Mortgage broker vs bank in NZ: which is better for you?

16 Oct 2026

In a mortgage broker vs bank comparison, the main difference is who you get advice from. A bank can only offer you its own loans, while a mortgage adviser can compare several lenders and apply to the one that fits you. Their advice is usually free to you, because the lender pays the adviser. Going direct to your bank can still make sense for a simple loan.

I’m a mortgage adviser, so I have an obvious interest here. I’ve tried to be fair about where a bank is the better choice. Lender policies and incentives change, so check the current position.

Mortgage broker vs bank in New Zealand

People often ask me whether they should just ask their own bank. It’s a fair question, and the answer isn’t always “use a broker”.

I’m Auckland-based and work with clients across NZ, so here is how I see the mortgage broker vs bank question, side by side.

Side by side

Mortgage broker vs bank: the comparison

The table is a summary. It doesn’t mean every adviser is better than every bank, and plenty of bank staff are very good. What’s different is the structure: a bank person can only offer you the bank’s loans.

Cost

Mortgage broker vs bank: how each gets paid

New Zealand advisers are mostly paid by the lender when your loan settles. You typically don’t pay a fee for the advice. Two things I want you to know about:

  • Commission exists. It can be a reason an adviser leans one way, which is why disclosure matters. Mine is in the Disclosure Statement.
  • Clawback exists. If you leave the lender early, some commission can be clawed back from the adviser. The same goes for cashback, which banks can claw back from you, often over 3–4 years. Ask before you move.

The honest test is simple: ask your adviser why they picked this lender, and what the alternatives were.

Send me your current loan or your offer to buy and I’ll tell you honestly whether going direct or using an adviser makes sense.

Rates

Will a mortgage broker get you a better rate?

Not automatically. Advertised “special” rates are available to everyone, and the banks update them daily. A broker’s edge is in comparing the whole loan, not just the rate: cashback, fees, how the loan splits, whether you can offset, and how the lender treats your income. My guide to comparing home loan rates covers what to look at beyond the headline number.

Where I add the most is when your situation isn’t simple. Self-employed, a low deposit, a few properties, or a past credit blip can all change which lender is right. Policies differ and are hard to see from the outside.

Declines

Mortgage broker vs bank if you’ve been declined

A decline from one bank doesn’t mean you can’t borrow. It often means your situation doesn’t fit that bank’s policy. Debt-to-income limits apply to banks but not non-banks, so a non-bank may suit you for a period. I wrote about that in what to do if your home loan is declined.

When direct works

When going direct to the bank makes sense

  • Your loan is simple: stable employment, a good deposit, and no unusual circumstances.
  • You’ve got a long relationship with a bank and you’re happy with its service.
  • You just want to refix with the same bank and you’ve already compared.

Even then, I’d get a second view before signing. Our guide to choosing the best bank shows you what to compare. If you’re looking for a local adviser, I’m a mortgage broker in Auckland and work with people around the country.

Questions

Common questions

Is a mortgage broker cheaper than going to the bank?
A broker’s advice is usually free to you, because the lender pays them. The rate you get depends on the lender and your situation, not on whether you went through a broker, so compare the total cost of the loan.
How do mortgage brokers get paid in NZ?
Mostly by commission from the lender when your loan settles. That commission can be clawed back if you leave the lender early, and any fees or commission are disclosed in the adviser’s disclosure statement.
Should I go to my own bank first?
It’s worth a call if you have a long relationship with your bank and a simple loan. But get a second view before you sign, because your bank can only offer you its own products.
What if my bank has declined me?
A decline from one bank doesn’t mean every lender will say no. An adviser can check other banks and non-banks whose policies suit your situation better.
