Mortgage Broker vs Bank in NZ: Which Is Right for You?

Use a mortgage broker when you want your loan compared across lenders — a broker puts your application in front of a panel of banks and specialist funders and is paid by the lender, not by you. Go direct to a bank when your situation is simple, you already know that bank will approve you, and you are comfortable negotiating and checking the wider market yourself. The loan itself is the same money. What changes is how many lenders ever see your file, and who is working for whom.
What a bank does
A bank can only offer its own products, its own rates, and its own lending policy. That is not a flaw — if your income is a salary, your deposit is 20% or more, and the property is standard, your own bank may approve you quickly and its existing-customer offer may be competitive. But the banker cannot tell you another lender would have said yes on better terms, or would have counted your income differently. They are not allowed to sell what they do not have.
What a mortgage broker does
- Compares your application across 16+ lenders — main banks and specialist funders — instead of one
- Matches the file to policy: how each lender counts overtime, bonuses, self-employed income, boarders, and rental income differs, and that difference decides approvals
- Negotiates rate, cash contribution, and structure with more than one lender in play
- Runs the paperwork, valuation, and conditions through to settlement, and reviews the loan again before each fixed term ends
- Costs you nothing upfront: the lender pays a commission when the loan settles, and that commission has to be disclosed to you
Where it actually matters
The gap shows up when the file is not straightforward. Self-employed income, a deposit under 20%, a property a bank does not like, existing investment lending at the wrong bank, or a decline you do not understand — each lender reads those differently. It also matters at refinance time: a broker prices your own bank's retention offer against the market, so staying becomes a decision instead of a default. On a plain salary-and-20%-deposit purchase, be honest with yourself about how much shopping you will really do alone. Most people ask one bank. That is the comparison most broker clients are actually avoiding.
What a broker cannot do
A broker cannot guarantee an approval, a rate, or a cash contribution. We cannot make a lender count income it will not count. What we can do is send the file to the lenders most likely to say yes first, tell you plainly when the answer is no and why, and keep your own bank honest with a real alternative.
