How it works
If you live in New Zealand, your employer takes 12% of every dollar you earn over the threshold of $24,128 a year (worked out each pay period), and your loan is interest-free. Self-employed income is repaid through your end-of-year tax. Living overseas? Different rules and interest apply.
For NZ-based borrowers, tax code M SL. Rules last checked October 2026. Not legal, tax or financial advice. 🔒 Everything stays on your device.
