As a business owner, owning the premises you trade from has real advantages — stability, control, an asset that builds equity over time, and the ability to customise your space without landlord approval. But a commercial property purchase is also one of the most significant financial decisions a business will make, and there are important legal and financial considerations to work through before you sign anything.
This article walks through the four key areas every NZ business owner should understand before purchasing commercial premises.
Who needs to know this
This article is for:
- Business owners considering purchasing the premises they currently lease
- Entrepreneurs looking to buy commercial property as an investment alongside their business
- Company directors weighing up ownership structures for a new acquisition
- Anyone who has been told “just buy it through the company” without fully understanding what that means
1. Ownership structure — getting this right from day one
The most important decision you make before purchasing commercial property is who buys it. Your options broadly are:
- As an individual — straightforward, but exposes personal assets to commercial liability, and the property forms part of your personal estate.
- Through your trading company — keeps the asset in the business, but if the business fails the property is at risk.
- Through a separate property-holding company — common for separating trading risk from the property asset. The holding company owns the property and leases it back to the trading company.
- Through a family trust — protects the asset from creditors in many scenarios, can assist with succession planning, but adds compliance overhead.
- Through a partnership or joint venture — relevant if you are co-investing with others; requires a written partnership or joint venture agreement.
| Structure | Asset protection | Tax flexibility | Succession / exit | Complexity |
|---|---|---|---|---|
| Individual | Low — personal liability | Simple | Straightforward | Low |
| Trading company | Medium — company liability | Moderate | Tied to business sale | Low |
| Holding company | High — separated from trading | Good | Flexible | Medium |
| Family trust | High — creditor protection | Depends on trustee structure | Complex | High |
| Partnership / JV | Shared — depends on structure | Varies | Requires exit clauses | Medium–High |
There is no universally “right” answer — the best structure depends on your personal tax position, the size of the business, your plans for growth or exit, and your family situation. Get advice from your lawyer and accountant before the purchase, not after.
Choosing the wrong ownership structure at the start is expensive to fix later — restructuring after settlement can trigger stamp duty equivalents, GST complications, and refinancing costs.
2. GST — most commercial transactions are zero-rated, but the detail matters
GST is one of the most misunderstood aspects of commercial property in New Zealand, and getting it wrong can result in unexpected tax bills running into hundreds of thousands of dollars.
The zero-rating rule
Most commercial property purchases between GST-registered parties are zero-rated rather than standard-rated (15%). This means:
- No GST is added to the purchase price
- The buyer does not need to fund GST at settlement, then claim it back later
- The transaction is still a “taxable supply” — it is just rated at 0%
For zero-rating to apply, both the vendor and the purchaser must be GST-registered, and the property must be sold as a going concern (i.e. the vendor is currently using it in a taxable activity).
Where it goes wrong
Issues arise when:
- The buyer is not GST-registered at settlement (even if they intend to register)
- The property is partly used for residential purposes (which is exempt, not zero-rated)
- The agreement does not correctly specify the GST treatment on the face of the contract
- A buyer assumes zero-rating applies without checking
If the zero-rating rules are not met, the standard 15% GST applies and the buyer must fund that at settlement. On a $2 million property, that is an extra $300,000 you need at settlement.
Other tax considerations
Beyond GST, owning commercial premises affects your tax position in other ways:
- Interest deductibility — interest on your mortgage is deductible against your rental income (if leasing to your trading entity) or against your business income directly.
- Depreciation — commercial buildings can be depreciated for tax purposes, reducing your taxable income each year.
- Bright-line and capital gains — New Zealand does not have a general capital gains tax, but the bright-line test applies to residential land. Commercial land is typically outside the bright-line rules, though the “land tainting” rules can apply if your business involves land dealing.
Your accountant should model the full tax picture for your specific situation before you commit.
3. Refinancing for business growth
One of the underrated advantages of owning your business premises is the ability to leverage rising property values to fund business growth.
As the property appreciates in value, the gap between what you owe (your mortgage) and what it is worth (the equity) grows. Banks are generally willing to lend against that equity, giving you access to capital without selling the property.
How businesses use this in practice
- Funding a fit-out or equipment upgrade
- Acquiring a competitor or adjacent business
- Bridging cash flow during a period of rapid growth
- Funding a buy-out of a business partner
The mechanics of refinancing are relatively straightforward with good legal and financial advice. The key is ensuring the loan structure matches how you intend to use the funds — mixing business and personal borrowing in a single facility can create tax complications.
4. Reconfiguring and making the most of the space
Owning your premises gives you freedom that tenants simply do not have. You can:
- Redesign the layout to suit your operations, without landlord consent
- Subdivide the space and lease part of it to another tenant, creating a rental income stream that offsets your mortgage costs
- Make capital improvements that increase the value of the asset (rather than improving a landlord’s property at your cost)
- Convert unused space — storage areas, mezzanines, or car parks can sometimes be converted to additional lettable area
What to watch for
Before undertaking significant works, you will need to check:
- Building consent requirements — under the Building Act 2004, most structural changes and changes of use require consent from your local council.
- Resource consent — zoning rules may restrict certain uses within the space.
- Your own mortgage covenants — some lenders restrict material alterations without their approval.
- Existing tenants — if you are buying a property with sitting tenants, their leases are binding on you as the new owner.
If you plan to bring in a tenant, you will need a commercial lease agreement that complies with the Property Law Act 2007. The standard ADLS Deed of Lease is widely used in New Zealand and provides a robust starting point — but it should be reviewed by a lawyer before signing, as it contains significant obligations for both parties.
Before you sign — commercial property purchase checklist
0/0 completeThe process from agreement to settlement
-
Step 1
Sign the Agreement for Sale and Purchase
Usually conditional — common conditions are finance approval, satisfactory building inspection, and LIM review. Your lawyer should review the agreement before you sign.
-
Step 2
Satisfy conditions
Work through due diligence during the conditions period (typically 10–15 working days). Your lawyer reviews the title, instruments, and LIM; your accountant confirms the tax structure; your bank approves finance.
-
Step 3
Go unconditional
Once all conditions are satisfied (or waived), the agreement becomes unconditional. You are committed. Settlement date is typically 20–30 days from going unconditional.
-
Step 4
Pre-settlement
Your lawyer prepares transfer documents, requisitions on title, and coordinates with the vendor’s solicitor and your lender. You complete a final inspection.
-
Step 5
Settlement
Funds transfer, title transfers to the new owner (or ownership entity), and keys are released. Your lawyer registers the transfer and mortgage at LINZ.
Common mistakes to avoid
The most common costly mistakes we see in commercial property purchases:
- Signing unconditionally at auction without legal review — commercial properties are sometimes sold at auction. Ensure you have reviewed the title and instruments before bidding, as there is no cooling-off period.
- Choosing the wrong ownership entity — buying through the trading company when a holding company structure would have been more appropriate, then needing to transfer later.
- Assuming GST zero-rating without checking — zero-rating requires both parties to be GST-registered at settlement. Check early and document it correctly in the agreement.
- Not reviewing existing leases — if the property has tenants, their rights carry over to the new owner. A poorly structured lease can significantly constrain what you can do with the property.
- Underestimating settlement costs — beyond the purchase price, budget for legal fees, LIM fees, building inspection, any LINZ registration fees, and potentially a valuation for finance purposes.
