Kiwibank offers its customers the “Kiwibank Offset Mortgage” (the Product). The Product allows a customer to elect that interest payable by them on a loan made by Kiwibank be calculated by offsetting the balance of the loan against the aggregate credit balances of certain nominated transaction and savings and investments bank accounts held either by that customer or by certain other eligible person(s). Interest is payable on the net notional balance of these combined accounts. The Product was previously only available only to individual customers. It will now be made available to business customers, including companies and trusts.
