Shadow Cabinet of Simon Bridges

Portfolio allocations were amended six times throughout Bridges' tenure as leader to accommodate the departures or planned retirements of members. The first change was made two weeks after the formation of the Shadow Cabinet, on 26 March, with the resignation of Jonathan Coleman. Coleman had been the spokesperson for health and sport and recreation, portfolios he had held ministerial warrants for in the previous government. Michael Woodhouse, a former hospital chief executive, gained health. Education spokesperson Nikki Kaye picked up sport and recreation. Woodhouse's portfolio of workplace relations and safety was added to the responsibilities of environment spokesperson Scott Simpson.[8]

In October 2018, a series of events that involved the leaking of Bridges' travel expenses saw transport and infrastructure spokesperson Jami-Lee Ross stand down from his portfolios while undertaking personal leave (ostensibly for "deeply personal" health issues, although Ross would later claim that this was a false statement put out by Bridges and Bennett) before resigning from the National Party. Judith Collins and Paul Goldsmith picked up Ross's portfolios.[9] The third resignation, in January 2019, was of former Attorney-General Chris Finlayson.[10][11] His shadow Attorney General portfolio went to Amy Adams and a new drug reform portfolio, responding to the Government's decision to hold a referendum on legalising the sale, use, possession and production of cannabis in 2020, was assigned to Paula Bennett.

In June 2019, Adams and Wairarapa MP Alastair Scott announced they would not seek re-election to Parliament at the 2020 general election. Along with the retirement of list MP and Māori development spokesperson Nuk Korako in mid-May, this triggered a broad reshuffle.[12] Paul Goldsmith received Adams' finance portfolio and became the third-ranked MP. Goldsmith's economic and regional development portfolios were split between Todd McClay and Chris Bishop, who was promoted to the second bench and also gained the transport portfolio. Jo Hayes was promoted to be spokesperson for Māori development and Treaty of Waitangi negotiations, but retained a low ranking. Tim Macindoe became Shadow Attorney-General and Gerry Brownlee returned as foreign affairs spokesperson.

Agriculture spokesperson Nathan Guy announced his intention to retire at the next election in July 2019. He was replaced by Bridges' eventual successor to the leadership, Todd Muller, whose climate change portfolio was passed to Simpson.[13] The sixth and final reshuffle, in February 2020, featured minor redistributions of portfolios following announcements that Maggie Barry (on 5 November 2019), Nicky Wagner, Sarah Dowie and David Carter (all on 11 February 2020, although Carter had previously indicated his intentions on 17 October 2018[14]) would retire at the next election.[15]
