The New Brunswick Liberal Association held a leadership convention on August 6, 2022, in Fredericton, New Brunswick, as a result of Kevin Vickers' announcement on September 14, 2020, that he was resigning as party leader. Vickers resignation followed the outcome of the 2020 New Brunswick general election which saw the Progressive Conservative party, under Blaine Higgs, form a majority government and the Liberal Party lose three seats. The deadline for candidates to file their intention to run for the leadership was June 15, 2022. Voting by party members for the leadership occurred at a free in-person convention as well as remotely via phone and internet connected device and used a ranked ballot system.
Susan Holt was elected leader on the third ballot.

Withdrew or failed to qualify.
Seamus Byrne.
Seamus Byrne is a Saint John businessperson. After being the frontrunner for most of the campaign, Byrne failed to meet the May 2 deadline to pay the $30,000 entrance fee and submit the required 50 signatures of Liberal members willing to support him and was disqualified from the race. Byrne fought the ruling, claiming that the requirements were anti-democratic, and the Greenlighting Appeal Committee agreed with Byrne's position, and therefore, on May 17 granted his campaign a two-day extension to submit the entrance fee and signatures. The main issue was that Byrne had initially paid the $30,000 entrance personally and he did not have the time to source the funds from third parties during the two-day extension period. As a result, Byrne suspended his campaign on May 20. Early in the campaign, Byrne published a 15-point policy plan for New Brunswick. This plan has now been adopted by the Liberal Party of New Brunswick and will form the policy basis of the next Liberal governments in New Brunswick. Byrne expressed his intention to continue in politics in New Brunswick in the future.
