New Zealand financial terms for the compulsory KiwiSaver and student loan era
National's compulsory KiwiSaver plan targets July 2028 implementation with rates rising to 12% combined by 2032. Overseas-based student loan borrowers face 5.6% annual interest the moment they pass 184 days abroad. Property investors regained full mortgage interest deductibility from 2025-26. These terms cover the rules that affect your paycheck, student debt, and rental income.
Compulsory KiwiSaver and the total remuneration ban
Once KiwiSaver becomes mandatory (target: July 2028), the opt-out option disappears. Combined contributions are planned to reach 12% (6% employee + 6% employer) by 2032. Finance Minister Nicola Willis signaled a ban on total remuneration packaging, meaning employers must pay their KiwiSaver match ON TOP of the advertised salary, not deducted from it.
Overseas student loan interest and repayment obligations
Leave NZ for 184+ consecutive days and your interest-free loan starts charging 5.6% per annum on the entire balance. Short return trips under 31 days do not reset the clock. Repayment suspension is available during genuine hardship but does not stop interest accruing. Late payment interest stacks on top of the standard 5.6% if you miss your annual assessment deadline.
Interest deductibility restoration
Residential rental mortgage interest is fully deductible again from the 2025-26 tax year (phased: 50% in 2023-24, 80% in 2024-25, 100% from 2025-26). This saves landlords with $30,000/year in mortgage interest approximately $9,900/year at the 33% tax rate.
