Ardouin commenced as a radio presenter with Volcano Radio 88.5FM Lyttelton in December 2008 with his first programme, "Heading Home with Kenny". The show was an afternoon programme known for playing mainstream pop music, and ran for approximately 18 months before Ardouin moved to host a new breakfast show "Seismic Shift". Ardouin commenced this programme in September 2010 following the 2010 Canterbury earthquake and was named to reflect the programme's diversity of music and Ardouin's bluntness on current affairs. Although starting out as light-hearted, the "Seismic Shift" became more poignant following 22 February 2011 Christchurch earthquake which had a devastating effect on the radio station's host town of Lyttelton. Ardouin's programme became more focussed on earthquake recovery at this time, including regular interviews with members of the Earthquake Commission, Christchurch City Council and Prime Minister John Key. Ardouin's programme continued until the city was hit by the June 2011 Christchurch earthquake which caused the closure of Volcano Radio. Ardouin retired from broadcasting at this time, however announced in July 2015 that he will be returning to radio to present a current affairs and investigative journalism programme "Wireless Watchdog" on Christchurch and Canterbury's Plains FM. The live programme debuted on 6 August 2015 and aired weekly in 2015 on Thursdays at 9pm and Fridays at 11am. Since early 2016, the programme was broadcast fortnightly on alternate Thursdays and Fridays. He is known for promoting equity and equality and challenging those who deny others of this.
