Apostille or Authentication?

Do you also need an Apostille or Authentication?

Sometimes in addition to Notarisation an Apostille or Authentication may be required.

Apostille and Authentication are both methods of certifying New Zealand documents for overseas use, but the key difference lies in which countries accept them.

Always check with the receiving party/authority in the destination country to confirm their requirements. Even within a country, different institutions may have different requirements or preferences. If they advise further authentication is required then the Notary can advise you on that or you can check the NZ Department of Internal Affairs website (Use your NZ documents overseas | New Zealand Government) which provides a country-by-country list that tells you whether a country requires an apostille or authentication?.

Key Differences between Apostille and Authentication?

Apostille:

  • Used for countries that are members of the Hague Apostille Convention.
  • It’s a single-step certification issued by the New Zealand Department of Internal Affairs.
  • The apostille certificate confirms that the signature, stamp, or seal on the document is genuine.
  • No further legalisation is needed by foreign embassies or consulates.

Authentication:

  • It’s sometimes also called legalisation.
  • Required for countries not part of the Hague Convention.
  • This process ensures that the document is recognized by countries with stricter verification requirements.
  • There are two types of Authentication:
    • Category A: Verified by New Zealand’s Authentication Unit, then checked by the Ministry of Foreign Affairs and Trade (MFAT); or
    • Category B: More complex. After NZ authentication, documents must go to the destination country’s embassy, which takes more time and costs more. If your document is for a Category B country, contact their embassy for instructions, payment details, and return options.

Harris Tate has been providing trusted, high-quality legal services to my family for over 30 years. Most recently, Danielle and Davina handled the conveyancing for both my property sale and purchase, and they were absolutely outstanding. Throughout what became somewhat of a challenging and unpredictable process, they left no stone unturned and managed everything with professionalism, care, and attention to detail. I genuinely could not have asked for more from them. Thank you to Grant Harris and the exceptional team at Harris Tate for consistently delivering first-class legal advice and service to our family, it is always very much appreciated!

My sister and I have used Harris Tate's services for a number of years. Recently we reviewed and renegotiated some contracts/agreements. Michelle Igasan and her capable team were professional, prompt, and showed great attention to detail. Michelle picked up things we had missed, and she had our backs throughout the whole process. We highly recommend Harris Tate.
