Why Cross Lease Converter took Auckland Council to the Environment Court — and won
By Brent Clode
Article 4 in our ongoing series for Auckland real estate professionals on cross leases, property values, subdivision law and marketing opportunities.
1. A common misconception about cross lease conversions
There is considerable information on the internet suggesting that converting a cross lease property to fee simple requires owners to alter existing dwellings, separate drainage systems, improve driveways or bring infrastructure up to current development standards. This information can discourage owners from considering conversion and lead real estate agents to assume the process will be expensive or complicated.
For a conversion involving lawfully established dwellings and existing services, this is incorrect.
Cross Lease Converter has consistently maintained that existing, lawfully established development should not be treated as new development simply because the form of title is changing. This principle was central to our successful Environment Court appeal against Auckland Council in April 2024.
2. Why we challenged Auckland Council
Cross Lease Converter, through Development Partners Management Limited, funded and supported the proceedings that led to the Environment Court decision:
McDonnell & Mackenzie v Auckland Council [2024] NZEnvC 076 — 11 April 2024.
The case involved two existing cross lease dwellings at 86 and 86A Michaels Avenue, Auckland. The owners wanted to convert their two cross lease titles into separate fee simple titles. There was no proposal to build additional houses or intensify the residential use of the property.
Auckland Council granted subdivision consent but imposed conditions requiring the owners to demonstrate that the existing wastewater and stormwater systems were fit for purpose. These conditions went beyond identifying where the services were located. They required the owners to establish that the existing drainage systems were functioning adequately. We considered that approach inconsistent with the purpose of a conversion involving existing lawful development.
The matter proceeded to the Environment Court.
3. What the Environment Court decided
The Environment Court agreed that the disputed conditions could not be imposed in the circumstances of this controlled activity conversion. The Court made several important findings.
A. A conversion changes the title, not the physical property
The Court explained at paragraph [52]:
"In simple terms, the purpose of a cross lease subdivision is to replace a composite (freehold/leasehold) record of title with a freehold record of title."
In other words, the existing buildings and services remain as they are.
B. Existing services must be located
The Court confirmed that the relevant subdivision standard concerns the location of service connections and on-site infrastructure. Where services cross new property boundaries, appropriate legal rights may need to be established, usually through easements.
C. Council cannot require existing pipes to be proven fit for purpose
At paragraph [30], the Court found that the relevant specific standard concerned the location of services and did not extend to their condition, adequacy or functionality. For the conversion before the Court, this meant Council could not use the title conversion to require additional testing or upgrades of existing drainage systems merely to establish that they were fit for purpose.
D. The appeal succeeded
The Environment Court allowed the appeal and cancelled conditions 8 and 9, which related to the adequacy of the existing wastewater and stormwater systems. The judgment provides important guidance for qualifying cross lease conversions across Auckland and New Zealand.
4. What about existing houses and driveways?
For a standard conversion, the objective is to create separate fee simple titles around existing, lawfully established dwellings. The conversion itself does not require:
Existing development must have existing use rights which is demonstrated by a building permit or consent.
The important distinction is that converting the title does not, by itself, make an otherwise lawful existing house or service system a new development.
5. What does Auckland Council need to know about drainage?
One area that continues to require attention is the location of existing private stormwater and wastewater infrastructure. Auckland Council has a legitimate interest in establishing where services are located and ensuring that the new titles have appropriate legal rights to use them. For example, if a wastewater or stormwater pipe serving one proposed lot crosses the other lot, an easement may be required. Likewise, where a stormwater soakage system serves an existing dwelling, its location may need to be identified on the relevant plans. This is where CCTV drainage investigations to establish an as-built drainage plan is essential.
The objective is to locate the existing infrastructure and establish the appropriate legal arrangements.
6. The practical difficulty with older stormwater systems
In our experience, most conversions proceed without significant problems involving the existing infrastructure. However, some older Auckland properties present challenges. Common issues include:
These issues can make it difficult to establish the precise location of the infrastructure. In some cases, limited investigation or remedial work may be necessary to locate the services accurately. This is not the same as requiring all existing drainage systems to be reconstructed or upgraded to modern standards.
7. Repairs and maintenance are not the same as subdivision upgrades
This is an important distinction for property owners and real estate agents. All properties require maintenance, regardless of whether they are cross lease or fee simple. Older stormwater systems may become blocked, damaged or difficult to access. These issues may need attention as part of normal property ownership.
