"As well as aggressive re-sizing to manage costs, in the medium to longer term Unitec has additional land surplus to educational needs that can be used to raise future capital," TEC said.
The institute has already sold a large part of its land to the Government for an intensive housing development, but that capital was already earmarked for rebuilding the Mt Albert campus on a reduced site.
Interim chief executive Merran Davis told Radio NZ that it would need to cut 100 to 200 of its current 1200 fulltime-equivalent jobs to achieve a target 20 per cent cost reduction.
A spokesman, Nick Wilson, told the Herald that exact numbers were still being worked through.
He said existing students would be able to complete their courses in all 19 programmes that were being closed to new entrants.
Tertiary Education Union president Dr Sandra Grey said the union hoped that a slight upturn in enrolments in the second half of this year indicated that student numbers would not drop to 6000 next year as forecast, so the cuts could be moderated.
"We are hoping that we can stop some of the closures of some of the programmes," she said.
She says staff have known for a while Unitec is in a rough financial position and that jobs are going.
She says they're disappointed it's all happening very quickly, and there isn't a lot of time for staff to think about the changes and make representations.
But Wilson said that the slight upturn in enrolments this semester was mainly in part-time students, so equivalent-fulltime numbers were still falling.
All polytechnics have been hit by a dual whammy of falling domestic enrolments, as a booming job market has encouraged young people into jobs rather than training, and falling international students caused by tightening immigration rules aimed at stopping students using low-level education as a route to NZ residency.
Hipkins has appointed Murray Strong as a commissioner to replace the previous Unitec Council.
