One of the first decisions when getting a mortgage in New Zealand is whether to go directly to a bank or use a mortgage broker. Both routes can get you a mortgage — but the experience, outcome, and effort required differ significantly.
What Does a Mortgage Broker Do?
A mortgage broker acts as an intermediary between you and lenders. They:
- Assess your financial situation and borrowing capacity
- Research which lenders are most likely to approve your application at the best rate
- Prepare and submit your application on your behalf
- Manage the paperwork and chase the bank for you
- Negotiate the rate and terms with the lender
- Provide advice throughout the process
A broker typically has access to 10–20+ lenders, including the major banks and a range of non-bank lenders — giving you far more options than approaching one bank directly.
How Are Mortgage Brokers Paid?
The most important thing to understand: you don’t pay a broker’s fee directly. Brokers are paid a commission by the lender when your loan settles.
Typical commission: approximately 0.55%–0.75% of the loan amount (upfront) plus a trail commission of ~0.15%/year while the loan is active.
Does this create a conflict of interest? The commission is roughly similar across lenders, so brokers generally don’t have a strong financial incentive to recommend one bank over another. However, you should be aware of the structure and can ask your broker to confirm they’re recommending the best option for you, not the highest commission.
Under the Financial Markets Conduct Act, NZ mortgage brokers are required to act in your best interests and disclose any material conflicts.
Broker vs Direct: The Comparison
| Feature | Mortgage Broker | Going Direct |
|---|---|---|
| Lenders accessed | 10–20+ | 1 |
| Rate competition | High — broker shops around | Low — bank offers one rate |
| Cost to you | Free (bank pays) | Free |
| Time and effort | Lower (broker manages process) | Higher (you manage everything) |
| Expertise | Specialist | General relationship manager |
| Non-standard situations | Better handled | Variable |
| Existing relationship benefit | You lose relationship benefit | Leverage with existing relationship |
| Cashback access | Yes (broker can access cashback from multiple lenders) | Only from that bank |
When to Use a Mortgage Broker
Use a broker when:
- You’re a first home buyer and don’t know the market well
- Your situation is complex (self-employed, variable income, multiple debt sources, non-standard employment)
- You’ve been declined by one bank and want to understand your options
- You want to compare multiple lenders without doing the legwork yourself
- You’re refinancing and want to know whether your current bank’s offer is competitive
- You don’t have time to manage multiple bank applications simultaneously
- You want to use the First Home Loan — brokers can help assess eligibility and submit the Kāinga Ora application alongside the mortgage
Go direct to a bank when:
- You have a long-standing relationship with one bank and consistently get preferential treatment (e.g., you’re a private banking customer)
- Your situation is very simple (large deposit, stable PAYE income, clean credit, no complexity)
- You’ve done thorough rate research and your existing bank is clearly the best option
- You’re refixing (not switching) and just want to renegotiate your rate — a quick call is usually sufficient
What a Good Broker Will Do
A good NZ mortgage broker will:
- Discuss your full financial situation (not just the headline numbers)
- Explain your borrowing capacity honestly — including limitations you may not want to hear
- Present multiple lender options with pros and cons, not just the one with the best rate
- Be transparent about their commission and any relationships with specific lenders
- Manage the entire application process, keeping you informed at each stage
- Be reachable — mortgage applications are time-sensitive
Warning signs of a poor broker:
- Recommends only one lender without explanation
- Doesn’t disclose how they’re paid
- Provides unrealistic borrowing estimates
- Disappears during the application process
- Pressures you to act quickly without full information
How to Find a Mortgage Broker in NZ
Look for:
- Authorised Financial Advisers (AFA) or Financial Advisers — regulated under the Financial Markets Conduct Act
- Members of NZFSG (New Zealand Financial Services Group) or Astute or independent advisers
- Brokers with strong Google/Trustpilot reviews and verifiable client references
- Brokers who specialise in your situation (first home buyers, investors, self-employed)
You can search the Financial Service Providers Register (FSPR) at fsp.govt.nz to confirm a broker is licensed to provide mortgage advice.
Can a Broker Get a Better Rate Than Going Direct?
Often, yes — for several reasons:
- Broker volume discounts: Brokers who send significant lending volume to a bank negotiate preferred rates for their clients not available to walk-in customers
- Competition pressure: When the broker is shopping your application across multiple lenders, each lender knows they’re competing — this encourages better offers
- Knowledge of lender policies: An experienced broker knows which bank has the most attractive current rate for your specific situation and LVR
That said, if you have an excellent relationship with your existing bank, they may match or beat any broker quote to retain your business.
