I am now offering sealed translations from English into Spanish thanks to this handsome new stamp I received from the New Zealand Society of Translators and Interpreters:
New Zealand government agencies, for example, demand certified translations of all documents you turn in, which ensures it is not realised by an untrained person, computer translation software, or a friend or family member who is not a professional linguist. These translations should bear the stamp and signature of the translator, which in this case looks like that pretty stamp above, provided by NZSTI.
**Update: I am now offering official translations into both English and Spanish. New seal and all!
