How it works

Eligible systems

You can use the loan for solar power, small-scale hydro, wind energy or geothermal resources. The system you buy has to be for sale to the general public, have at least a 10-year manufacturer’s warranty and be supplied and installed by a company that’s a member of the Sustainable Electricity Association of New Zealand (SEANZ). The Sustainable Energy Loan has to be taken out at either the time the system is installed, or when you get an agreement for installation. The loan is not available for commercial business purposes.

Structure

The Sustainable Energy Loan is a variable rate home loan. The minimum loan term is seven years, the maximum term is 10 years. It's not available with offset mortgage or revolving credit home loans.

Topping up your home loan

If you already have a Kiwibank Home Loan, you may be able to top it up to pay for an eligible sustainable energy system. We’ll waive the home loan top-up fee.

Switching your loan

If you’re switching your home loan to Kiwibank and need additional lending to buy an eligible sustainable energy system, part of your loan will count as the Sustainable Energy Loan and our contributions will be added to that.

Building a new home

If you’re building a new house that has a sustainable energy system included in the cost of the property, part of your loan will count as the Sustainable Energy Loan and our contributions will be added to that.
