Buying a home in New Zealand is exciting, but it can also feel overwhelming, especially when deciding whether to use a mortgage broker or go direct to a bank. The right choice can impact how quickly you are approved, the interest rate you get, and even the flexibility of your loan.
In this guide, we explain the pros and cons of both options, share insights from the Auckland mortgage broker market, and help you decide which path suits your situation whether you are a first home buyer, refinancing, or investing in property.
What is a Mortgage Broker?
A mortgage broker, also called a mortgage adviser in New Zealand, is a qualified professional who connects borrowers with lenders. Instead of offering loans from just one bank, an Auckland mortgage broker has access to multiple lenders, including ANZ, ASB, BNZ, Westpac, and specialist non-bank providers.
They assess your financial situation, compare interest rates and loan products, and recommend options that suit your needs. This can be especially valuable for first home buyers, those seeking home loan pre-approval, or borrowers with unique circumstances such as self-employment or lower deposits.
Most mortgage brokers do not charge clients directly. The mortgage broker cost is typically covered by the lender through a commission once the loan is approved and settled.
What Does Going Direct to a Bank Mean?
Going direct to a bank means working with a bank’s own mortgage specialist to arrange your home loan. This could be at ANZ, ASB, BNZ, Westpac, or another New Zealand bank. Unlike a mortgage broker, the bank’s adviser can only offer you their own products and interest rates.
This can work well if you already have a strong relationship with your bank, especially if you are a first home buyer mortgage NZ customer who may qualify for package deals, fee waivers, or special rates. However, the choice is limited compared to using a broker who has access to multiple lenders.
Mortgage Broker vs Bank — Key Differences
Choosing between a mortgage broker or direct to a bank comes down to understanding the differences in service, flexibility, and lender access.
| Feature | Mortgage Broker | Direct to Bank |
| Lender Access | Multiple lenders including ANZ, ASB, BNZ, Westpac, and non-bank providers | One bank only |
| Product Range | Wide range including fixed vs floating rate, offset, revolving credit | Only the bank’s own products |

| Cost to You | Usually free (lender pays commission) | Free |

How a Mortgage Broker Differs from a Salesman in a Bank
A mortgage broker acts as your advocate in the home loan process, whereas a bank’s salesperson is focused on meeting their bank’s lending targets. The broker’s role is to find you the best possible fit across multiple lenders and to assist with everything from home loan pre-approval to KiwiSaver first home withdrawal advice.
In contrast, a bank’s salesperson is limited to the bank’s own mortgage products, which can be a drawback if you need flexibility, are considering mortgage refinancing, or want to compare fixed vs floating rate options across the market.

- Do I want to compare interest rates and features from multiple lenders?

- Am I a first home buyer who needs guidance on KiwiSaver first home withdrawal or fixed vs floating rate options?
