The Definition of “Personal Information”

"Personal information" as used in the NDL rules shall mean information related to a living individual which falls under any of each following item:

  • (i)those containing a name, date of birth, or other descriptions etc. (meaning any and all matters (excluding an individual identification code) stated, recorded or otherwise expressed using voice, movement or other methods in a document, drawing or electromagnetic record (meaning a record kept in an electromagnetic form (meaning an electronic, magnetic or other forms that cannot be recognized through the human senses) ) )whereby a specific individual can be identified (including those which can be collated with other information and thereby identify a specific individual)
