New Zealand student loans are among the most borrower-friendly in the world. The key fact: your loan is interest-free while you live in New Zealand. This makes the NZ student loan fundamentally different from student debt in Australia, the UK, and the United States.
Living in NZ: 0% interest, though a $40 administration fee applies if your balance is $20 or more at 31 March
Living overseas: 5.6% per year interest on the outstanding balance (from 1 April 2026, up from 4.9%)
Late payment interest: 9.6% per year if repayments are overdue (7.6% if you set up an instalment plan)
Rates and thresholds are set by the NZ Government and may change — verify at ird.govt.nz
Interest-Free While in NZ
Since 2006, NZ student loans have been interest-free for New Zealand-based borrowers. This means:
- You borrow $30,000 during your degree
- 5 years after graduating, you’ve repaid $15,000 (automatically through PAYE)
- Your balance is $15,000 — not $15,000 plus years of interest
The practical effect: the repayment threshold and automatic deductions mean most New Zealanders repay their student loan within 8–12 years of graduating without needing to think about it.
5.6% Interest When Living Overseas
If you become an overseas-based borrower (you are in New Zealand for 31 days or less in a 184-day period), IRD applies an annual interest rate of 5.6% per annum to your outstanding balance (increased from 4.9% from 1 April 2026).
The interest accrues daily and is added to your balance annually.
Example:
- Outstanding balance: $20,000
- Year 1 interest (at 5.6%): $1,120
- Balance after year 1 (no repayments): $21,120
- Year 2 interest: $1,182.72
- Balance after year 2: $22,302.72
If you’re overseas for several years without making repayments, the balance grows. This is why many New Zealanders living overseas who have neglected their student loan return to find a much larger balance than expected.
Overseas-Based Repayment Obligations
When you’re overseas, you’re required to make repayments directly to IRD on a fixed repayment schedule (not percentage-based as in NZ). The amount required depends on your loan balance:
| Loan balance | Amount by 30 September | Total by 31 March |
|---|---|---|
| Under $1,000 | Half your balance | The remaining half |
| $1,000–$15,000 | $500 | $1,000 |
| $15,000–$30,000 | $1,000 | $2,000 |
| $30,000–$45,000 | $1,500 | $3,000 |
| $45,000–$60,000 | $2,000 | $4,000 |
| Over $60,000 | $2,500 | $5,000 |
IRD sends an assessment notice each year with your minimum amounts (IRD: repaying when I live overseas).
You must also notify IRD that you’re overseas-based within a specific timeframe. Failure to do so and to make required repayments attracts late payment interest.
Returning to NZ
If you return to New Zealand and re-establish NZ-based residency:
- Interest stops accruing
- Your loan reverts to interest-free status
- Repayments switch back to the PAYE-based system
Voluntary Repayments
You can make voluntary repayments to IRD at any time — and this directly reduces your balance and the time to repay. There’s no penalty for early repayment.
