New research has uncovered how many university staff are working in non-academic roles.
The New Zealand Initiative study found there are up to 50 percent more non-academics than academics.
Compared to other countries, New Zealand has the highest ratio of non-academic to academic staff.
Research fellow and Victoria University professor Dr James Kierstead says they're not recommending universities just cut those roles - but it is a major cost.
He says New Zealand universities spend about 45 percent of their total wage expenses on non-academic salaries.
