rather than enrolling at universities or polytechnics.
Encouraging diversity across UCOL and at a programme level was vital.
"We are always looking at how we can offer new study options to encourage diversity and cater to potential learners' needs."
Paul expected UCOL's transition into Te Pūkenga would also help to provide a safe and welcoming space for all learners.
"Moving into Te Pūkenga will allow us to provide learners with more options and flexibility about when, where, and how they study – this approach will help those who are juggling work, raising children, [and] supporting family members," she said.
