Police said in the past 12 months, High Alert social media pages have reached 1.1 million people, with the audience being predominantly aged between 18 and 34 and living in urban centres. Detective Inspector Blair Macdonald, police manager in the National Drug Intelligence Bureau (NDIB), said a key objective for DIANZ was to build a mailing list, so it can reach people via email when issuing an alert. More than 211,000 people have visited the High Alert website over the past year, generating more than 329,000 page views.
