Credit Checks & Mortgage Pre-Approval: What Kiwis Need to Know in 2025
Think of a credit check like a financial X-ray. Lenders need to peek under the hood before they hand over several hundred thousand dollars for your first home. Fair enough, right?
When Do Credit Checks Happen?
The moment you hit "submit" on that pre-approval application, the credit check wheels start turning. NZ lenders don't mess around – they want to know you're legit before getting into the serious stuff.
Types of Credit Checks for First Home Loans
In Aotearoa, lenders do what's called a comprehensive credit check. This shows them:
Pro tip: Some banks market "instant pre-approvals" without credit checks. Don't be fooled – these aren't real pre-approvals. They're more like a "maybe" with a fancy name.
Thanks, I'll continue with the remaining sections while keeping bullet points minimal and focusing on engaging prose.
Impact on Your Credit Score
Here's the thing about mortgage pre-approvals - they'll leave a mark on your credit score. But it's more like a gentle tap than a knockout punch.
If you're smart about it and do all your pre-approval applications within a 14-day window, the credit agencies treat them as one inquiry. It's like buying a coffee for five mates but only paying one EFTPOS fee. Sweet deal, right?
Kiwi lenders aren't expecting you to have a squeaky-clean credit history stretching back to your first paper run. But they do want to see you're reliable with money.
The Big Three Credit Factors
First up, they check your payment track record. Have you been paying your bills on time for the last couple of years? This matters more than that one time you forgot about your Trade Me success fee back in 2020.
Next, they look at your current credit use. Maxing out your credit cards is a red flag bigger than the one at the local dairy. Keep your credit card balances low - ideally under 30% of your limits.
Finally, they check how many times you've applied for credit recently. Applying for three personal loans, two credit cards, and a car loan right before seeking pre-approval? Yeah, nah. That's not going to fly.
Let's talk about transforming yourself into a mortgage lender's dream applicant. It's not about becoming a different person - it's about presenting your financial story in the best light possible. Aera’s First Home Coach will support you to ensure you are mortgage-ready for your first home.
The Documentation Dance
First up, let's get your paperwork sorted. NZ lenders love seeing a well-organised application more than a perfectly made flat white. Here's your hit list:
Income proof? You'll need your last three months of payslips and bank statements. Self-employed? Grab your last two years of tax returns and get your accountant on speed dial.
Pop all your KiwiSaver details together too. Most Kiwis have about $21k each in their KiwiSaver, and that can be a game-changer for your deposit.
Your Income Story
Here's something most people don't know - lenders look at your income differently than you do. That $69k salary? They're not just multiplying it by five and calling it a day.
They're checking if your income is stable. Been in your job for less than three months? That might raise eyebrows. But if you've switched jobs for a pay bump in the same industry, you're probably sweet.
Got a side hustle? Choice. Lenders will usually count it if you've been at it for at least six months. Just make sure you can prove that income with some solid paperwork.
Debt-to-Income: The Magic Number
Ever heard of DTI? It's like your financial BMI - a quick health check of your money situation. Lenders typically want your total debt payments to be less than 35% of your take-home pay.
Quick example: If you're bringing home $5,000 a month, they don't want to see more than $1,750 going to debt payments. This includes your potential mortgage payment too.
The Deposit Situation
Let's bust a myth: you don't always need a 20% deposit. If you're buying new (like the beautiful new builds we've got at Aera), you might only need 10%. On a $700k home, that's the difference between needing $140k and $70k.
Your deposit can come from:
Employment: Stability is Key
Lenders love seeing a stable job history. But what counts as stable? Generally, if you've been employed full-time for at least three months in the same industry, you're looking good.
Contractors and freelancers, don't stress. Lenders will usually want to see two years of steady income. It might take more paperwork, but it's totally doable.
The KiwiSaver Factor
Your KiwiSaver isn't just a nice-to-have - it's often your secret weapon for pre-approval. Been a member for three years or more? You can likely use it for your deposit.
Hot tip: Check your KiwiSaver balance now. The market's been doing pretty well lately, and you might have more saved than you think.
Getting Bank Fit
Think of pre-approval like training for a big game. You need to be in top financial shape three months before you apply. That means:
Pay everything on time. Set up automatic payments if you need to. Late payments are like own goals - they'll hurt your chances.
Keep your spending consistent. Now's not the time to YOLO your savings at Queenstown for a week. Lenders will be eyeing your statements like a ref watching for a forward pass.
Build up your savings history. Regular deposits into your savings account show you've got good money habits. Even small amounts add up to a good impression.
Pre-approval might seem like a mission, but it's just part of the journey to your first home. And hey, that's why we're here. At Aera, we've helped thousands of Kiwis get pre-approved faster than they thought possible.

Can I Still Get Pre-Approved with Average Credit?
You don't need a perfect credit score to get pre-approved. Banks understand you're human. What matters is showing them you've got your act together now. If you've had some hiccups but you're back on track, many lenders will still give you a shot.
How Long Does Pre-Approval Last?
Most NZ banks give you 90 days of pre-approval. Think of it as a three-month ticket to house hunting. After that, you'll need to reapply - but hey, at least you know the process now.
What About Multiple Pre-Approvals?
Go ahead and shop around different lenders. Just keep it within that magic 14-day window to protect your credit score. Different lenders offer different rates and terms - it's worth checking out your options.
