Non-bank lenders: a reliable alternative for your mortgage?

I’m Yatin Kainth, a mortgage adviser in Auckland, and I place loans with both banks and non-bank lenders. The moment I mention a lender that isn’t one of the big names, a lot of clients go quiet. I get it. This guide covers how non-bank lenders work, when I’d use one, what they cost and what I’d check before signing anything.

If a bank has just turned you down, read what to do after a home loan is declined first. You want to know why before you apply anywhere else.

Non bank lenders NZ: what are these lenders for home loans?

People call them non-banks, bank alternatives or second-tier lenders. They all mean the same thing: a business that lends money but isn’t a registered bank. In New Zealand you’ll mostly come across these:

• Credit unions and building societies. Many are member-owned. In my experience that often means more personal service, and a little more give for low-risk borrowers who don’t tick every bank box.
• Specialist mortgage lenders. Their whole business is lending that sits outside standard bank criteria: self-employed income, credit problems and more complicated property investment loans.
• Short-term lenders. Some lenders exist to fix a short-term problem, such as bridging finance NZ lenders offer, and have no interest in holding your loan for 30 years.

The banking licence is what separates them. Non-banks aren’t registered banks, so they aren’t bound by the same bank lending rules and they write their own credit policy. That’s where the flexibility comes from.

Are non-bank lenders safe and regulated?

A lot of people assume non-bank lenders are dodgy, or at least less reliable than a bank. That’s not what I see. The lenders I work with are established businesses. And every lender offering consumer credit in New Zealand, bank or not, has to follow the lender responsibility principles in the Credit Contracts and Consumer Finance Act. Before lending, they have to make reasonable inquiries to be satisfied the loan suits you and that you can repay it without substantial hardship. Since 1 July 2026 the Financial Markets Authority has been the regulator for those rules, taking over from the Commerce Commission.

The difference is the rulebook they lend under. The Reserve Bank’s loan-to-value (LVR) and debt-to-income (DTI) restrictions apply to registered banks, not to non-bank lenders, and banks layer their own fairly rigid credit policies on top. Non-banks have more room to look at your whole situation. That’s a reason to check each lender properly. It isn’t a reason to rule them out. Look at how long the lender has been around and its track record, and ask your adviser how it treats borrowers when their circumstances change.

When a home loan from a non bank lender makes sense

These are the situations where I most often look past the banks.

Your income is hard to prove the way a bank wants

This comes up all the time with self-employed people, contractors and anyone whose income moves around month to month. Banks are very particular about the documents they want, and those documents aren’t always easy to produce. Some non-bank lenders take a wider view of your finances and will accept other evidence. My page on home loans for self-employed borrowers goes into more detail.

You have past credit issues

Maybe there’s a default on your credit report, a judgment or a past bankruptcy. Banks will often decline without asking what happened. Specialist lenders are more likely to look at the reason, how long ago it was and how you’ve handled money since. I go through this properly on my bad credit options page.

You’re growing a rental portfolio

The way banks work out affordability can cap how many rentals you can hold. Banks also tend to tie your properties together as security for all your lending. Some non-bank lenders will keep each property separate, which can leave you more room to move later on.

Your age shortens the loan term a bank will use

Banks generally want your home paid off by the time you retire. That can shorten the loan term they assess you on, which pushes the repayments up until the numbers stop working. Some non-bank lenders look at this differently.

You need a short-term fix, or a loan the bank doesn’t offer

Bridging finance, some construction loans and other loans for a specific purpose are areas where non-banks often fill the gap.

And non-banks aren’t only for people who’ve been declined. I’ve had clients who didn’t qualify for a particular first home scheme find that a credit union offered them terms that were genuinely competitive. If you’re buying your first home, have a look at my first home buyers and low deposit home loans pages too.

What a non-bank loan costs you

The flexibility isn’t free. Before you go ahead, expect some or all of these:

• A higher interest rate. Pricing is mostly based on your risk profile, so the messier your situation, the higher the rate tends to be. For some people the gap to a bank rate is small. For others it’s big. It depends on the lender and on you.
• Fees. Some lenders charge establishment or other fees a bank might not, and non-bank lending usually carries an adviser fee as well (more on that in the FAQ below). Get every fee in writing and compare the total cost, not just the rate.
• A bigger deposit. Some non-bank lenders want more equity than a bank would, particularly when credit or income is the sticking point.
• A short term. Some loans are built to last a year or two. If yours is one of them, you need a realistic plan for what happens at the end.

Plan your exit before you sign

With any non-bank loan, I want the next step agreed on day one. For some clients the non-bank lender is a long-term home and there’s no reason to move. For others the aim is to build a clean repayment record and then refinance back to a bank once their situation allows. Sometimes a short-term loan, or a first and second mortgage used together, bridges the gap in between.

What I won’t do is put you into a short-term loan without an honest conversation about what happens if refinancing isn’t available when you expect it to be. If consumer debt is part of the picture, debt consolidation might belong in the plan as well.

How to choose between a bank and a non-bank

1. Find out why the bank said no, or why it would. Sometimes a bank is still on the table if the application is put together properly.
2. Compare the total cost. Add up the rate, the fees and any other costs over the time you expect to have the loan.
3. Check the lender. Look at its history, its reviews and how it treats borrowers when things change.
4. Agree the exit plan. Know whether this is a long-term loan or a stepping stone.
5. Get advice from someone who deals with both. An adviser who only uses banks can’t show you the whole market. One who only uses non-banks might put you on a higher rate than you need.

The best mortgage for you is the one that fits your situation. It won’t always be the one with the most familiar name.
