Should You Pay Off Your Student Loan Early in New Zealand? 2026 Guide
New Zealand has one of the most borrower-friendly student loan systems in the world: no interest while you’re a NZ resident. That changes everything about whether paying extra is a good idea.
For most NZ residents, paying off your student loan early is a low priority. The loan is interest-free, so every extra dollar you pay off saves you nothing in interest. That money earns more invested or used to pay down high-interest debt. The exception: if you're planning to move overseas, where interest of ~3% p.a. applies immediately.
How NZ Student Loan Repayments Work
Automatic deductions via IRD
If you’re employed, your employer deducts student loan repayments automatically via PAYE — you don’t need to do anything. The rate is:
- 12% of income above $22,828/year (the repayment threshold)
- Applied to gross salary
Example: Salary of $65,000/year
- Income above threshold: $65,000 – $22,828 = $42,172
- Annual repayment: $42,172 × 12% = $5,061/year
- Monthly deduction: ~$422
Self-employed or on a schedule C
If you’re self-employed, you make student loan repayments through your income tax return. IRD calculates the amount based on your taxable income.
Average balance at graduation
The average student loan balance at graduation in New Zealand is approximately $20,000, though those completing postgraduate degrees, or who took longer, often have $30,000–$50,000 or more.
The Interest-Free Reality
Because your student loan is interest-free while you’re in New Zealand, paying extra voluntary repayments costs you the opportunity to earn a return elsewhere.
| Extra repayment of $5,000 | Effect |
|---|---|
| Student loan interest saved | $0 (0% loan) |
| If invested in index fund at 8% | ~$400/year in returns |
| If used to clear credit card debt at 21% | ~$1,050/year in interest avoided |
The opportunity cost is significant. Your student loan is your cheapest debt — possibly the cheapest debt you’ll ever have. Pay everything else first.
Debt priority order (for most NZ residents)
- High-interest debt: credit cards (21%), finance company loans (20–30%)
- Car loans / personal loans (12–16%)
- Bank personal loans (9–13%)
- Mortgage (~6–7%)
- Student loan (0%) — last
When Voluntary Repayments Make Sense
If you’re planning to move overseas
Once you leave New Zealand for more than 183 days in a 12-month period, your student loan starts accruing interest. The current overseas rate is approximately 3% p.a. as of 2026 (set annually by IRD based on their cost of borrowing).
If you’re planning an OE or permanent move:
- Make voluntary repayments before you leave to reduce the balance
- Contact IRD to set up overseas-based repayment obligations once you leave
- Failing to make repayments while overseas results in the interest compounding on a larger balance
Rule of thumb: If you’ll be overseas for 2+ years, clear as much as you can before departure. At 3% p.a. on $25,000, that’s $750/year in interest — not catastrophic, but avoidable.
If the loan causes psychological stress
Some people get genuine value from clearing a loan — even a 0% loan — because it reduces anxiety or simplifies finances. If the peace of mind has real value to you, that’s a legitimate reason to pay extra.
If you have excess cash with no better use
If you have no high-interest debt, a fully funded emergency fund, and maximum KiwiSaver contributions, and you still have excess cash above what you’d comfortably invest, clearing the student loan is a reasonable use of funds.
How to Make Voluntary Repayments
Through your MyIR account at ird.govt.nz:
- Log in to myIR
- Go to “Student loan”
- Select “Make a payment”
- Enter your amount and pay directly to IRD
You can also use direct credit to IRD’s bank account — the reference must be your IRD number.
Important: Voluntary repayments are generally non-refundable. Don’t overpay if you’re uncertain.
Current Student Loan Interest Rates (Overseas)
| Location | Interest rate |
|---|---|
| NZ resident | 0% |
| Overseas (2026) | ~3.0% p.a. |
The overseas rate is set each year. Check IRD’s website for the current rate.
IRD Student Loan Account — What You Can See
In myIR you can see:
- Current loan balance
- Payment history
- Estimated payoff date (based on current salary)
- How your automatic deductions are being applied
The estimated payoff date is useful for understanding how long the automatic 12% deduction will take to clear the loan at your current income.
Common Myths
“I should pay it off fast so it doesn’t hang over me.” A 0% debt that’s being automatically repaid requires no action from you. It’s not hanging over you — it’s just being processed.
“I’ll save money paying extra.” You won’t save interest on a 0% loan. Every dollar of extra repayment saves zero in interest cost.
“Lenders care about my student loan balance.” Lenders do factor your student loan repayment deduction into your disposable income assessment (it reduces your take-home pay). But the loan balance itself isn’t a negative for mortgage applications the way a credit card default would be.
Summary Decision Framework
| Situation | Recommended action |
|---|---|
| NZ resident, other debts above 8% | Pay other debts first |
| NZ resident, no other debts, invested | Let IRD deductions run |
| Planning to move overseas in 1–2 years | Pay extra to minimise interest exposure |
| Already overseas | Set up IRD overseas repayment plan |
| Excess cash, no better use | Voluntary repayments are fine |
