Meet JJ

Hi, I am JJ — your local mortgage adviser on the Hibiscus Coast.

Most of the people I work with are buying their first home. Some are refinancing, some are investing, some are building. The mix changes — but the approach does not. I take the time to understand your situation, explain what is actually possible, and help you make a confident decision.

I compare across 25+ lenders, structure the deal properly, and walk you through every step. From the first conversation to the day the funds settle, you have someone in your corner who actually picks up the phone. The first chat is free — no pressure, no jargon, no obligation.

How I can help

Four ways I work with clients.

First home buyers are the biggest part of my work, but I also help refinancers, investors, and new build clients. Click through for the detail, or just call and we will work it out together.

First Home Buyers

Deposit options, KiwiSaver, Kāinga Ora First Home Loan eligibility, and lender appetite for new buyers. The full path from "thinking about it" to keys in hand.

First home buyers

Refinance

Rate reviews, cashback offers, structure rebuilds, and break-fee maths. If you have not reviewed your loan in two years, you are probably overpaying.

Refinance

Investment Property

DTI rules, equity release, multi-property structures, and lender appetite for investors. I help you grow without overstretching.

Investment

New Build

Building gives you flexibility on deposit and exemption from some LVR rules. The financing process is different — I will walk beside you from start to finish.

How it works

From first chat to funded deal.

Four steps. Most clients move from initial conversation to settlement in 4 to 8 weeks, depending on their situation.

1

Free consultation

30-minute chat. No cost. We work out what you actually need and whether I am the right person to help.

2

Strategy & lender match

I compare your situation across the lender panel, structure the deal, and recommend the best path.

3

Application & approval

I prepare and submit your application, manage the lender conversation, and chase down approvals.

4

Settlement & ongoing review

Funds settle, you get the keys (or the better rate), and I check in annually to keep your loan working.

Common questions

Things people ask before getting in touch.

I am a first home buyer — where do I start?
The best first step is a free 30-minute chat. We work out what your deposit actually looks like (savings, KiwiSaver, gifted funds), whether you qualify for the Kāinga Ora First Home Loan, and roughly what you could borrow. From there we map the path to a pre-approval and then to an offer.
How much does it cost to use a mortgage adviser?
Nothing to you. The lender pays my commission when your loan settles. You get full advice, application support, and ongoing reviews at no cost. If for some reason a deal is not paid by the lender, I will tell you upfront before any work starts.
How long does pre-approval take?
Approval timeframes vary depending on the lender and your circumstances. Some approvals are quick, while others take longer. I keep you informed and follow up to make sure the process moves smoothly.
Do you only work with the big four banks?
No. I compare across 25+ bank and non-bank lenders — the four majors, second-tier banks, and specialist lenders for situations the big banks will not look at.
I have been declined by my bank. Can you still help?
Often, yes. A decline from one bank does not mean every lender will say no — different lenders have different criteria and appetites. I look at where your situation actually fits and take it to the lender most likely to approve it.
How are you different from going direct to a bank?
A bank can only offer its own products. I compare the whole panel, structure the deal around your situation, and manage the process from first chat to settlement — and there is no fee to you.
Can I use my KiwiSaver towards the deposit?
Often, yes. Many first home buyers withdraw from KiwiSaver to help fund their deposit if they meet the criteria. I help you work out what counts, what you may be eligible for, and how it fits alongside your savings and any gifted funds.
How much can I borrow?
Lenders test affordability against your income, your regular expenses and any existing debts — and every lender's servicing test is different. Rather than a generic number, I work out what is realistic for your situation and take it to the lender most likely to say yes.
What documents will I need to apply?
Usually proof of ID, recent payslips, a few months of bank statements, and tax summaries if you are self-employed. I give you a clear checklist upfront so nothing slows your application down once it is in.
Should I fix or float — and for how long?
It depends on how much certainty you want and what is ahead for you. Most New Zealand home loans use a mix of fixed and floating rather than all-or-nothing. I talk through the structure that suits your plans rather than pushing a one-size-fits-all answer.

JJ is highly recommended. He helped and guided us successfully into our new home 3 years ago, and continues to be up front and honest with options moving forward.

With the assistance of JJ at Mortgage Design we managed to buy our first house without any dramas. The purchase was made easy, with JJ doing all the mortgage structure.

JJ is by far and away the best broker we have ever dealt with. He has been with us through two properties now and multiple refixes — couldn’t recommend higher!
