Under the name Paul Foster, Foster-Bell contested at the
2002 general election, losing to
Labour Party incumbent
David Benson-Pope. He was ranked 56 on the National Party list, too low to be elected as a list MP. In the
2011 general election he stood in the
Wellington Central electorate and lost to Labour incumbent
Grant Robertson. Foster-Bell was not initially elected as a list MP, but was called to Parliament in May 2013 to replace
Jackie Blue who retired. He was sworn in on 28 May 2013 and gave his maiden statement, quoting
Margaret Thatcher,
Jenny Shipley and
Winston Churchill, on 12 June. In his first term, he was a member of the health committee and the justice and electoral committee; at the end of the term he became the latter's deputy chair. Foster-Bell sought the National Party nomination in the electorate for the
2014 general election, but was beaten by new candidate
Shane Reti. Instead, he stood again in Wellington Central, losing again to Robertson and being returned as a list MP. In his second term, he was deputy chair of the education and science committee, later of the government administration committee, and also sat on the local government and environment committee. In 2016 Foster-Bell announced that he was gay in response to remarks made by
Destiny Church leader
Brian Tamaki regarding homosexuals. A
member's bill in Foster-Bell's name passed unanimously in April 2016, exempting
Royal New Zealand Returned and Services' Association (RSA) veterans' clubs from limitations in the
Sale and Supply of Alcohol Act 2012 so they could lawfully serve traditional tots of liquor at gunfire breakfasts on
Anzac Day. A second bill, the Arbitration Amendment Bill, was selected for introduction in March 2017 and completed its first reading that May. This bill aimed to change New Zealand's
arbitration regime to "conform more closely to international standards" drawn in the member's bill ballot. It eventually passed its third reading under the stewardship of
Andrew Bayly in May 2019. Foster-Bell courted controversy in 2016 which eventually led to his retirement from politics. In June, news broke that he had 12 staff leave his office in the 2013–2016 period, amidst claims by former staffers that he had bullied them. Foster-Bell strongly denied these allegations, saying that he was not a bully. Later that month his travel expenses, totalling more than $61,000 for a one-year period. He was defended by prime minister
John Key who said that Foster-Bell's expenses had incurred from travels around the country presenting on foreign affairs and occasionally filling in for ministers. A former Key staffer and
Fonterra executive,
Nicola Willis, challenged Foster-Bell for the National Party's nomination in Wellington Central. Foster-Bell withdrew from candidate selection in February 2017, enabling Willis to win the nomination unopposed and announcing his retirement from politics at the
2017 general election. He made his final speech in the House on 16 August 2017. ==Later career==
