The study, led by Otago University's National Centre for Lifecourse Research, is the first major study to survey outcomes for international students as well as New Zealanders. It found that 48 per cent of international graduates had returned to their countries of origin, 43 per cent were still in New Zealand and 9 per cent had moved to another country such as Australia.
Almost 90 per cent of all the graduates said they would go to the same university again "if you could start over", but only three-quarters said they would enrol in the same qualification.
Three-quarters of the graduates had taken out student loans and still had a median student loan debt of $10,000 to $15,000.
Two-thirds said they were in a relationship and 27 per cent already had children, but 31 per cent were still single.
Only 7 per cent said they smoked cigarettes regularly in the past year, compared with 23 per cent of all New Zealanders aged 25 to 34.
The graduates were also more likely to have voted in the national elections (84 per cent) than the national average of 78 per cent.
