A property title number is the unique reference used to identify a record of title. You may find it on an existing title, sale document, rates record or property file, but an address alone is not always enough: one street address can cover several titles, and a recent subdivision may have created new references.
Every property in New Zealand has a unique title number — a reference that links your land to its official legal record. Whether you're buying, selling, refinancing, or simply doing your due diligence, knowing how to find this number is an essential first step in any property transaction.
This guide explains exactly what a property title number is, where to find it, and why it matters.
What Is a Property Title Number?
A property title number (also called a certificate of title number or record of title number) is the unique identifier assigned to a parcel of land when it's registered in New Zealand's official land register. It's the key that unlocks all the recorded information about a property — who owns it, what encumbrances exist, any covenants or easements, and the legal boundaries.
Think of it like a passport number for your property. Once you have it, you can retrieve the full official record in seconds.
The format is typically a combination of letters and numbers, such as NA123/456 or SA12B/789. The prefix indicates the land registry office where the title was originally issued:
- NA — Northern (Auckland area)
- SA — South Auckland
- WN — Wellington
- CB — Canterbury/Westland
- OT — Otago/Southland
Where to Find Your Property Title Number
1. On Your Existing Title Documents
If you've previously purchased the property, your settlement documents will include a copy of the record of title. The title number appears prominently at the top of the document. Check your conveyancing paperwork, or look in the files your solicitor provided at the time of settlement.
2. On Your Council Rates Notice
Your annual rates notice from your local council often includes the legal description of your property, which may include the title reference or allow you to cross-reference it. Look for fields labelled "legal description," "certificate of title," or "title reference."
3. Through a Property Title Search
The fastest and most reliable way to find a property title number — especially for a property you don't yet own — is through an official title search. You can run a title search by address on our home page and get the official record back by email. Our Record of Title search provides the current title document, which includes the title number, owner details, and any registered interests on the land.
4. Via Your Mortgage Documents
If you have a mortgage on the property, the loan documents will reference the property's title number. Your bank or lender used it when registering the mortgage against the title. Check your mortgage deed or any property security documents.
5. Through Your Solicitor or Conveyancer
Your lawyer who handled the purchase will have retained copies of all title documents. A quick email or phone call should get you the title number quickly. Solicitors are required to keep property transaction records, so this is a reliable fallback.
6. From a Real Estate Listing
Many real estate agent listings — particularly those on Trade Me Property or realestate.co.nz — include the legal description or title reference in the listing details. This is especially common for commercial properties and bare land.
Why the Title Number Matters
The title number isn't just an administrative reference. It's the foundation of property ownership in New Zealand. Here's why knowing it matters:
Verifying Ownership
Before entering into any agreement to buy or sell property, you should confirm that the person you're dealing with actually owns it. A current Record of Title confirms the registered owner's name and whether there are any other interests (such as mortgages or caveats) on the property. The same search lets you find out who owns a property in New Zealand before you commit to a purchase.
Checking for Encumbrances
The title number gives you access to every registered encumbrance — mortgages, caveats, easements, and covenants. Understanding what's attached to a property before you commit to purchasing it can save you from costly surprises. A Pre-Purchase Package gives you a comprehensive picture of everything registered against the property.
Refinancing or Lending
Banks and lenders always require the title number when processing a mortgage or refinancing application. Having it ready speeds up the process significantly.
Resolving Boundary Disputes
If there's a dispute about where your property ends and a neighbour's begins, the title number is the starting point for retrieving the official survey plan. Our Survey Plan search gives you the legal boundaries as registered.
What if the Title Number Has Changed?
In some circumstances, a property's title number may change. This can happen when:
- A subdivision creates new titles from an existing parcel
- Titles are amalgamated (two or more parcels merged into one)
- Older "limited" titles are converted to standard titles
- A unit title scheme is established on the land
If you're working from an older title number and can't find the current record, a Historical Title search can help trace the chain of ownership and show when and why title numbers changed.
How to Get the Full Title Document
Once you have the title number, getting the complete official document is straightforward. Our search service lets you order:
- Record of Title with Diagram: The current title document showing ownership, legal description, diagram, and all registered interests
- Guaranteed Search: A snapshot of the title that's legally guaranteed as accurate at the time of issue — used in settlements and legal proceedings
- Historical Title: Prior title documents showing the ownership history
Results are typically delivered within 1–2 hours during business hours.
