On August 3, the ITU updated its Table of International Call Sign Series to reflect a call sign change for Niue. The island will now have the entire E6 prefix block. Niue -- an island approximately 1500 miles northeast of New Zealand -- is a self-governing island nation that has been in free association with New Zealand since 1974. Prior to the change, the island used ZK2. According to the CIA World Factbook, Niue is about 1.5 times the size of Washington, DC, and has a population of almost 1300 people.  -- Thanks to The Daily DX for some information
