Buying your first home in New Zealand is exciting, but the mortgage application process can feel overwhelming. From understanding your borrowing capacity to finalising your loan, knowing what to expect can make the journey smoother and less stressful. Here’s a step-by-step guide for first-time buyers.

1. Assess Your Financial Situation
Before applying for a mortgage, it’s crucial to understand your financial position:
- Income and expenses: Track your monthly income and expenses to see how much you can afford to repay.
- Savings: Most banks require a deposit, typically 10–20% of the property’s purchase price. First-home buyers may qualify for the KiwiSaver HomeStart grant or a first-home deposit scheme.
- Credit score: A healthy credit history increases your chances of loan approval and better interest rates.
2. Determine Your Borrowing Capacity
Your borrowing capacity is the maximum amount a bank will lend you. Factors that influence this include:
- Income and employment stability
- Existing debts (like student loans or credit cards)
- Living expenses
- Loan term and interest rates
Many banks offer online calculators to give you an estimate of what you can borrow.
3. Research Mortgage Options
In New Zealand, you can choose from different types of mortgages:
- Fixed-rate mortgage: The interest rate is locked in for a set period (e.g., 1–5 years). It provides certainty in repayments.
- Floating (or variable) rate mortgage: The interest rate can change over time, which could increase or decrease your payments.
- Split mortgage: Part of your loan is fixed and part is floating, offering a balance of security and flexibility.
Compare interest rates, fees, and features from multiple lenders to find the right fit.
4. Get Pre-Approval
Pre-approval is a conditional agreement from a lender on how much they may lend you. Benefits include:
- Knowing your budget before house hunting
- Showing sellers you are a serious buyer
- Speeding up the mortgage process once you find a property
To get pre-approval, you’ll need:
- Proof of income (payslips, tax returns)
- Bank statements
- ID documents (passport, driver’s license)
- Details of your savings and KiwiSaver contributions
5. Find a Property and Make an Offer
Once pre-approved, you can start looking for your dream home. When you find it:
- Make an offer to purchase
- Include any conditions, such as finance approval or building inspections
Once the offer is accepted, you’ll formally apply for your mortgage.
6. Submit Your Mortgage Application
After your offer is accepted, submit your mortgage application to your chosen lender. This involves:
- Completing a full application form
- Providing supporting documents (income, savings, identity)
- Property information from the sale agreement
Your bank will then assess your application, conduct a property valuation, and confirm your loan amount and terms.
7. Final Approval and Settlement
If your application is approved:
- Sign your mortgage documents
- Organize insurance (usually house and life insurance)
- Arrange settlement with your solicitor or conveyancer
On settlement day, the bank transfers the funds to the seller, and you officially become a homeowner.
8. Tips for First-Time Buyers
- Start saving early for your deposit and costs like legal fees and moving expenses.
- Check if you qualify for first-home grants or KiwiSaver benefits.
- Keep communication open with your lender—respond promptly to any requests.
- Consider talking to a mortgage broker—they can save you time and help you get better deals.
Buying your first home in New Zealand doesn’t have to be stressful. With the right preparation and understanding of the mortgage process, you’ll be steps closer to turning the key to your new home.
