Nixon Duban

At the 2017 election, Duban lost his seat to Bryan Kramer, who had lodged the court petition that had unseated him back in 2013.

In October 2014, after a prolonged court-ordered recount of the 2013 by-election results, Duban was affirmed as having been duly re-elected. In November 2014, election petitioner Bryan Kramer was arrested on charges of conspiring to kill Duban, though these were dismissed in June 2015. In January 2016, Duban was shifted to the position of Minister for Transport and Infrastructure, but was moved back to Minister for Petroleum and Energy that July.

Duban was elected to the National Parliament on his second attempt at the 2012 election, and was promoted to Minister for Police in O'Neill's post-election Cabinet reshuffle. As minister, he launched the Police Modernisation Concept, which saw K200 million additional funding to improve police vehicles, infrastructure and other logistics. On 3 June 2013, the National Court declared his 2012 victory null and void after finding that he had engaged in bribery and undue influence during the campaign, ordering a by-election in his seat. The Police Association responded by thanking Duban for his "foresight and vision" as minister and stating that their membership were "very grateful".

Duban won the by-election in December 2013, returned to parliament, and was reinstated as Minister for Police a month later. Several of his opponents had criticised the government for promising Duban a guaranteed position in Cabinet if he were to be returned, and having Prime Minister O'Neill retain Duban's former police portfolio in an acting capacity until after the by-election. In February 2014, he was promoted to Minister for Petroleum and Energy after the dumping of William Duma. He signed the development license for the Stanley gas condensate project in May. In June 2014, he suggested that Papua New Guinea should pass legislation to regulate social media in the country because "opportunists and social media freaks are abusing these freedoms and rights".
