To change your name after marriage in New Zealand, you generally do not need a formal deed poll. Instead, you can assume your partner’s surname by using your official marriage certificate as primary evidence. You must then individually update your identity documents, such as your driver licence and passport, with the respective government agencies to formalize the change.
Getting married or entering a civil union marks a significant chapter in your life, often accompanied by the decision to change your surname. In New Zealand, the landscape of changing your name is distinct from many other jurisdictions. It offers flexibility but requires a proactive approach to administration. Whether you wish to take your partner’s name, hyphenate both names, or create a new family name, understanding the correct administrative path is crucial to avoiding bureaucratic headaches.
This comprehensive guide details exactly how to navigate the maze of government departments, banks, and legal entities to ensure your new identity is recognized across the board.
Understanding the Process: Assuming a Name vs. Legal Change
One of the most common misconceptions among newlyweds in New Zealand is that they must legally change their name via a “Deed Poll” to adopt their spouse’s surname. For the vast majority of couples, this is incorrect. New Zealand law operates on a convention of “usage,” meaning you are free to call yourself by a new name as long as there is no fraudulent intent.
Option 1: Assuming a Name (The Standard Route)
If you intend to take your spouse’s surname or hyphenate your two surnames (e.g., Smith-Jones), you are simply “assuming” a name. This is not a change of legal identity but rather a change in how you are addressed and identified on documents.
In this scenario, your birth certificate remains unchanged. Your marriage certificate or civil union certificate acts as the “bridge” document linking your birth name to your married name. You present this bridge document to agencies like Waka Kotahi (NZ Transport Agency) and the Department of Internal Affairs (DIA) to update your records.
Option 2: Legal Name Change by Deed Poll
A formal name change by Deed Poll is only necessary if you are creating a name that cannot be directly derived from the marriage. For example:
- You and your partner want to mash your names together to create a brand new surname (e.g., Smith and Jones becoming “Smones”).
- You want to move your maiden name to become a middle name.
- You want to change your first name entirely.
If you fall into this category, you must apply to the Department of Internal Affairs to formally change your name. This costs approximately $170 NZD and results in a new birth certificate (if born in NZ) or a name change certificate.
The Golden Ticket: Your Official Marriage Certificate
Before you can change your name with any organization, you must possess the correct documentation. The decorative certificate you signed on your wedding day is usually just a ceremonial document and is rarely accepted for official identification purposes.
You need the Official Marriage Certificate issued by Births, Deaths and Marriages (BDM). If you did not order this when you applied for your marriage licence, you can order one online after the marriage has been registered by your celebrant.
Warning regarding the “Copy of Particulars”: Sometimes couples receive a “Copy of Particulars of Marriage.” While this contains the legal details, some banks and strict government agencies (like the Passport Office) prefer the standard Official Marriage Certificate. It is advisable to order the standard certificate to ensure smooth processing across all entities.
According to Govt.nz, you should wait until your celebrant has registered the marriage (usually within 10 days of the ceremony) before applying for your certificate.
Updating Your Primary Identification Documents
Once your marriage certificate arrives in the post, the real work begins. You cannot update everything at once; there is a hierarchy of documents. You should prioritize your photo ID first, as other institutions (like banks) will require updated photo ID to process their changes.
New Zealand Driver Licence
Waka Kotahi (NZ Transport Agency) is often the easiest place to start. You cannot do this online; you must visit a driver licensing agent (usually an AA Centre or VTNZ).
You will need to:
- Complete the application form (DL1).
- Present your current driver licence.
- Present your original Marriage Certificate (or a certified copy).
- Pay the replacement licence fee (approximately $38.20 NZD, subject to change).
They will take a new photo and signature. Your new licence will arrive in the mail within 7–21 days.
New Zealand Passport
Updating your passport is a more significant expense but vital for international travel. If you have more than two years left on your current passport, you might choose to wait until it expires, provided you book all travel under your maiden name. Crucial Rule: The name on your airline ticket must match the name on your passport exactly.
To update your passport:
- Apply for a new passport online via the Department of Internal Affairs website.
- Upload a new passport photo.
- During the application, you will be asked if you have changed your name. Select “Yes” and provide the details of your marriage. Because the DIA manages both passports and marriage registrations, they can often verify your marriage internally without you needing to mail the physical certificate, provided the marriage occurred in New Zealand.
