Using a Mortgage Broker NZ — How the Process Works

Using a mortgage broker can save time, get you a better rate, and navigate complex lending situations — but many borrowers don’t know what to expect from the process. This guide walks through exactly how working with a NZ mortgage broker works, from first contact to settlement.

Step 1: Initial Consultation (Free)

Most NZ mortgage brokers offer a free initial consultation — in person, by video call, or by phone. This is a discovery session where the broker learns about your situation and you assess whether they’re a good fit.

What the broker will ask:

What you’re trying to achieve (first home, investment, refinance)
Your income sources and employment situation
Your deposit or current equity
Your existing debts and liabilities
Your timeline
Any known challenges (self-employment, previous credit issues, etc.)

What you should ask the broker:

How many lenders do you have on your panel?
How are you paid? (Confirm commission structure)
What’s your experience with [my specific situation — first home/self-employed/investor]?
How do you communicate throughout the process?
What’s your typical turnaround from application to approval?

Step 2: Document Collection

Once you decide to proceed, the broker will request supporting documents to complete your application. Prepare to provide:

Income evidence:

Last 3 months’ payslips (PAYE employees)
Last 2 years’ financial statements and tax returns (self-employed/company directors)
Most recent IR3 return and Notice of Assessment

Bank statements:

Last 3–6 months’ statements for all personal accounts
Credit card and loan statements

Identity:

Passport or driver’s licence (photographic ID)
Proof of address (utility bill, bank statement)

Liabilities:

Statements for all loans: car loans, personal loans, student loan (if applicable)
Credit card statements (all cards, including zero balance)
BNPL (Afterpay, Laybuy) statements

Deposit/equity:

Savings account statements showing deposit build-up (or current account if refinancing)
KiwiSaver balance statement
Any gift documentation (if receiving a gifted deposit)

The broker compiles all of this into an application package. The goal is to submit a complete, well-presented application that minimises bank back-and-forth.

Step 3: Broker Assessment and Lender Selection

The broker analyses your situation and determines:

Your borrowing capacity — how much you can borrow based on income, DTI limits, and serviceability
Which lenders are most suitable — based on your situation, deposit, and any complexity
What rate you should target — based on current market and your profile
Any issues to address — e.g., a credit check that reveals an old default, or a bank statement that needs explaining

The broker may also identify pre-application fixes — actions you can take before submitting that will improve your application (closing a credit card, paying down a car loan, spending 3 months proving clean bank statements).

Step 4: Application Submission

The broker submits the application to one (or sometimes two) lenders on your behalf. A good application includes:

A cover letter explaining your situation (addressing any non-standard elements)
All supporting documents, clearly organised
The broker’s assessment of your borrowing capacity

You don’t need to do anything at this stage beyond being available to answer any follow-up questions from the broker.

Note: The broker submits to one primary lender at a time (not multiple simultaneously, which would result in multiple credit enquiries). If the primary lender declines or offers terms that aren’t competitive, the broker moves to the next option.

Step 5: Conditional Approval / Pre-Approval

The bank issues conditional approval (also called pre-approval) — confirming they’ll lend up to a specified amount, subject to conditions (typically: a suitable property at an acceptable valuation, no material change in financial circumstances).

Pre-approval is typically valid for 90 days. If you haven’t found a property within that time, the broker can usually extend or refresh the approval.

During the property search phase, the broker is available for advice on specific properties — particularly:

Whether the property type is acceptable to the bank
Whether the purchase price aligns with the pre-approval
Whether auction finance needs strengthening before bidding

Step 6: Formal Approval (Property-Specific)

Once you’ve found a property and had an offer accepted, the broker submits the property details to the bank for formal approval. The bank may require:

A registered valuation (the broker can arrange this)
Confirmation of the sale and purchase agreement terms
Any property-specific investigation (construction type, title issues, etc.)

The bank issues formal approval — the unconditional commitment to lend for this specific property.

Step 7: Settlement

Your solicitor handles the settlement mechanics — the broker’s role here is largely complete. However, a good broker will:

Confirm settlement is proceeding smoothly
Advise on your fixed/floating structure at settlement if you haven’t already decided
Be available if any last-minute issues arise

After Settlement: What Good Brokers Do

A relationship-focused broker stays in touch after settlement to:

Advise on refixing decisions when your fixed term expires
Alert you to rate changes or cashback opportunities
Help with future refinancing, investment property, or equity release

A broker who disappears after settlement misses most of their long-term value.

Questions to Ask Before Choosing a Broker

How many lenders are on your panel? (Fewer than 5 is limiting)
Are you licensed? (Must be registered as a Financial Adviser under FMCA)
How are you paid? (Should disclose commission; no charge to you directly)
Do you have experience with [my situation]?
Can you provide references from past clients?
How do you communicate? Phone, email, video call?
