But your bank is just one lender in a much wider market. And because lenders don’t all assess borrowers the same way, looking beyond that one option can make a big difference. 

So, what are the advantages of going directly to your bank? And when might it pay to look further afield?

Going straight to your bank

There are good reasons why your own bank might be your first port of call. 

• They already know you. Your bank has an existing relationship with you and visibility over your accounts and financial history.
• You know them too. You're already familiar with how they operate and may have been banking with them for years.
• It can feel simpler. Dealing with one organisation is appealing when you're already juggling open homes, KiwiSaver paperwork, lawyers and everything else that comes with buying property.

But there’s a flip side:

• You’re only getting one lender’s view. Another lender (bank or non-bank) could look at your circumstances and reach a different conclusion.
• Your options are limited to that bank. They can only offer their own lending products, assessed against their own criteria.
• They can’t compare their answer with the wider market. If your circumstances don't fit what they’re looking for, they won’t point you toward a competitor who might say yes. 

None of this makes going directly to your bank a bad option. It just means you're looking at your mortgage through one lender's lens, rather than the whole market's.

What if your bank says no? 

A “no” from your bank can feel pretty final, especially if you assumed they were the obvious route into your first home.

But here’s something first-home buyers don’t always realise: lenders don’t all look at a mortgage application the same way.

Every lender must meet New Zealand’s responsible lending requirements¹. Beyond that baseline, though, each has its own policies for weighing up your income, expenses, existing debt and borrowing capacity. Appetite for different types of lending varies too. 

Put simply the same borrower could get different answers from different lenders.

So if your bank declines your application, start by finding out why. Depending on the reason, another lender may see things differently. In some cases, a non-bank lender might be worth exploring too, since their approach can differ again.

That doesn’t mean reapplying somewhere else straight away is always the right move. Sometimes the better step is building a larger deposit or paying down debt before trying again. 

Either way, one lender’s answer is not the full picture.

Why exploring your options makes sense

Looking across different lenders is especially valuable when your financial circumstances aren’t straightforward. For example, you might:

• Be self-employed or have variable income.
• Have less than a 20% deposit.
• Carry a high level of existing debt.

None of these automatically rule out getting a mortgage. But they do make your choice of lender matter more, since how each weighs up the same fact can vary. 

Even if your situation is straightforward, it's still worth knowing what else is out there. So how do you actually compare those options?

Working with a mortgage adviser

This is where a mortgage adviser can be useful.

Rather than being limited to one lender’s products and lending criteria, mortgage advisers generally work with a panel of lenders. That can include both banks and non-bank lenders, giving advisers the ability to consider different options against your unique circumstances. 

A mortgage adviser can also help you look beyond the advertised interest rate. How much a lender is prepared to lend, repayment flexibility, mortgage features, fees and structures are all important factors to compare.

Importantly, working with an adviser doesn’t necessarily mean leaving your existing bank. After comparing your options, staying with them may still make the most sense. The difference is that you’ve had the opportunity to explore what else is available first.

What does it cost to work with an adviser?

Mortgage advisers are commonly paid by the lender you choose once your loan settles. In many cases, that means there may be no direct fee for standard residential mortgage advice.

However, fees can apply in some circumstances, and how advisers are remunerated varies depending on the lender and the work involved. Your adviser should explain how they’re paid and disclose any applicable fees before you proceed.

Let's make sure your bank is right for you

Sticking with the bank you've been with for years might be your best option. And if it is, great.

The key is to look at the bigger picture before making that decision.

That’s something your Mortgage Link adviser can help you do. We can compare options from the bank and non-bank lenders we work with, look beyond the headline rate and consider how different mortgage structures could work for your situation.

We’ll also help with the application process, communicate with the lender on your behalf and explain the details in plain English, so you understand your options and can make an informed decision.

And our support isn’t just for first-home buyers. If you already have a mortgage, we can help you review whether it still suits your circumstances.
