NZ Student Loan Repayment Explained (2026)

If you went through a NZ university, polytech or PTE in the last 20 years, there's a decent chance you still have a student loan. The IRD holds around $16 billion of NZ student loan debt across roughly 700,000 borrowers, and the rules around repayment are weirder than most Kiwis realise.

Here's how it actually works in 2026 — and the decisions worth making.

The basics (NZ-based borrowers)

If you live in New Zealand and earn over the repayment threshold, IRD takes student loan repayments automatically out of your pay.

• Repayment rate: 12% of every dollar you earn above the threshold.
• Threshold (2026): $24,128/year, or about $464/week.
• Interest: Interest-free while you live in NZ. (Yes, really — and this hasn't changed since 2006.)

Example: You earn $65,000/year.

• Income above threshold: $65,000 − $24,128 = $40,872
• Annual repayment: 12% × $40,872 = $4,904.64
• Roughly $94/week deducted from your pay

This is on top of PAYE tax and ACC. Your payslip should show it as a separate "SLCIR" or "SL" line.

The overseas-based borrower trap

The rules change the moment you spend more than 183 days outside NZ in a 12-month window.

• You become an overseas-based borrower (OBB).
• Interest starts accruing on the full loan balance. The 2026 OBB rate is around 3.9% (varies by year — IRD sets it).
• You owe fixed repayments based on loan size, not income — even if you're unemployed. As of 2026 the brackets start around $1,000/year for sub-$15k loans and step up to $5,000+/year for $60k+ loans.
• Miss two consecutive payments and you can be hit with late-payment interest, default listings, and (in worst-case scenarios) arrest at the NZ border under the 2014 amendment.

If you're heading overseas with a student loan, two things to do before you go:

1. Set up auto-payments via myIR from a Wise or NZ bank account that you'll keep funded.
2. Consider a lump-sum voluntary payment to drop into a lower repayment bracket before the OBB status kicks in.

Voluntary repayments: do they make sense?

Because the loan is interest-free for NZ-based borrowers, voluntary repayments don't save you interest. So why would you pay it down faster?

Three legit reasons:

1. You're moving overseas soon

Pay it down now while it's interest-free. Every dollar paid before you leave is a dollar that won't accrue ~3.9% offshore interest. This is the biggest single lever most Kiwis miss.

2. The 12% deduction is killing your cash flow

If 12% of every dollar above $24k is more than you can spare, paying down the principal reduces… nothing. The 12% rate is fixed by income, not by balance. So paying it off faster doesn't lower the deduction — it just clears it sooner. Only useful if you're close to the finish line.

3. You want it gone for psychological reasons

Fair. Some people sleep better knowing it's clear. Just be aware the opportunity cost is real: $10,000 paid to IRD is $10,000 not in your KiwiSaver, emergency fund, or first-home deposit.

What to do instead (most cases)

For most NZ-based borrowers under 40, the priority order is:

1. High-interest debt first (credit cards, BNPL, anything over 5%) — see paying off credit card debt in NZ.
2. Emergency fund — 3 months of essentials. See building an emergency fund in NZ.
3. KiwiSaver to at least 3% — capture the full employer match. See KiwiSaver tips for 2026.
4. First-home deposit if relevant — see saving for a first home in NZ.
5. Then voluntary student loan repayments, if you have spare cash and want it gone.

The 12% deduction comes off automatically. Don't let it stop you from compounding other money in higher-leverage places.

The "should I just ignore it" question

Some Kiwis on lower incomes never cross the threshold and never make a repayment. The loan just sits there, interest-free, for life. The downsides:

• Mortgage applications ask about the balance — it counts as a liability for borrowing-capacity calculations.
• If you move overseas, the OBB rules kick in immediately, regardless of how long the loan has been dormant.
• The IRD can adjust your tax code if you forget to update them about income changes, leaving you with a debt at year-end.

So "ignoring it" is fine if your income stays low and you stay in NZ. It's not fine if either of those changes.

Common myths

"My student loan affects my credit score." Not really — IRD debts don't appear on credit reports unless they go to collections. A current, on-track student loan is essentially invisible to Centrix/illion.

"I can write it off after X years." No. There's no statute of limitations on NZ student loans. The only ways out are: pay it off, or die.

"Studying again pauses repayments." Studying full-time (12+ EFTS points/year) can drop you below the threshold via the studying-allowance route, but the loan keeps existing — and any income you do earn over the threshold is still deducted.

The bottom line

NZ student loans are the cheapest debt you'll ever carry — as long as you live in NZ. The 12% deduction is annoying but predictable. The big risks are the overseas trap (plan ahead) and treating the loan as a higher priority than KiwiSaver or emergency savings.