RealMe Verified Identity
If you have a RealMe Verified Identity, you should update this after your passport or citizenship details are updated. This allows you to log in to government services (like IRD and Companies Office) with your new identity. You can instigate a name change via the RealMe dashboard, which will verify your details against the BDM register.
Notifying Government Agencies and Financial Institutions
With your new photo ID in hand, you can now tackle the wider list of organizations. Do not assume these agencies speak to each other; they generally do not.
Inland Revenue (IRD)
Updating your name with the IRD is essential for your tax records and KiwiSaver. This can be done easily via myIR Secure Online Services.
- Log in to myIR.
- Go to “More” > “My details” > “Update name”.
- You may be required to upload a scanned copy of your marriage certificate.
The Electoral Commission
To ensure you can vote under your new name, you must update your details on the electoral roll. This can be done online at vote.nz using your RealMe login or your driver licence number to verify the change.
Banks and Financial Institutions
Banks have strict Anti-Money Laundering (AML) obligations. You generally cannot update your name over the phone or online. You must visit your local branch in person.
Bring with you:
- Your original Marriage Certificate.
- Your new Driver Licence or Passport (showing the new name).
- Your old bank card.
While you are there, ensure they update your credit cards and send new ones. Don’t forget to update your KiwiSaver provider if they are separate from your main bank.
Insurance, Utilities, and Health
This is the “long tail” of administration. Over the coming months, you will need to contact:
- Insurance: Car, House, Contents, and Life Insurance. This is critical—ensure your policy matches your legal name to avoid claim disputes.
- Utilities: Power, Internet, and Phone providers.
- Health: Visit your GP (General Practitioner) to have your name updated on the National Health Index (NHI). This ensures your prescriptions and hospital records are consistent.
Hyphenating, Double-Barrelling, and Cultural Considerations
In New Zealand’s diverse society, naming conventions are deeply personal and cultural.
Hyphenating (Double-Barrelling)
If you choose to hyphenate (e.g., Sarah Smith-Ngata), this is treated as “assuming” a name. You do not need a deed poll. You simply use the marriage certificate to prove the link between “Smith” and “Ngata.” However, you must be consistent. You cannot use “Smith-Ngata” on your licence and just “Ngata” on your passport. Government records must align.
Māori and Cultural Naming Customs
For many Māori, the surname carries the mana of the whakapapa (ancestry). Keeping one’s birth name is common, or the husband may take the wife’s name if her line carries specific chiefly status or land rights. The process remains the same regardless of who is changing their name; a husband taking a wife’s name or a same-sex partner taking the other’s name follows the exact same “assumption” process using the Civil Union or Marriage certificate.

Frequently Asked Questions
Below are answers to the most common queries regarding changing your name after marriage in New Zealand.
Do I have to legally change my name after marriage in NZ?
No, you do not have to legally change your name by deed poll. You can simply “assume” your partner’s name using your marriage certificate as proof. A deed poll is only required if you are creating a completely new name or moving names around (like making your maiden name a middle name).
How much does it cost to change my name after marriage?
The name change itself is free if you are assuming your spouse’s name. However, you will pay for updated documents. A new Driver Licence costs approx $38.20, and a new adult passport costs approx $215.00 (prices subject to change by NZ government).
Can I use my maiden name for work and married name for home?
Yes, you can. Many professionals keep their maiden name for their career to maintain their professional reputation while using their married name socially. However, your payroll usually needs to match your bank account and IRD records to avoid confusion.
How long does the name change process take?
The process depends on how quickly you apply for documents. A marriage certificate takes about 1-2 weeks to arrive. A driver licence takes up to 21 days, and a passport can take up to a month depending on processing times. Fully updating all agencies usually takes 1-2 months of admin.
What if I want to mesh our last names into a new one?
If you want to blend surnames (e.g., “Roberts” and “Gunn” becoming “Robunn”), this is considered a legal name change. You cannot use your marriage certificate for this. You must apply for a formal name change by Deed Poll with the Department of Internal Affairs.
Do I need to change my name on my birth certificate?
No. If you are assuming your spouse’s name, your birth certificate remains in your birth name. Your marriage certificate acts as the link between your birth name and your married name. Your birth certificate is only changed if you do a formal Deed Poll name change.
