In 1994 he moved to the current affairs programme "20/20", and later presented an interview/current events segment of "3 News" (now "Newshub"). After John Hawkesby left "3 News" in 1998, Campbell was asked to fill in, and he remained as the main "3 News" weekday newsreader along with Carol Hirschfeld until 2005. He began "Campbell Live" with Hirschfeld in March 2005. On 21 May 2015, TV3 announced that "Campbell Live" would soon cease to air, and Campbell had decided to leave MediaWorks, despite having been offered a position co-hosting a replacement current affairs programme. Only one year of the offered three-year extension was to have been presenting Campbell Live, and the network was insisting the programme become more entertainment-driven and reduce its concentration on core Campbell Live subjects, such as Christchurch after the earthquakes, child poverty, Pike River, and so on. The final programme aired on 29 May 2015.
