All of the arrested borrowers reached a repayment agreement with Inland Revenue.
Officials say the measure is only used for the most serious defaulters and after repayment requests are ignored or unsatisfactory responses received.
Cook Islander Ngatokotoru Puna, 40, was arrested as he tried to leave New Zealand in January last year - the first time the hardline arrest powers were used since being introduced in March 2014.
Puna, who has lived in the Cook Islands for 13 years and whose $40,000 loan had ballooned because of interest and penalties, borrowed $5000 from his parents to pay the IRD before it was satisfied he could leave the country.
A student loan annual report for the year to June 30 shows that the overdue amount was $1.2 billion in the past year, an increase of 12.4 per cent from 2016.
The increase in both the overdue amount and the average amount outstanding was mainly driven by defaulting overseas-based borrowers. They now owe $1.1b in overdue repayments, compared with the $99m owed by New Zealand-based borrowers.
The student loan annual report also shows the amount of debt wiped because of bankruptcy has risen from $17.6m to $19.9m. Debt written off because of death dropped to $12.6m.
Labour will next year introduce a year of free tertiary or post-school study. Hipkins said the student loan annual report showed students were leaving study with higher debt and taking longer to pay it off.
"Fewer students are going on to study at a post-school level. Students are telling us that they have been put off by higher costs and the burden of debt. It is a worrying trend and robbing too many Kiwis of opportunities and employers of the skills they need."
