On 2012, August 3, the ITU updated its Table of International Call Sign Series to reflect a call sign change for Niue Island. The island will now have the entire E6 prefix block. Niue, an island approximately 1700 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. Niue, which is about 1.5 times the size of Washington, DC, has a population of almost 600 people.
