Converting a cross lease to fee simple titles: the council process

A cross lease title can feel like a lesser kind of ownership. Each owner holds a share of the whole site and a long lease of their own flat, and almost anything done to the buildings needs the agreement of the neighbours. Converting the title into separate fee simple lots gives each owner a title of their own. This note outlines how that conversion works, with particular reference to Auckland Council and the Auckland Unitary Plan. It sets out the sequence of steps, the statutory provisions engaged, and the points at which conversions most often run into difficulty.

This note is general information only. It is not legal advice and it does not deal with the circumstances of any particular site. Anyone considering a conversion should take advice from a lawyer and a surveyor.

The legislative setting

The Planning Bill and the Natural Environment Bill passed their third readings on 22 September 2026. The transition period under the new legislation runs for several years, and in the meantime the Resource Management Act 1991 (RMA), including the subdivision provisions in Part 10, continues to apply to subdivision consents and survey plans. The Auckland Unitary Plan (Operative in Part) remains the operative plan. This note is therefore framed under the RMA and the Unitary Plan as they currently stand. References to section numbers are to the RMA unless otherwise stated.

What a cross lease is, and why conversion is a subdivision

A cross lease title comprises two things. The first is a fee simple estate in the underlying land, held by all of the flat owners together as tenants in common in undivided shares. The second is a registered lease of each flat and any restricted use area, typically for a term of 999 years, granted by all of the co-owners to the owner of that flat and shown on a deposited flats plan.

Converting the title into separate fee simple lots is a subdivision within the meaning of s 218, because it divides the existing allotment into new allotments by the deposit of a survey plan. Section 11 prohibits the subdivision of land unless it is expressly allowed by a resource consent or a rule in a plan. A conversion therefore cannot be registered without a subdivision consent and the certificates the council later issues under ss 223 and 224.

The process has three distinct legs:

• the council leg, which is the resource consent;
• the survey leg, in which the council is again involved at the certification stages; and
• the Land Information New Zealand (LINZ) registration leg, in which the leases are surrendered and new titles issue. That leg is handled by the solicitor and the surveyor.

Before any application is made

Title investigation. The solicitor obtains the record of title for each flat, the flats plan, the registered lease instruments, and all encumbrances: mortgages, easements, land covenants and consent notices. The lease terms matter because they govern the consent rights between the owners. The mortgages matter because every mortgagee must later consent to the surrender of the leases and the issue of new titles.

Defective cross leases. If the buildings on the ground do not match the flats plan, the cross lease is defective. Common examples are an extension, a conservatory or a carport built after the flats plan was deposited. The conversion will cure the defect, but the council will want to know whether those works were lawfully established. That question affects the activity status of the application and the final s 224(c) stage, both discussed below.

Agreement of all owners. All registered proprietors of the fee simple estate must join in the application and in the later dealings, as must every mortgagee at the registration stage. A single owner who will not participate stalls the process. Where agreement cannot be reached, the remaining avenue is an application to the High Court under s 339 of the Property Law Act 2007 for an order dividing the property among the co-owners, or compelling the steps needed to give effect to a division.

A licensed cadastral surveyor. The surveyor prepares the scheme plan for the council, carries out the cadastral survey, and lodges the Land Transfer plan in Landonline. In practice the surveyor, or a planner working with the surveyor, usually prepares and lodges the resource consent application as well.

Pre-application engagement. Auckland Council offers pre-application meetings, for which it charges. For a straightforward conversion a meeting is often unnecessary. It is worthwhile where there are non-complying buildings, shared services, flooding or overland flow paths, or notable trees on the site.

The Auckland Unitary Plan framework

Activity status. The subdivision rules are in Chapter E38 (Subdivision - Urban) for land in the residential and business zones, and Chapter E39 (Subdivision - Rural) for rural land. Table E38.4.1, which applies across all zones, makes the conversion of a cross lease to a fee simple title a controlled activity (row A3). Cross lease, company lease, unit title and strata title subdivision is also a controlled activity (row A4). A controlled activity must be granted consent, although the council may impose conditions on the matters over which it has reserved control.

