The latest mean repayment period was 8.4 years, though for those who stayed in New Zealand it was two years shorter.
Six and a half years does not seem too onerous, though it probably means saving for a house cannot start until the person is in their late 20s.
And with house prices at the levels they are, most young people will need more parental support to have much chance of financing their first home.
If it were not for the crippling cost of houses today, and the associated level of rents, the long lamented student loan scheme would probably sit more comfortably with today's generations of students and parents. The scheme has been around now for 25 years.
Many of those who first took out loans will be soon be parents of tertiary students if they are not already.
The generations that remember when university courses cost no more than a nominal few hundred dollars are in their 50s and 60s or older.
They can still be wracked with guilt when they see young people going into debt for further education. But they forget, perhaps, that much more tertiary education is provided today.
All sorts of occupational training involves institutional learning nowadays. If all tertiary education was free and financed entirely by the taxpayer, the quantity would need to be restricted.
Student loans are part of the fabric of life now and have helped make New Zealand better off.
