Most New Zealand business owners who own property also have a mortgage on it. That’s normal. The question is whether the equity above that mortgage can be put to work for the business — and how to do it without disrupting the home loan you already have.
Your two options
Option 1: a top-up from your existing bank
Ask your current bank to increase your mortgage and release funds. It’s the obvious first call, and for some owners it works well. But banks will typically:
- reassess your whole lending, including personal income, expenses and existing debt;
- apply their own LVR and debt-to-income policies (the Reserve Bank’s DTI rules apply to banks’ residential lending);
- want full business financials and tax returns if the funds are for the business;
- take time — sometimes weeks.
If the business has had a tough year, the accounts are behind, or you need the funds quickly, a bank top-up can stall.
Option 2: a second mortgage with another lender
A second mortgage is a loan from a different lender, secured on the same property, that ranks behind your existing mortgage. Your bank stays first; the new lender takes second position.
For business-purpose funding, this route has real advantages:
- Your home loan stays as it is — same bank, same terms.
- Assessment focuses on equity and purpose, not your full personal financial profile.
- Speed — business-purpose second mortgages can move much faster than a bank reassessment.
- Flexibility with credit history — some lenders consider defaults and arrears case by case.
How a second mortgage works, step by step
- Equity check. The lender estimates the property’s value and adds up what’s already secured on it.
- Combined LVR. It works out the combined loan-to-value ratio including the new loan, and checks it against its own maximum for that property type and location. Our LVR guide explains the maths.
- Purpose and exit. It confirms the funds are for business and how the loan will be repaid over a short to medium term.
- Valuation. Often a registered valuation, sometimes a desktop assessment depending on the lender and property.
- Legal work. Lawyers prepare and register the second mortgage on the title with Land Information New Zealand (LINZ). If your first mortgage requires the bank’s consent, that’s arranged.
- Settlement. Funds are paid — to you, to a supplier, or directly to IRD or another creditor.
First vs second mortgage at a glance
| First mortgage | Second mortgage | |
|---|---|---|
| Ranks | First — paid first from any sale | Behind the first mortgage |
| Typical lender | Bank | Non-bank or specialist lender |
| Typical max combined LVR | Higher | Lower, because of second-ranking risk |
| Pricing | Priced on the lender’s view of risk | Usually reflects second-ranking position |
| Existing home loan | Replaced or increased | Left untouched |
What does it cost?
Second-mortgage pricing reflects the higher risk of ranking second, so it’s usually priced differently from a bank home loan. Every loan is priced on the individual circumstances — the equity, the property, the loan size, the purpose and the exit. The best way to compare is by total cost over the time you’ll actually have the loan, including establishment and legal costs, rather than a single headline figure.
Because many business-purpose second mortgages are short to medium term, the plan to repay matters. Common exits include:
- a bank refinance once financials are up to date;
- a property or business sale;
- a large contract payment or debtor settling;
- steady repayments from improved trading.
Using someone else’s equity
If you don’t own property but a family member or your family trust does, their property can secure a business loan as a supporting party. They’ll need independent legal advice and should fully understand that their property is at risk if the loan isn’t repaid. This is common in New Zealand family businesses, and done properly it can open doors a bank would keep shut.
Before you apply: a checklist
- Know your numbers. Rough property value, current mortgage balance and any revolving credit limit.
- Check your first mortgage. Find your loan documents or ask your bank whether consent is needed for a further charge.
- Be clear on purpose. “Clear $62,000 GST and PAYE arrears and fund two months of wages until the Ōmokoroa contract pays” is strong.
- Think about the exit. How and when will it be repaid?
- Gather ID for every owner of the property.
Things to watch
- Don’t over-borrow. Take what the business needs plus a sensible buffer, not the maximum available.
- Read the default terms. Understand what happens if a repayment is missed.
- Watch the combined debt. Two mortgages means two sets of repayments; budget for both.
- Plan the refinance early if that’s your exit. Start the conversation with the bank months ahead.