The conversion standard. Controlled activity status depends on compliance with Standard E38.7.2.2 (conversion of cross lease to fee simple). In summary, that standard requires that all existing development on the site either complies with the overlay, Auckland-wide and zone rules, or has existing use rights, or is authorised by a resource consent, or holds a building consent, code compliance certificate or certificate of acceptance as the case requires. It also requires service connections to be located within the site they serve. Where the standard is not met, the subdivision does not qualify under row A3 and is assessed instead as a discretionary activity under row A13. The practical consequence is that any non-compliance should be resolved before, or at the same time as, the subdivision application, so that the controlled activity pathway stays available.

Matters of control. These are set out in E38.11.1. They include compliance with any approved resource consent; the effects of the site design, size, shape, gradient and location, including how existing buildings, manoeuvring areas and outdoor living spaces relate to the proposed boundaries; the provision of infrastructure; and effects on historic heritage and cultural heritage items.

Minimum site sizes. The minimum net site area standards that govern vacant site subdivision in the residential zones do not apply in the same way to a conversion, or to subdivision around existing lawfully established dwellings. That is why conversions on small sites are achievable. Each new lot is instead assessed for whether the dwelling and its curtilage can function as a self-contained site.

New boundaries create new standards. This is the point most often overlooked. On conversion, the notional boundaries between the flats become real site boundaries. Buildings that complied with the land use standards when measured from the outer boundaries of the parent site may infringe the yard, height in relation to boundary, outlook, building coverage or impervious area standards when measured from the new internal boundaries. The council assesses the existing buildings against the zone standards as if the new lots already existed. Any infringement must be authorised by a land use consent, applied for at the same time as or before the subdivision consent, in order to satisfy Standard E38.7.2.2. Existing use rights under s 10 do not help, because the boundary from which the standard is measured is new.

Lawfully established buildings. The council checks the property file for building consents and code compliance certificates for every structure on the site. Work done without consent may need a certificate of acceptance under s 96 of the Building Act 2004 or, for minor work, confirmation that it was exempt under Schedule 1 of that Act. The council will not ordinarily issue its s 224(c) certificate while significant unconsented work remains unresolved.

Other overlays and controls. These include flooding and overland flow paths (shown on the council's GIS viewer), coastal and natural hazard overlays, notable and protected trees, historic heritage and special character overlays, and any site-specific precinct provisions. The national environmental standard for contaminants in soil is not usually engaged by a conversion that involves no earthworks, but that should be confirmed.

The subdivision consent application

The application is made under s 88 on the council's prescribed form and must include the information required by Schedule 4. That includes an assessment of environmental effects in a level of detail that matches the scale and significance of the effects. For a controlled activity conversion the assessment is short, but it must address the matters of control in E38.11.1 and demonstrate compliance with Standard E38.7.2.2.

The core documents are:

• a scheme plan prepared by the surveyor, showing the parent site, the proposed lots and their areas, the existing buildings and their relationship to the new boundaries, existing and proposed easements, and vehicle access;
• the records of title and the flats plan;
• written confirmation that all registered proprietors join in the application;
• an assessment against the E38 activity table and standards, and against the zone land use standards for the existing buildings;
• a servicing assessment covering water supply, wastewater and stormwater for each lot, including whether the connections are separate or shared;
• a vehicle access assessment where the driveway is shared or crossings need to be formed or altered; and
• where triggered, a flooding or overland flow path assessment, a geotechnical statement, an arborist report or a heritage assessment.

Servicing is usually where the detail lies. Watercare generally requires each fee simple lot to have, or be capable of having, its own water and wastewater connection. Shared private drains crossing the new boundaries need easements, or at least rights to drain water and sewage recorded in the memorandum of easements. Healthy Waters, the council's stormwater unit, will want stormwater disposal confirmed for each lot. Where separate connections are physically required, they become a condition of consent and a cost of the project.

