New Zealanders need a local background check.

Overseas governments sometimes need proof that New Zealand documents are genuine before they will accept them. Please confirm requirements with the Embassy or Consulate of the country you are submitting the documents to. The Department of Foreign Affairs and Trade will certify that official signatures, stamps or seals on a document are genuine by checking them against a specimen held on file, and stamping the document with an Authentication or Apostille.
