Mortgage Broker for First Home Buyers in New Zealand

Buying your first home should be exciting! But in reality, many first time home buyers come to us feeling overwhelmed by bank jargon, unsure what they could afford, or rejected by banks altogether. 

At OneStop Financial Solutions, we help first home buyers understand their options, avoid common mistakes, and secure a mortgage that fits their situation.

Our role is simple: give you clear advice, compare lenders for you, and guide you through the process from planning to settlement. Clients repeatedly tell us we made the impossible possible and turned uncertainty into a clear plan they could follow with confidence. 

How We Help First Home Buyers at Every Stage

Personalised First Home Buyer Advice

Every first home buyer’s situation is different. We take the time to understand your income, deposit, KiwiSaver balance, and goals, then explain your options clearly. You’ll get easy to understand advice, tailored to your needs.

KiwiSaver & Government Support Guidance

If you’re eligible, KiwiSaver can form a major part of your first home buyer deposit. We help first home buyers understand how KiwiSaver first home withdrawals work, whether you can qualify for a Government supported first home loan, and how government schemes affect lender choice and approval

Pre-Approval & Borrowing Power

We calculate what lenders are likely to approve. This includes deposit requirements, loan servicing limits, interest rates, and ongoing repayments. Pre-approval gives you clarity before you start house hunting. We also explain how lenders mortgage insurance works, debt to income ratios, and how your credit score works.

Negotiating with Lenders on Your Behalf

Different lenders assess first home buyers differently. We compare interest rates, deposit requirements, flexibility within the loan and more. Our job is to match your situation to the right lender, not push you into the easiest approval.

Ongoing Support Beyond Settlement

Your first mortgage isn’t set-and-forget. We stay involved to help with reviewing interest rates, adjusting your repayments and strategies to pay off your home loan faster. If your situation changes, we can help you refinance, or buy your first investment property when you’re ready.

Why First Home Buyers Use a Mortgage Broker

First-time buyers often assume their only option is to go directly to their bank. In reality, a mortgage broker gives you access to multiple lenders, clearer advice, and stronger approval strategies.

Using a mortgage broker for your first home loan helps you:

  • Compare first home buyer mortgage lenders, not just one bank
  • Understand how much you can borrow as a first-time buyer
  • Structure your loan to suit your income, deposit, and long-term plans
  • Avoid common mistakes that cause delays or declines
  • Reduce stress by having one adviser manage the process

Many first home buyers tell us they finally felt confident once everything was explained in an easy to understand way and laid out step-by-step. Read more about how to get a mortgage.

We first worked with Matt Willoughby and the team at OneStop a couple of years ago as first home buyers, and they were absolutely fantastic. They made what felt like the impossible happen and helped get my partner and me over the line.

Since then, we've continued working with them including taking the plunge into "adulting" by sorting out both life insurance and health insurance. Matt and the team made the whole process simple and easy to understand, walking us through every step.

We've now used them for all our insurance needs over the years, and they’ve always gone above and beyond. Such a great team and genuinely helpful, professional, and always with your best interest at heart. Couldn't recommend them more highly!

Matt and his team were brilliant. They helped out, and answered every question I had every step of the way. And with their help and knowledge, I was ultimately able to make "what previously seemed to only be a dream" turn into a reality! And that was to purchase my first property! At the ripe age of 47 I may add 🙂. Thanks again for everything guys! Yous rock!

Patient and knowledgeable. Matt guided us through our first home purchase and, a few years later, organised insurance for the family (with a pretty non-standard situation and series of requests). Thanks again!

Frequently Asked Questions

The standard deposit for buying a home in New Zealand is 20%. Lower deposit options may be available for you. Speak to our mortgage brokers about your circumstances. 

Your borrowing amount depends on income, existing debts, interest rates, and lender rules. You may like to explore our mortgage repayment calculator for example loan amounts and repayments.

Most first home buyers receive a free service. We are compensated by lenders upon settlement. Read our disclosure statement for more information. 

In 2026, eligible first home buyers can make a KiwiSaver withdrawal to help with a deposit, and some may be eligible for a welcome home loan, with lower deposits backed by selected lenders.  

First home buyers usually access the same rates as other owner-occupiers. Your interest rate depends on the lender, your credit score, and loan structure. 

A mortgage broker compares multiple banks and non-bank lenders, while a bank only offers its own products. Feedback from borrowers tells us they found using our brokers easier than going directly to a bank.
