Our verdict

BNZ is a bank you deal with directly, and its 4.89% home loan rate sits close to what the market median of 4.49% looks like. It suits New Zealand borrowers who want one bank for a purchase, a remortgage, a first home or a rental, and who value phone support over shopping many lenders.

Pros and cons

Pros

  • Fixed periods of 0.5 years let you plan ahead without waiting for a long tie in
  • One lender covers purchase, remortgage, first time buyer and buy to let needs
  • It lends directly as Bank of New Zealand, so you deal with the bank rather than a broker
  • Support runs on phone

Cons

  • The 4.89% starting rate is not the cheapest on the market, whose median initial rate is 4.49%
  • A fixed period of 0.5 years is short, so your rate can be repriced sooner than with longer deals
  • personal is the only loan type listed

Who it suits

  • New Zealand buyers taking a first home loan with a bank rather than a broker
  • Existing homeowners switching lender and pricing a remortgage
  • Property investors buying to let alongside personal borrowing

Who should look elsewhere

  • Borrowers chasing the lowest initial rate, where Sofkredit lists rates of 8% to 14%
  • Shoppers wanting a long fixed period, since Creditilia ES starts at 4% with different terms

Who runs it

BNZ is Bank of New Zealand, a direct lender based in New Zealand and founded in 1861. Because it lends directly, the rate and terms are set by the bank rather than routed through a broker, which can shorten the path from application to a decision. Help runs on phone, so anyone with an unusual application can talk it through with the bank directly. Together these point to a straightforward, single counterparty for a home loan.

Frequently asked questions

What rate does BNZ start at?+

The advertised initial rate is 4.89%. For context, the median initial rate across the mortgage ranking is 4.49%, so BNZ sits slightly above the middle of the market. Rates move, so check the current figure with the bank.

How long is the interest rate fixed for?+

The fixed period is 0.5 years, which is a short tie in compared with the mortgage ranking median of 10 years. After that period your rate can be reset, so plan for a possible change if your plans stretch beyond it.

What can I use a BNZ loan for?+

The listed purposes cover purchase, remortgage, first time buyer and buy to let. That means the same bank can handle a home purchase and a switch of lender later. The loan type recorded is personal.

Who am I dealing with?+

BNZ is Bank of New Zealand, a direct lender based in New Zealand, founded in 1861. Dealing directly means the rate and terms come straight from the bank, with no broker layer between you and the application.

How do I get help with the loan?+

Support runs on phone, so questions about a rate or application go through a phone call. A lender that answers by phone can be useful if your circumstances are unusual or your application needs explaining.

Is BNZ the cheapest option?+

Not on the advertised starting rate. The 4.89% rate here compares with a mortgage ranking median of 4.49% and an upper quartile of 6.75%, so cheaper options exist in the market. The short 0.5 year fixed period is also worth weighing.

Does BNZ lend outside New Zealand?+

The lender is based in New Zealand and is a direct lender, so its home loans are aimed at the New Zealand market. Borrowers in other markets would be comparing against lenders local to them rather than this bank.
