Loan styles, buyer support and calculator limits

Borrowers commonly split loans into fixed and floating portions. Revolving-credit and offset structures exist, and fixed terms are shorter than the full amortization period.

Common loan styles

  • Fixed-rate table mortgage
  • Floating-rate mortgage
  • Offset or revolving-credit home loan and split-loan structures

Government or structured support

  • Kāinga Ora First Home Loan can reduce the required deposit to 5% for eligible buyers, subject to lender and program criteria
  • Eligible KiwiSaver members may make a first-home withdrawal
  • The former First Home Grant closed in 2024 and must not be shown as current

What to verify locally

  • Allow split balances and multiple fixed-rate expiry dates
  • Treat KiwiSaver withdrawal as buyer funds, not a grant
  • Test First Home Loan eligibility separately from payment math
