He entered politics at an unexpectedly young age, following the death of his father Harry Iauko, MP for Tanna and Minister for Infrastructure, Public Utilities and Public Service in Prime Minister Sato Kilman's government, on 10 December 2012.
His father, despite having been a highly controversial figure, convicted in 2011 for aiding and abetting intentional assault (having supervised the beating up of a journalist who had criticised him), had remained popular on Tanna, where there remained a strong tradition of handing on leadership positions to family members of deceased leaders.
[2] Pascal Iauko, at the age of just 27, was elected in a landslide victory, with the largest vote tally in the country's history.
[2] In October 2013, the Iauko Group, under the leadership of Tony Nari, merged back into the Vanua'aku Pati, and joined Prime Minister Carcasses' parliamentary majority.
[3] On 22 October 2015, he was found guilty of bribery, was sentenced to three years in prison, and lost his seat in Parliament.
