Doi was an unsuccessful candidate for the Northern Provincial seat at the 1997 election and 2002 election.[1] Following his 2002 defeat, he announced that he would no longer contest elections himself, stating that he would "leave it to a younger breed of leaders". He remained president of the People's Action Party, but resigned in July 2004 amid controversy over MP Jamie Maxtone-Graham's attempt to cross over to the party.[2][10]
In June 2005, he called for autonomy for Papua along the same lines as that granted to Bougainville.[11] In March 2006, he was appointed as a director of Port Moresby's water and sewerage provider, Eda Ranu.[12] He was subsequently appointed chairman of the company.[13]
