There's an expectation it will take two years to get the number of international students in vocational education back to pre-Covid levels.

There were about 75-thousand international students in New Zealand last year - 40% less than a peak in 2016.

Te Pukenga is being disestablished by January, with power then going back to individual Polytech's.
