Why Use a Mortgage Broker? (And What It Actually Costs)
When you walk into a bank for a home loan, you're getting one lender's products, assessed by that lender's credit team, at that lender's rates. When you work with a mortgage broker, you're getting access to multiple lenders — typically 10–20 or more — with an expert in your corner who knows how to present your application in the strongest possible light.
For most New Zealanders, a mortgage is the largest financial commitment of their life. Getting the right structure and the best available rate can save tens of thousands of dollars over the life of a loan. Yet many buyers still go directly to their bank out of habit or because they don't fully understand what a broker does. Let's change that.
What Does a Mortgage Broker Actually Do?
A mortgage broker (called a mortgage adviser in New Zealand) acts as your representative throughout the lending process. Here's what that looks like in practice:
- Assessment: They review your financial situation — income, debts, credit history, deposit, goals — and advise on how much you can realistically borrow and which lenders are most likely to approve you.
- Comparison: They compare rates, loan features, and approval likelihood across their panel of lenders. This includes main banks like ANZ, BNZ, Westpac, ASB, and Kiwibank, plus non-bank lenders for clients who don't fit the standard mould.
- Negotiation: Brokers often have access to rates that aren't advertised to the public, and can negotiate cash contributions (where the bank gives you cash back at settlement — often $2,000–$4,000) on your behalf.
- Application management: They prepare and submit your application, ensuring all the documentation is correct the first time. A strong application reduces the chance of delays or declines.
- Ongoing support: A good broker doesn't disappear at settlement. They'll check in when your fixed term is up, help you refix or refinance, and be there when your circumstances change.
What Does It Cost?
Here's the part that surprises most people: using a mortgage broker is free for the client in the vast majority of cases. Brokers are paid a commission by the lender when your loan settles — typically around 0.65%–0.85% of the loan amount, plus a small trail commission. You don't pay this; the lender does.
This commission structure is fully disclosed under New Zealand's financial advice regulations. Your broker is required to act in your best interests and to disclose any potential conflicts. If a broker charges you a fee (which some do for complex cases), they must tell you upfront.
So the question isn't whether you can afford a broker — it's whether you can afford not to use one.
Can a Broker Get You a Better Rate Than Going Direct?
Often, yes. Brokers have visibility across the market that individual borrowers don't. They know which banks are hungry for new business, which lenders are offering unadvertised specials, and which ones are more likely to approve your specific situation. A broker can also leverage the collective volume of their client base to negotiate better terms than you'd get as an individual.
Cash contributions are a good example. Banks regularly offer $2,000–$5,000 cash back to clients who move their loan to them at refinancing — but these offers aren't always publicly advertised. A broker will know what's available and factor it into the comparison.
When Should You Use a Mortgage Broker?
The honest answer: almost always. But a broker is particularly valuable when:
- You're a first home buyer navigating KiwiSaver, First Home Grant, and low-deposit options for the first time
- You're self-employed or have complex income (commissions, multiple jobs, rental income)
- You've had credit issues in the past
- You're looking to invest in property and need to structure things correctly
- You're approaching refixing and want to know if a better deal exists elsewhere
- You've been declined by a bank and want to understand your options
