What Happens to Your Student Loan If You Move Overseas?

Your NZ student loan overseas stays interest-free as long as you remain “New Zealand-based” — present in NZ for at least 32 days within any 184-day period. Spend 31 days or fewer in NZ during that window, and you become “overseas-based”: interest starts accruing from the day after you first left, and your repayments switch from income-based to a fixed amount based on your loan balance.

The 32-Day Rule, Stated as Plainly as Possible

If you are present in New Zealand for 32 days or more within any rolling 184 day period, you remain a New Zealand based borrower — interest-free, income based repayments, business as usual.  Spend 31 days or fewer in NZ during that same 184-day window, and Inland Revenue reclassifies you as overseas-based from the day after you first departed.

Two details that matter more than the headline number:

• The 32 days don’t need to be consecutive — they can be made up of several separate visits back to New Zealand within the 184-day window.
• You cannot be overseas for more than 152 consecutive days at any one time, regardless of how the rest of your 184-day window looks — a single unbroken absence longer than that breaks New Zealand-based status on its own.

A Real Worked Example Of Student Loan Overseas— How the Count Actually Plays Out

Rule statements alone are where most people misjudge their own situation — a concrete timeline makes the mechanics far clearer.

Meet Priya, who leaves New Zealand for an extended working holiday:

Event	Days	Running effect
Priya departs NZ for Australia	Day 0	184-day clock starts the next day
Works in Australia for 92 days	Days 1–92	Still within the window
Returns to NZ for a visit	18 days in NZ	Contributes toward the 32-day requirement
Departs again — Europe (Croatia, Austria, Hungary)	25 days	Still tracking
Continues to Italy, France, Netherlands, Germany	33 days	Total overseas time climbing
Returns to NZ again, stays with family	16 days	18 + 16 = 34 days total in NZ — over the 32-day minimum
184 days have now elapsed since her first departure	—	Priya remains New Zealand-based, since she accumulated 34 days in NZ (spread across two visits) within the 184-day window

What would have broken this: if Priya’s first NZ visit had been only 10 days instead of 18, her total in-NZ time (10 + 16 = 26 days) would have fallen short of 32 — reclassifying her as overseas-based, with interest backdated to the day after her very first departure, even though most of her actual time was spent bouncing between multiple countries, not staying away in one place.

 What Actually Changes Once You’re Overseas-Based

	New Zealand-based	Overseas-based
Interest	None — fully interest-free	Charged from the day after you first left, at the current overseas rate
Repayment basis	12% of income above $24,128/year	Fixed amount based on your loan balance, regardless of income
Repayment dates	Deducted automatically through PAYE each payday	Two fixed annual dates: 30 September and 31 March
Who initiates payment	Your employer, automatically	You — payments are no longer taken from wages; you must arrange payment yourself
Repayment flexibility	N/A (automatic)	You can pay fortnightly or monthly instead of just the two annual dates, which can reduce total interest paid

The repayment-basis change is the part most people don’t expect: even if you’re not working at all while overseas, or working in a low-paying job, you can still owe a fixed repayment amount based purely on how large your loan balance is — income becomes irrelevant to the calculation once you’re reclassified.

Coming Back to New Zealand — The Return Rules Are Slightly Different

If you’ve become overseas-based and later return, the thresholds for switching back aren’t simply the mirror image of the 32-day rule:

• Back in NZ for at least 152 of the next 183 days → you become New Zealand-based again
• Out of NZ for at least 32 of those 183 days → you remain overseas-based
• Somewhere in between (more than 152 days back, but the visit ends before 183 days) → your status may be genuinely unclear, and IRD recommends contacting them directly to confirm

This asymmetry — 32 days to lose NZ-based status, but 152 days to regain it — surprises people who assume the rule works identically in both directions.

Can You Avoid Interest Even While Genuinely Overseas?

Yes, in specific circumstances. Inland Revenue can grant an exemption to the standard day-count rule if you meet certain conditions and provide supporting evidence — common exemption categories include full-time study overseas and certain approved work or volunteering situations. If granted, you continue receiving the full interest write-off for the exempted period, even though you’d otherwise fail the day-count test.

Separately, a “temporary repayment suspension” lets you pause compulsory repayments while overseas — but interest continues to accrue during a suspension at the standard overseas rate, so it reduces your immediate payment burden without reducing what you ultimately owe. IRD needs to be notified either before you leave, or within 6 months of leaving, to arrange this.

Practical Steps Before You Leave New Zealand

1. Register for myIR if you haven’t already, and use the “Overseas travel calculator” tool built into the platform to model your specific planned trip against the 32-day rule before you book anything.
2. Notify IRD of your travel plans, particularly if you intend to apply for a suspension or exemption.
3. Nominate someone in New Zealand who can manage loan correspondence and payments on your behalf while you’re away.
4. Set up a reliable international payment method in advance, since overseas-based repayments are no longer automatically deducted from wages.
5. Keep records of your own travel dates independently — don’t rely solely on memory or a single phone conversation with IRD for a borderline case; get anything important confirmed in writing.
