If offshore your copies must be certified
Most of your documents must be certified if you’re offshore. In the tool above we tell you when the documents can be just copies and when they must be certified copies. Certified means the document has been stamped and signed by a person to be a true copy of the original. The certifier must be approved to take statutory declarations in your home country or in New Zealand – for example a:
- lawyer
- Notary Public
- Justice of the Peace
- court official.
