Buying a Cross-lease Property
Insight
Cross-lease properties are common across New Zealand, especially in older suburbs. While they can offer affordable entry into popular areas, they come with legal complexities that many first-time buyers do not understand. Because the land is jointly owned, changes to your home or land often require neighbour approval and updates to the official flats plan.
This guide explains how cross-leases work in plain language so buyers know what questions to ask and what risks to avoid.
How Shared Ownership Works
On a cross-lease, all owners share ownership of the land. Each individual home is leased back to the owner for a long term (often 999 years). This structure means neighbours must cooperate for changes affecting any part of the shared land.
Footprint & Flats Plan Mismatches
One of the most important checks is ensuring the dwelling’s physical footprint matches the flats plan. If a deck, extension, porch, garage or enclosure was added without updating the plan, it is considered a defect.
This can affect:
- insurance
- lending approval
- future renovations
- value and resale
Unsure if the footprint matches?
A lawyer can confirm whether the flats plan matches the building and whether any issues require negotiation or title correction.
Renovations & What You Can’t Do Without Consent
Most external alterations — even small ones — require written approval from all other landowners. Common consent-required changes include:
- extensions
- decks
- sheds
- garages
- porch enclosures
If previous owners made unapproved changes, you may inherit the problem.
Common Issues Buyers Overlook
Common pitfall:
Assuming a council building consent means the flats plan was updated. These are completely separate processes.
Issues frequently discovered during due diligence include:
- unapproved alterations
- flats-plan boundary encroachments
- disagreements between neighbours
- driveway or access disputes
- restrictive covenants limiting future alterations
Because cooperation between owners is required, longstanding disputes can make living in a cross-lease home difficult.

Frequently Asked Questions
What is a cross-lease property?
A cross-lease property is where multiple owners share ownership of the land and lease their exclusive area (their flat) from the group. Each owner is both a landowner and a lessee. The flats plan defines the exact footprint of each dwelling.
Why do cross-leases confuse buyers?
Because buyers expect freehold ownership. Cross-leases restrict alterations, extensions, sheds, decks and sometimes even repainting unless all neighbours agree and the flats plan is updated.
What is a flats plan?
The flats plan is part of the title and shows the exact outline of each dwelling. If your house footprint differs from the flats plan—even slightly—it is considered a defect and may affect insurance, lending and resale.
Can I renovate or extend a cross-lease home?
Only with all other owners’ written consent, and often only after amending the flats plan. This process can be costly and time-consuming. Many cross-lease disputes arise from unapproved alterations done by previous owners.
Do banks treat cross-lease differently?
Some lenders view cross-lease as higher risk, especially if the flats plan does not match the actual dwelling. Valuations may also be more conservative.
