Two minor reshuffles were made during the Shadow Cabinet's duration, to reflect the decisions of two MPs not to seek re-election at the general election scheduled for September 2020.

[5] Collins, a former Minister of Justice and two-time aspirant to the party leadership who did not contest the May 2020 vacancy, was appointed Shadow Attorney-General and Spokesperson for Economic Development.

Selwyn MP Amy Adams, who, like Collins is also a former Justice Minister and 2018 leadership contender, rescinded her previously-announced decision to retire at the 2020 general election and was ranked third with the new position of Spokesperson for COVID-19 Recovery.

It was also reported that Muller had intended not to assign portfolios or a rank to Bridges' former deputy Paula Bennett,[9] who had unsuccessfully attempted to retain this position under the new leader.

[11] Ultimately, Bennett was placed thirteenth and lost her social investment portfolio to Louise Upston and role as the party's election campaign chair to Brownlee.

[12] Anne Tolley, who had previously indicated her intention to be the party's nominee for Speaker but was demoted fifteen places in the Muller Shadow Cabinet, also announced her retirement.

[13] The six National Members of Parliament that had previously indicated they will not contest the general election (David Carter, Nicky Wagner, Nathan Guy, Maggie Barry, Sarah Dowie and Alastair Scott) were not ranked or assigned a portfolio.

Former leader Simon Bridges was returned to the Shadow Cabinet in Reti's former position of 17, and took over from Gerry Brownlee the Foreign Affairs portfolio that he had previously requested.