Using the Title Number for Due Diligence
If you're purchasing a property, the title number should be your first search. Before you make any offer, consider:
- Order a current Record of Title — confirm ownership and check for any unexpected encumbrances
- Check the diagram — verify the shape and dimensions match what you've been shown
- Order instruments if needed — any easement, covenant, or mortgage document can be retrieved as a separate Instrument
- Consider a Pre-Purchase Package — if you want everything in one go, our Pre-Purchase Package includes title, survey plan, and instruments
Practical process
- Collect the full street address, unit number, legal description and any existing title reference shown on property documents.
- Check whether the address represents one title, multiple titles, a unit development or a cross-lease arrangement before choosing a reference.
- Order the current record for the matched reference and confirm the owners, estate, legal description and diagram relate to the intended property.
Decision guide
| Situation | Next step |
|---|---|
| You have an old title reference | Use it as a lead, then verify that it has not been replaced by subdivision, amalgamation or a later title. |
| The address returns several possible titles | Compare unit, lot, deposited plan and estate details instead of selecting the first result. |
| No address match is reliable | Use the legal description, parcel context or professional assistance to identify the correct record. |
Common mistakes and risks
- Treating a street address as a legal identifier when it may cover more than one title.
- Reusing a historic reference without checking whether a new title has been issued.
- Ordering a record before confirming the unit, lot and plan details.
Key takeaways
- The title number identifies the legal record, while the address is only a search clue.
- Multiple-title and newly subdivided properties need an extra matching step.
- Confirm the legal description and estate before relying on the document.

Frequently Asked Questions
Can I find a property title number for free?
Some public information (such as council rates details) may help you identify a property, but obtaining the full official title document requires a paid search. The Register itself is maintained by New Zealand's official land registry and is not freely searchable online. Our Record of Title search is the most direct way to get the complete document.
What if I only have the street address, not the title number?
That's completely fine. You can order a title search using just the street address. Our system matches the address to the correct title in the register and retrieves the document for you.
How current is the title number information?
The title register is updated in real time. When you order a Guaranteed Search, you receive a legally guaranteed snapshot of the title at that exact moment — including any dealings that were registered minutes before your search.
What a title reference actually looks like (old versus new format)
Converted references from older titles carry a two-letter land-district prefix followed by numbers and sometimes a letter, for example WN1A/1 or NA123/456. The prefix marks the land district the title was first registered in. Newer titles created after the register moved online are generally numbers only, with no prefix. You may see the same identifier called a certificate of title, a computer register, or a record of title depending on its age; "record of title" is the current term. Either style works when you order a search, and if yours has a slash, type it exactly as it appears.
How to find your title number by address, step by step
- Write down the full property address as it appears on official mail, including any unit or flat number.
- Confirm you have the right property. Where several units or subdivided lots share one street address, note the unit or flat letter, because one address can map to more than one title.
- Run an address-based title search. New Zealand's official land registry matches the address to the correct title and returns the current record of title.
- Read the reference off the returned record. It appears in the header, including any prefix letters and the slash.
- If more than one title comes back, match on the legal description, the lot and deposited plan number, to identify the parcel you mean.
Where the title reference hides on documents you already have
Before paying for a search, check paperwork you may already hold. Look for the words "title reference", "record of title", "certificate of title", or "legal description".
- Council rates notice: usually carries the legal description, often near the property description block.
- Sale and purchase agreement: the legal description is in the property details near the front.
- LIM report: commonly states the legal description and title reference near the beginning.
- Mortgage or loan documents: your lender registered its interest, so the reference is usually quoted.
- Earlier settlement pack: the record of title shows the reference at the top.
If a document only shows a legal description, for example "Lot 3 DP 12345", that is still enough to identify the correct title when you run a search.
Turning the title number into the full record of title
The title number is the key; the full record of title is what it unlocks: the legal description and area, the registered owners and how they hold the land, the estate or tenure, and any registered interests such as mortgages, easements, covenants or caveats. Supply either the reference or the address to New Zealand's official land registry, or a service that draws from it, confirm the correct parcel using the legal description, and request the current record of title.
What does a New Zealand title reference look like?
Older converted titles use a two-letter prefix plus numbers and sometimes a letter, such as WN1A/1; newer titles are generally numbers only. Both work when you order a search.
Can one address have more than one title number?
Yes. Cross-lease flats, unit-title developments and recent subdivisions can share a street address while sitting on separate titles. Match on the legal description to be sure.
I only have the legal description, not the title number. Is that enough?
Yes. A legal description such as "Lot 3 DP 12345" identifies the parcel and can be used to locate the correct title.
Is the title reference the same as the legal description?
No. The reference is a short identifier for the record; the legal description describes the parcel, including the lot, deposited plan and area. A record of title shows both.
Why do some documents say "certificate of title" and others "record of title"?
They refer to the same record at different times. "Record of title" is the current term; older documents may say "certificate of title" or "computer register".
