To use your New Zealand documents overseas, document authentication may be necessary.

When you need to use a New Zealand document in another country, you might be asked to get the document apostilled or authenticated (some countries call this legalisation). An apostille or authentication is an official government certificate that proves the signature, stamp or seal on a document is genuine.

In New Zealand, this process is managed by the Department of Internal Affairs.  For information on what to do to get your documents authenticated, please visit the New Zealand Government website (external link)