A blocked pipe is a maintenance issue. Changing a cross lease title to fee simple does not itself create that blockage.
Where drainage defects are discovered during a conversion investigation, the appropriate response will depend on the individual circumstances. The Environment Court recognised that existing environmental effects do not necessarily arise from the subdivision simply because a title is being changed. Separate obligations relating to maintenance, unlawful discharges or other regulatory requirements can still apply independently of the conversion.
8. What this means for real estate agents
For agents, the message is straightforward.
Do not assume a cross lease property is too difficult or expensive to convert simply because the house, driveway or drainage system is old.
The April 2024 Environment Court decision has clarified important limits on the conditions Council may impose for qualifying controlled activity conversions. Agents should consider discussing conversion with vendors before marketing, particularly where:
That could make conversion a realistic option for more owners than agents previously believed.
9. Obtain a customised conversion quotation
Cross Lease Converter specialises in converting existing cross lease properties to fee simple for $19,900 plus GST per flat/new title. We also offer an accelerated process under which suitable properties may be market-ready for sale as fee simple in approximately five working days, with settlement arranged for when the new titles issue.
Agents can obtain a customised quotation at: https://www.crossleaseconverter.nz/
The quotation includes the registered proprietors' names, legal descriptions, title references, pricing and conversion process information. It can be provided to vendors or included in a property appraisal or marketing information memorandum.
10. The important message
Older dwellings, driveways and drainage systems should not automatically prevent an owner from investigating conversion to fee simple.
Before advising a vendor that conversion will require expensive infrastructure upgrades, obtain a property-specific assessment.
The answer may be considerably simpler than expected.

How Auckland real estate agents can identify new clients and generate potential listings from their existing database.
By Brent Clode
Article 3 in our ongoing series for real estate professionals on cross leases, property values, subdivision law and marketing opportunities.
1. The opportunity hiding in your database
Auckland has approximately 99,000 cross lease titles, representing a significant and often overlooked opportunity for real estate agents and their clients.
Many of these properties involve just two dwellings on a single underlying parcel of land, with each owner holding a cross lease title.
For agents, the opportunity is not just to identify an existing cross lease owner. It is to establish relationships with both owners and discuss the potential benefits of converting their properties to fee simple.
One existing client could lead to another client, two potential conversions and two future listings.
2. Try this simple PropertySmarts search
Many Auckland real estate agents use PropertySmarts for property research, appraisals and prospecting.
Here's a simple exercise worth trying in your farming area or existing client database.
Open PropertySmarts and set BOTH land-area search filters to 0 m².
This can help identify properties recorded without an individual land area, including potential cross lease properties.
Review the search results and confirm the title type of the properties identified.
Now compare these properties with the contacts already held in your agency database.
You may be surprised how many cross lease owners you already know.
3. Your existing client may know the neighbouring owner
Let's assume your search identifies a typical two-dwelling cross lease property.
You discover that one of the owners is already in your database, perhaps from a previous sale, appraisal or enquiry.
That existing client may already have the neighbouring cross lease owner's name and contact details.
Cross lease owners frequently know each other because of shared driveways, maintenance arrangements, insurance matters or other common property interests.
Rather than relying entirely on cold calling or door-knocking, ask your existing client whether they would be happy to introduce you to their neighbour.
You now have a natural reason to discuss something that could benefit both property owners.
Converting both cross lease titles to fee simple may improve the marketability and potential value of their respective properties.
And neither owner needs to be considering an immediate sale.
4. Generate a customised conversion quotation before making contact
This is where the opportunity becomes particularly practical.
Visit https://www.crossleaseconverter.nz/ and generate a customised cross lease to fee simple conversion quotation for the property.
The quotation provides property-specific information, including:
This gives agents something substantial to present to their existing client and, through an appropriate introduction, the neighbouring owner.
Rather than simply suggesting that conversion might add value, you can present a customised quotation explaining the proposed process and cost.
The quotation can also be included in an appraisal or marketing information memorandum.
You have moved from a general conversation about property value to a specific proposal for the owners' properties.
5. Two owners — two potential future listings
The commercial opportunity for agents is straightforward.
Your existing database contact becomes the starting point for two possible future client relationships.
The first owner already knows you.
The second owner may be introduced by their neighbour.
Both owners may have an interest in understanding the advantages of conversion.
Both may benefit from independent appraisals showing how their properties could be marketed as fee simple.
And both may eventually become vendors.
Even if neither owner intends to sell immediately, the agent has provided useful information and established a reason to maintain contact.
