Andrew Michael 'Mike' Bush is a retired New Zealand police officer who served as the 29th Police Commissioner of New Zealand from April 2018 to April 2023. Born in 1963 in New Zealand, Bush joined the New Zealand Police in 1980 at age 17, beginning a 43-year career. He progressed through various roles including frontline policing, criminal investigation, and leadership positions such as District Commander in Wellington and Assistant Commissioner. Bush was appointed Commissioner in 2018 following the resignation of Mike O'Reilly. His tenure was marked by overseeing responses to major national crises including the 2019 Christchurch mosque shootings, the COVID-19 pandemic enforcement, and various natural disasters. He emphasized community engagement, cultural reform within the police, and addressing institutional racism, particularly following the independent review into police conduct after the mosque attacks. Bush implemented initiatives to modernize the police, such as increasing diversity in recruitment and enhancing mental health support for officers. He received honors including the New Zealand Order of Merit (QNZM) in 2013 and Officer of the New Zealand Order of Merit (ONZM) earlier in his career for services to policing. Bush retired in 2023, succeeded by Andrew Coster, and has since taken on advisory roles including consulting on security matters. His career is noted for a focus on restorative justice and building trust between police and Māori communities, reflecting his commitment to biculturalism in New Zealand society. Post-retirement, Bush has been involved in public speaking and governance positions, such as on the board of the Department of Corrections.
