Authenticating official documents for use overseas
An authentication or apostille certification tells a foreign government or authority that a New Zealand document is official.
If you need to use a New Zealand-issued document (like your birth certificate) overseas, foreign officials may ask you to get an 'apostille', 'authentication' or 'legalisation' certificate. These are standard certificates issued by the government that prove your document is authentic.
Different countries have different rules about what you need — check the list below to see what you need to do.
If English isn't an official language in that country, you may also need to get your document translated. You can organise this at the same time as your apostille or authentication.