Consider the potential outcome:
One database search.
One existing client.
One neighbouring owner.
Two potential fee simple conversions.
Two possible future sale listings.
This is an opportunity that could already exist in your client database.
6. What does conversion cost?
Cross Lease Converter specializes in converting existing, lawfully established cross lease properties to fee simple.
For qualifying standard conversions where no alterations to the existing lawful dwellings, drainage or driveways are required, our published fixed price is:
$19,900 plus GST per flat/new title.
We also offer an accelerated process under which suitable properties can be market-ready for sale as fee simple in approximately five working days, with settlement on the new titles issuing.
Actual eligibility, requirements and timing depend on the individual property.
Importantly, converting an existing cross lease does not necessarily require the construction of additional dwellings or major physical changes to the property.

Here is your prospecting opportunity:
Remember: You don't need to wait for an owner to decide to sell before starting the conversation about increasing their property's value.

What McDonnell v Auckland Council means for property professionals
By Brent Clode
1. Why this case matters
CrossLeaseConverter.nz funded and were successful in McDonnell & Mackenzie v Auckland Council [2024] NZEnvC 076, the Environment Court delivered one of the most important rulings to date on cross-lease to fee simple conversions link to McDonnell.
The Court overturned Council-imposed engineering conditions, confirmed the limited scope of Council powers, and held that a cross-lease conversion is largely a paper exercise that does not allow Council to reassess the adequacy or condition of existing private services.
This decision protects thousands of Auckland homeowners from unnecessary and expensive Council requirements.
2. The core dispute
The owners at 86/86A Michaels Avenue applied to convert their two cross-lease titles into two fee-simple lots—no new buildings, no new development, no intensification.
Council treated the application as a controlled activity (E38.4.1(A3)), but then imposed two engineering conditions requiring the owners to prove:
The applicants appealed.
3. What the Environment Court decided
A. Council went beyond its powers
The Court held that for a controlled activity cross-lease conversion:
Key quote:
The AUP’s standards “relate to the location of infrastructure and not the functionality of stormwater and wastewater pipes.” (paras [29]–[31])
B. Cross-lease conversions do not create environmental effects
Since no new development occurs:
The Court agreed with both engineering experts that a conversion is “in effect a paper exercise”. (para [59])
C. Conditions 8 & 9 were unlawful
The Court deleted both conditions because:
Outcome: Appeal allowed. Conditions 8 and 9 cancelled.
4. What this means for cross-lease owners
✔ Council cannot require:
✔ Council can require:
✔ The existing buildings and services are accepted as-is, provided they were:
5. Why this decision is a game-changer for agents
Real estate agents advising cross-lease owners can now confidently say:
This reduces cost barriers and uncertainty for thousands of cross-lease homeowners—and makes fee-simple title uplift much more accessible.
6. Practical takeaways for the industry
For listing agents
Use this decision to encourage owners of cross-lease homes to consider conversion prior to marketing—fee simple titles consistently attract a higher buyer pool.
For buyers’ agents
Highlight to purchasers that fee simple conversions are now more predictable, with less engineering risk.
7. Looking ahead (relation to Article 1)
This case follows the principle emphasized in Hall v Geary (Article 1):
Council cannot use cross-lease conversions as opportunities to reassess unrelated compliance matters.
When the physical environment does not change, the legal assessment should not expand.

What the Hall v Geary High Court decision — and recent media coverage — means for your vendors and buyers
By Brent Clode
This document constitutes Article 1 in an ongoing series designed for real estate professionals, focusing on cross-leases, unit titles, and subdivision law and practice.
1. Why this matters
The recent High Court case, Hall v Geary [2025] NZHC 1004, and media attention link to NZ Post article have exposed major risks with cross-leases. Cross-lease titles are more restrictive and legally unstable than many realize, impacting about 20% or 214,000 of New Zealand’s homes.
2. Summary of Hall v Geary
The case concerned a large swim-spa installed in an exclusive-use yard of a cross-lease property, which a neighbour found visually intrusive.
Industry warning: Without co-lessor consent, structures may be removed by court order and can attract high remedy and legal costs, in this case about $150,000.
3. What counts as a “structure”?
According to Hall v Geary and case law, items like spa and swimming pools, sheds, cabins, retaining walls, decks, pergolas, air-conditioning units, solar panels, fences, large shades, or any noticeable semi-permanent structures all require unanimous consent. Installing these without co-lessor or landlord consent may create future legal issues for owners.