Council fees. Auckland Council charges a deposit on lodgement and then invoices its actual processing costs at hourly rates. There are separate fees for the s 223 and s 224 certifications, and for engineering plan approval where it is needed. Development contributions under the Local Government Act 2002 are assessed on the net increase in household unit equivalents. A conversion that creates no additional dwelling ordinarily attracts no development contribution, but the council issues an assessment in every case and it is worth checking.

How the council processes the application

Completeness check. Within 10 working days of lodgement the council decides under s 88(3) whether the application is complete. It may return the application if it does not include the information Schedule 4 requires. Lodgement is ordinarily electronic, through the council's online consenting portal.

Further information. The council may request further information under s 92. The statutory clock stops while a request is outstanding. The applicant may decline to provide the information, in which case the council may decline the application or notify it. Most delays in conversion applications come from s 92 requests about servicing, unconsented work, or the compliance of existing buildings with standards measured from the new boundaries.

Notification. The council decides under ss 95A to 95G whether the application is publicly notified, limited notified or non-notified. Cross lease conversions are almost always non-notified, because the adverse effects are no more than minor and there are no affected persons beyond the applicants themselves.

Substantive assessment. The council assesses the application under s 104 and, for a controlled activity, s 104A (or s 104B for a discretionary activity), and for subdivisions specifically under s 106. Section 106 allows the council to refuse consent, or to impose conditions, where the land is likely to suffer material damage from erosion, falling debris, subsidence, slippage or inundation, or where each lot lacks sufficient legal and physical access. Access is normally dealt with by reciprocal rights of way over the shared driveway.

Decision timeframe. For a non-notified application the council must issue its decision within 20 working days of lodgement under s 115, not counting any period during which a s 92 request is outstanding. In practice, allowing for s 92 requests, a conversion consent typically takes between one and three months from lodgement to decision.

Conditions of consent

The council imposes conditions under ss 108 and 220. Conditions commonly found on a conversion consent include:

• that the subdivision be carried out in accordance with the approved scheme plan;
• the creation of easements in favour of the relevant lots, such as rights of way, rights to convey water, electricity and telecommunications, and rights to drain water and sewage, shown on the Land Transfer plan and registered on deposit;
• party wall easements or covenants where the dwellings are attached;
• separate water and wastewater connections for each lot to Watercare's requirements;
• stormwater disposal arrangements for each lot;
• forming or upgrading vehicle crossings to the council's standards;
• engineering plan approval under the council's Code of Practice for Land Development and Subdivision, where physical works are required;
• that all existing cross leases be surrendered on deposit of the plan; and
• that all consented works be completed, or secured by bond under s 108(2)(b), before the s 224(c) certificate issues.

Consent notices. Where a condition is ongoing, the council will require it to be recorded in a consent notice under s 221. Examples are a restriction on building within an overland flow path, an obligation to maintain a stormwater device, or a requirement that buildings on a lot comply with a specified standard. The consent notice is registered against the new titles and binds later owners.

Amalgamation conditions. If part of the parent site is to be held with another title, or a lot is to be held in common, the council may impose an amalgamation condition under s 220(1)(b)(iii). That condition is given effect under ss 224(f) and 241.

Lapse periods

The subdivision consent lapses under s 125 if the survey plan is not submitted to the council for approval under s 223 within five years of the consent commencing. An extension of that period may be sought under s 125(1A). Once s 223 approval has been given, the plan must be lodged for deposit with LINZ within three years, failing which the s 223 approval lapses (s 224(h)).

Survey and certification

Cadastral survey. After consent is granted, the surveyor carries out the field survey and defines the new boundaries. Those will ordinarily follow the outlines on the flats plan, adjusted where the actual buildings differ. The surveyor prepares the Land Transfer plan in Landonline in accordance with the Cadastral Survey Act 2002 and the Cadastral Survey Rules, together with the memorandum of easements and any schedule of land covenants to be registered on deposit.

