[10] The People's Alliance Party of New Brunswick was created in the spring of 2010 amidst opposition to the provincial government's plan to sell NB Power to Hydro-Québec, and was officially registered on June 9, 2010.

Kris Austin, a former interdenominational minister and candidate for the Progressive Conservative Party nomination in the Grand Lake-Gagetown riding, was leader from 2010 to 2022.

In the end, only CTV (Bell Media) kept Austin and Coon out of its roundtable debate, which was aired three days before election night.

The party had two third-place finishes with LeRoy Armstrong in Sussex-Fundy-St.Martins and deputy leader Wes Gullison in Southwest Miramichi-Bay du Vin.

[20][21] At a December 18, 2018 committee meeting, MLAs of the province increased the budget of the Auditor General by $1 million, something that had long been in the platform of the People's Alliance.

The Commissioner of Official Languages also received a 25 percent budget increase, even though the People's Alliance campaigned on abolishing the office.

[22] The raise was met with criticism by the Liberal opposition, as cuts were subsequently made to infrastructure projects in sectors including healthcare and education.

Kris Austin and Michelle Conroy announced their departures from the People's Alliance of New Brunswick to join the Progressive Conservatives on March 30, 2022.
