Maternity & Parental Leave: How It Affects Your Mortgage (And How to Get Approved)

A quick heads-up before we dive in: This article is strictly for general informational purposes and does not constitute financial, legal, or tax advice. Every situation is entirely unique, and bank lending policies change frequently. Before making any decisions about your property journey, it is highly recommended that you seek independent advice from a qualified financial adviser.

Starting a family is one of the most exciting chapters of your life, and it is usually the exact moment you decide you need to buy a bigger house or finally get onto the property ladder. But applying for a mortgage while you are pregnant, or actively on leave with a newborn, adds a unique layer of complexity to your bank application.

A quick note on terminology: While many people still search for maternity or paternity leave (hence why we used it in our title), New Zealand law and the banks officially use the term Parental Leave, as the rules and payments apply to primary carers regardless of gender. We use parental leave throughout this guide!

If you are expanding your family and your property portfolio at the same time, here is a straightforward, judgment-free guide to how New Zealand banks view parental leave, how it affects your borrowing power, and the specific strategies you can use to still get a "yes."

The Bank's Perspective: The Servicing Gap

When a credit assessor looks at your application, their primary job is to ensure you can afford the mortgage repayments both today and in the future.

If you are going on parental leave, the bank knows that your household income is about to take a temporary hit. In New Zealand, the government-funded Paid Parental Leave (as of July 2026) maxes out at $811.05 per week before tax for up to 26 weeks. For most full-time professionals, this represents a significant drop from their standard salary.

If you apply for a mortgage without a solid plan, the bank will calculate your borrowing capacity based on that lower government payment (or a single income, if you are taking unpaid extended leave). This drastically reduces the size of the mortgage you will qualify for.

The Solution: Getting Approved on Your Full Salary

Fortunately, you do not have to wait until you are fully back at work to buy a house. Most mainstream New Zealand banks are perfectly happy to approve your mortgage based on your full, normal salary, provided you can prove that you can safely bridge the temporary gap in your income.

Here are the specific ways we can get the bank to approve your loan while you are on leave:

1. The Cash Buffer Strategy

If your mortgage and expenses will cost $4,000 a month, but your parental leave income is only $3,000 a month, you have a $1,000 monthly shortfall. If you are taking 6 months of leave, the bank will want to see that you have at least $6,000 in a savings account (entirely separate from your house deposit) specifically ring-fenced to cover that gap. Furthermore, if you are taking extended unpaid parental leave, having a substantial cash savings buffer that covers your living costs and mortgage for those unpaid months can still get you approved.

2. The Employer Top-Up

The New Zealand job market is becoming highly competitive, and many great employers now offer parental leave "top-ups" as a perk. If your employer tops up the IRD parental leave payment so that you continue to receive your full 100% salary while you are at home with the baby, the bank's "servicing gap" worry vanishes. We simply show the bank your employment contract proving the top-up, and they can assess you on your normal income.

3. The Single-Income Qualifier

Sometimes, the easiest solution is simply doing the math. If your partner earns a strong salary and your mortgage application actually works based solely on their income without factoring in your parental leave payments at all, the bank will often approve the loan with minimal fuss.

The Essential Paperwork: The Return-to-Work Letter

If you are relying on the Cash Buffer strategy, the bank needs a guarantee that your reduced income is strictly temporary. They will require a formal letter from your employer confirming:

• Your intention to return to work.

• The exact date you are returning.

• The salary and hours you will be returning to (e.g., if you plan to return 3 days a week instead of 5, the bank will calculate your affordability on that new part-time income).

What You Must Disclose

It can be tempting to try and hide a pregnancy from the bank to avoid the extra paperwork, especially if you are in the early stages.

Do not do this.

Applying for a mortgage requires you to sign a legal declaration that you have disclosed any foreseeable changes to your financial situation. A baby is a massive financial change. If you hide a pregnancy and the bank finds out (which they often do when they spot ultrasound payments or baby store purchases on your bank statements), they will instantly decline your application based on a breach of trust.

Honesty is always the best policy, especially because having a baby doesn't mean an automatic "no"—it just means we need to package the application correctly.
