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, 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 begin automatically through the tax (PAYE) system once your income exceeds $22,828/year, 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 move overseas for more than 6 months, interest charges of ~3% per year apply.
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 ~$253/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
Repayments begin through PAYE once your income from all sources exceeds $22,828 per year (2026 threshold — confirmed annually by IRD).
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 income above the $22,828 threshold
| Annual Income | Income Above Threshold | Annual Repayment | Weekly Repayment |
|---|---|---|---|
| $30,000 | $7,172 | $861 | $16.56 |
| $50,000 | $27,172 | $3,261 | $62.71 |
| $70,000 | $47,172 | $5,661 | $108.87 |
| $90,000 | $67,172 | $8,061 | $154.96 |
| $120,000 | $97,172 | $11,661 | $224.25 |
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 | ~9–10 years |
Voluntary extra repayments reduce the balance and time to pay off. IRD accepts voluntary repayments at any time through myIR or direct bank payment to your loan account.
Going Overseas
If you move overseas for more than 6 months in a 12-month period, your student loan becomes interest-bearing:
| Overseas Duration | Interest Rate | Result |
|---|---|---|
| Under 6 months | 0% | Loan stays interest-free |
| 6+ months | ~3% per year | Loan grows annually |
You must also make overseas repayments — IRD sets a minimum repayment based on your loan balance rather than income (since they can’t access your foreign payslip).
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 at approximately:
- Loan under $15,000: $1,000/year minimum
- Loan $15,000–$30,000: $2,000/year minimum
- Loan $30,000–$45,000: $3,000/year minimum
- Loan over $45,000: Larger set amount
(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 — any amount above the standard deduction; go via myIR
- 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 — IRD accepts lump-sum repayments at any time. You can pay via myIR or direct bank transfer to your student loan account (your IRD number is the account reference).
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 $22,828/year, no repayments are required — the system automatically adjusts. If you’re struggling, contact IRD.
