Goodfellow was a long-time National Party activist. On 2 August 2009, he succeeded Judy Kirk as Party President.^[3] In 2009, Goodfellow faced early opposition from within the party, with reports that events instigating the breakup of his marriage had soured his relationship with the party directors.^[4] However, he was re-elected by the party's Board of Directors in July 2010.^[5] Goodfellow's presidency coincided with National's term in Government under prime ministers John Key and Bill English, as well as the beginning of National's time in Opposition under leaders Simon Bridges, Todd Muller, Judith Collins and Christopher Luxon.

In early August 2021, Goodfellow survived a leadership challenge by former Speaker of the New Zealand House of Representatives turned National Party board member David Carter. In response, Carter announced his resignation from the National Party's nine-member leadership board.^[6][7] In June 2022, Goodfellow announced he would not seek re-election to the presidency in August 2022 but intended to remain on the board. On announcing his retirement, Goodfellow stated that he had intended to step aside from the role in 2016, but John Key's resignation as prime minister convinced him to remain in the role.^[8][9][10]
