[3] Immediately prior to entering politics, Hudson had a career in information technology, working in business development, contracting, sales and account management for major international firms such as IBM, Oracle, and Telstra-Clear – as well as New Zealand-owned consultancy StarFish.

Hudson retained the Police and Government Digital Services portfolios through the leaderships of Bridges' successors Todd Muller and Judith Collins.

[7][8] During his time in Parliament, Hudson marked himself out as a social liberal on conscience issues, by voting in favour of legislation that: decriminalised abortion; set up a referendum to enable euthanasia; and allowed territorial authorities to decide whether to permit Easter opening in their respective districts.

He voted against cannabis liberalisation in January 2018 (in line with caucus colleagues), and supported the introduction of an Australian-inspired, 'Strike Force Raptor'-style, anti-gang squad while he was Police Spokesperson in 2019.

[11] Hudson also serves as Chair of the Audit and Risk Committee on the board of Able Minds, a mental health charity that seeks to support those suffering from distress and addicition, and their families and whānau.