Section 223 approval. The surveyor submits the Land Transfer plan to the council and asks for approval under s 223. Within 10 working days the council must certify that the plan conforms with the subdivision consent, including as to the lots, the easements and any amalgamation condition, and that the lapse period has not expired.

Section 224(c) certificate. Separately, the applicant must satisfy the council that every condition of the consent has been complied with, or has been secured by bond or completion certificate under s 224(e). The council inspects where physical works were required, checks the Watercare and Healthy Waters sign-offs, confirms that fees and any development contributions have been paid, and confirms that any consent notice is in order for registration. It then issues its certificate under s 224(c). Where unconsented building work was identified during processing, the council will usually want the certificate of acceptance, or confirmation of exemption, in hand first. A conversion involving no physical works can obtain the s 223 approval and the s 224(c) certificate at or about the same time.

Registration with LINZ

The solicitor prepares an e-dealing in Landonline. In the usual order, it comprises:

• the deposit of the Land Transfer plan, with the s 223 and s 224(c) certificates attached;
• the surrender of each cross lease by all of the lessees and co-owners, with the consent of every mortgagee;
• transfers between the co-owners so that each new fee simple lot vests in the owner of the corresponding flat. Because the owners hold undivided shares in the whole of the parent site, a partition by transfer is needed;
• the creation of the easements and covenants scheduled on the plan;
• the registration of any s 221 consent notice; and
• the re-registration or variation of each mortgage so that it attaches to the new lot.

New records of title then issue for each lot.

Mortgagee consent. The mortgagee of each flat must consent to the surrender of the lease, because the surrender extinguishes its security, and will require its mortgage to attach to the new fee simple title. Lenders commonly require a certificate from their own solicitor and charge a fee for giving consent.

After deposit. The council updates its rating database so that each lot becomes a separate rating unit, and Watercare updates its billing accounts. The owners should also tell their insurers, because the insured interest changes from a leasehold flat to a fee simple lot.

Tax. A conversion does not ordinarily involve any change in beneficial ownership, and Inland Revenue's position is that a title conversion of this kind is not a disposal for bright-line purposes. That should still be confirmed with a tax adviser for the particular owners before the transfers are registered.

Indicative timing and cost

A straightforward conversion involving no physical works typically takes four to eight months from engaging the surveyor to the issue of the new titles. Roughly, that is one to three months for the council consent; two to four months for the survey and the s 223 and s 224 certification, which can overlap to some extent with consent processing; and four to eight weeks for the registration leg, including obtaining mortgagee consents. Separate servicing works, vehicle crossings, land use consents or unconsented building issues can add months.

The principal costs are:

• the surveyor's fees for the scheme plan, cadastral survey and Land Transfer plan;
• the council's consent processing fees (the deposit plus actual costs), the s 223 and s 224 fees, and any engineering plan approval fees;
• Watercare and Healthy Waters costs if new connections are needed;
• LINZ lodgement fees;
• mortgagee consent fees; and
• legal fees for the application and the registration leg.

Indicative all-in costs for an uncomplicated two-flat conversion are commonly quoted in a range from several thousand dollars to the low tens of thousands of dollars, divided between the owners. The figure rises sharply where physical works or land use consents are needed.

Common complications

The problems that most often derail or delay a conversion are:

• one owner refusing to participate;
• existing buildings infringing standards measured from the new boundaries, which calls for a land use consent alongside the subdivision consent in order to satisfy Standard E38.7.2.2;
• unconsented building work;
• shared private drains, or a single water connection serving more than one flat;
• buildings or structures encroaching across the proposed new boundaries, which means adjusting the boundaries or creating encroachment easements;
• overland flow paths or flood plains crossing a lot, which attract consent notices or building restrictions; and
• notable trees whose protected root zones straddle the new boundaries.

Most of these can be identified at the start, from the title, the flats plan, the council property file and the GIS viewer. Doing that work before anything is lodged is usually the single best way to keep a conversion on the controlled activity pathway and on time.
