Cross-lease in New Zealand: what it means and how it changes
LINZ records 210,171 live cross-lease titles, 8.7% of all live property titles in New Zealand. They sit on about 87,651 shared sections.
What a cross-lease is
A cross-lease owner holds two things: a share of the whole section, held together with the other owners, and a lease of their own flat from the other owners. Leases are usually for 999 years at a nominal rent, such as 10 cents a year, which is usually not collected. The title usually includes a flats plan (some older titles do not) showing each flat, any areas for one owner's exclusive use, such as a garden, and the shared areas. A flat's lease area can include attached structures and ancillary buildings such as garages and sheds.
Changes to the exclusive-use areas or shared areas usually must be agreed by all or a majority of the owners. Depending on the lease terms, the other owners' consent may also be needed for things like painting the outside, building a deck or putting up a fence.
Cross-lease, freehold and unit title
| Freehold | Cross-lease | Unit title | |
|---|---|---|---|
| What you own | Generally, your own piece of land and what is on it, subject to any interests on the title | A share of the whole section, plus a lease of your flat | Your unit, plus a share of the common property |
| Who decides on changes | You, within council rules and any covenants or easements | All or a majority of the owners, under the lease terms | The body corporate: most day-to-day decisions by its committee or 50% or more of owners, some by 75% or more |
| Plan on the title | Survey plan of the land | Flats plan | Unit plan |
When the flats plan no longer matches
LINZ explains that a cross-lease title can become defective when a flat is altered or added to and the flats plan is not updated. A defect does not by itself create a legal obligation to update the plan, and many plans do not match what is built. The mismatch is most often found when the property is put up for sale, and an updated plan may be needed before the sale can be completed.
Updating a flats plan to change or add lease areas counts as a subdivision and needs subdivision consent from the council. A building consent for the alteration does not update the title on its own.
Converting a cross-lease to freehold
Converting cross-lease flats into separate freehold titles is a fee simple subdivision under the Resource Management Act, so it needs subdivision consent from the council (Environment Court, Re McKay [2018] NZEnvC 180). LINZ lists the main hurdles as getting consent and agreeing costs with all the co-owners and their mortgagees, possible extra servicing and Building Code work, and higher surveying, legal and council fees. LINZ's list of fees reflects who is involved: a surveyor, a lawyer and the council.
Owners can instead convert to unit titles under the Unit Titles Act 2010. LINZ says that route needs a special resolution passed by 75% of the members (the owners) or a High Court order.
The official sources linked here do not give typical conversion costs. They depend on the section, the council and the work needed, so get quotes from a surveyor and a lawyer.
How New Zealand's cross-leases are set up
New Zealand's cross-lease titles belong to 87,651 schemes (shared sections). 76% are two-flat schemes, 12% have three flats and 11% have four or more, up to 65 on one section.
The typical shared section is 908 m², about 408 m² of land per flat.
Half of these schemes have their earliest current title issued in or before 1988.

| Cross-lease schemes (shared sections) | 87,651 |
| Two-flat schemes | 76.2% |
| Three-flat schemes | 12.2% |
| Four or more flats | 11.4% |
| Typical section size (from the titles, not a survey) | 908 m² |
| Typical land per flat | 408 m² |
| Schemes with a garage written into a lease | 28.4% |
| Schemes with a carport in a lease | 13.3% |
| Schemes with a separate exclusive-use area | 4.5% |
| Schemes referring to more than one flats plan (usually redrawn; not by itself a problem) | 35.6% |
| Median year of earliest current title | 1988 |
| Two-flat schemes on 700 m² or more | 54,978 |

Questions
What does cross-lease mean?
Each owner holds a share of the whole section together with the other owners, and a lease of their own flat from the others, usually for 999 years at a nominal rent. The flats plan on the title shows each flat, any exclusive-use areas and the shared areas.
Is a cross-lease the same as freehold?
No. A freehold (fee simple) owner generally owns their own piece of land and what is on it, subject to any interests in it, registered or not. A cross-lease owner owns an undivided share of the land with the other owners plus a lease of their flat, and changes to the flats or shared areas need the other owners' agreement under the lease terms.
Can a cross-lease be converted to freehold?
It can be converted through a fee simple subdivision, which needs subdivision consent from the council. LINZ describes the main hurdles as getting consent and agreeing costs with all the co-owners and their mortgagees, possible servicing and Building Code work, and surveying, legal and council fees. The official sources linked here do not give typical costs.
What is a defective cross-lease title?
LINZ uses the term when a flat has been altered or added to and the flats plan no longer matches what is built. LINZ notes that a defect does not by itself create a legal obligation to update the plan, but the mismatch often comes up when the property is sold, and updating the lease areas is a subdivision that needs subdivision consent.
