New Zealand’s student loan scheme is one of the most borrower-friendly systems in the world: it is interest-free while you remain in New Zealand (though IRD charges a $40 administration fee if your balance is $20 or more at 31 March), automatic repayments are collected through the tax system, and there is no penalty for having a large balance as long as you stay. Understanding how it works helps you plan your financial life around it.
NZ student loans are interest-free while you live in New Zealand. Repayments are deducted automatically through the tax (PAYE) system once your main job's pay exceeds $24,128/year ($464/week), at a rate of 12% on income above that threshold. A $40,000 student loan on a $70,000 salary takes approximately 5–6 years to repay at the standard rate. If you become overseas-based (in NZ 31 days or less in a 184-day period), interest applies (IRD's rate is 5.6% a year from 1 April 2026; it is set each tax year).
How Student Loans Work in NZ
What You Can Borrow
| Component | Amount | Notes |
|---|---|---|
| Tuition fees | Actual fees | Paid directly to your tertiary institution |
| Living costs | Up to $333/week | Deposited into your bank account weekly |
| Course-related costs | Up to ~$1,000/year | Equipment, textbooks, etc. |
You apply through StudyLink for each year of study. Loan amounts are determined based on your course and enrolment status (full-time/part-time).
Interest Rate While in NZ
0% — NZ’s student loan scheme charges no interest while you remain in New Zealand. This is globally unusual and means your loan balance only decreases with repayments — it never grows unless you’re overseas.
Student Loan Repayment
When Repayments Start
Repayment deductions from your main job’s pay start once that pay exceeds $24,128 a year ($464 a week). The threshold doesn’t apply to a secondary job: pay from a secondary job has repayments deducted from the first dollar, because the threshold has already been used for your main job (IRD: repaying when I earn salary or wages). Other income, such as self-employment, is squared up at the end of the year.
If you’re employed (PAYE), your employer deducts your student loan repayment from your pay automatically. Use the tax code “SL” suffix: your tax code becomes M SL instead of M.
Repayment Rate
12% of main-job pay above the $24,128 threshold
| Annual Income | Income Above Threshold | Annual Repayment | Weekly Repayment |
|---|---|---|---|
| $30,000 | $5,872 | $705 | $13.55 |
| $50,000 | $25,872 | $3,105 | $59.70 |
| $70,000 | $45,872 | $5,505 | $105.86 |
| $90,000 | $65,872 | $7,905 | $152.01 |
| $120,000 | $95,872 | $11,505 | $221.24 |
How Long Does It Take to Repay?
| Student Loan Balance | Income | Years to Repay (Standard Rate) |
|---|---|---|
| $20,000 | $55,000 | ~5 years |
| $40,000 | $55,000 | ~10 years |
| $40,000 | $80,000 | ~5–6 years |
| $60,000 | $70,000 | ~10–12 years |
| $80,000 | $90,000 | ~10–11 years |
Voluntary extra repayments reduce the balance and time to pay off. You can make one-off payments to IRD when you can, or ask your employer to make extra repayments from your pay on top of the standard deductions (IRD: extra repayments).
Going Overseas
If you are in New Zealand for 31 days or less in a 184-day period, you are overseas-based and your student loan becomes interest-bearing:
| Overseas Duration | Interest Rate | Result |
|---|---|---|
| In NZ 32 days or more in a 184-day period | 0% | Loan stays interest-free |
| In NZ 31 days or less in a 184-day period | 5.6% a year (IRD’s rate from 1 April 2026, set each tax year) | Interest is added from the day after you left NZ |
You must also make overseas repayments yourself: they are based on your loan balance rather than your income, and are generally due by 30 September and 31 March (IRD: repaying when I live overseas).
If you’re planning to live overseas, make voluntary repayments before you go and contact IRD to set up an overseas repayment arrangement.
Repayment amounts are publicly set by IRD based on your loan balance at 31 March each year:
- Loan $1,000–$15,000: $1,000/year minimum
- Loan $15,001–$30,000: $2,000/year minimum
- Loan $30,001–$45,000: $3,000/year minimum
- Loan $45,001–$60,000: $4,000/year minimum
- Loan over $60,000: $5,000/year minimum
(Exact thresholds confirmed by IRD annually — verify at ird.govt.nz)
Strategies for Paying Off Faster
- Use the SL tax code on all employment — this ensures standard deductions happen automatically from all income
- Make voluntary payments: one-off payments to IRD, or extra deductions your employer takes from your pay
- Put bonuses and pay increases toward the loan — especially before you get used to spending the extra
- If going overseas — repay as much as possible before you leave to avoid interest compounding
Study Abroad and Course-Related Issues
- Studying overseas: Student loans are not available for overseas study in most cases
- Dropping out mid-year: If you withdraw from a course, you may have to repay some or all of the fees component to StudyLink; check your withdrawal date vs the “fee-free” refund period
Frequently Asked Questions
Can I repay my student loan in a lump sum?
Yes. You can make one-off payments to IRD whenever you can (IRD: extra repayments).
Does my student loan affect my credit score?
Not directly — NZ student loans do not appear on your credit file the same way consumer debt does. However, lenders consider student loan repayments as a deduction when assessing home loan serviceability. Your take-home pay after student loan repayments is what matters for mortgage applications.
What if I can’t afford repayments?
If you’re earning less than $24,128/year, no repayments are required — the system automatically adjusts. If you’re struggling, contact IRD.
