About our home loans and this calculator

This calculator is intended as a guide only and is not a quote or an offer of finance by BNZ.

Things you should know about our home loans

All home loans are subject to our lending criteria, terms and fees. Interest rates are subject to change. Some interest rates may require you to have a certain minimum equity in the property used as security, and for some rates a low equity interest rate premium rate may apply if you have a low loan to value ratio. An establishment fee of up to $400 may apply for personal lending (the fee may be different for non-personal lending).

We’ve had to make some assumptions to calculate your approximate repayments:

  1. There are no changes to the loan amount and you don’t borrow any extra on this loan.
  2. You don’t make any additional lump sum repayments or increase your regular repayments above the standard repayments (but you could choose to do this to reduce the term and interest charges, if your loan allows).
  3. You make all your repayments in full and on time.
  4. The interest rate remains the same for the term of your home loan. Note that in reality, interest rates are likely to change over time.
  5. The interest on your home loan is calculated daily and charged at the same frequency as you choose for repayments, over the term of your loan.
  6. Your repayment amounts are calculated on a “principal and interest” basis for the term of the loan.
  7. Actual amounts may vary slightly due to rounding.

Fly Buys points can only be earned on Fly Buys loans. Fly Buys terms and conditions apply. BNZ (and its related companies) do not guarantee the redemption of Fly Buys or that Fly Buys will continue to be offered for products or services provided by BNZ. Fly Buys collection and redemption rates can change without notice.
