Background

Research run #4 · 26 Apr 2026
Every claim below traces to a verbatim quote in the cited source. Click any footnote [1] in the prose, or expand the citation index below, to see where the fact came from.

Hon Casey Costello is a New Zealand First Member of Parliament, having entered Parliament in 2023 as a list MP [23][33].

Costello began her career as a police officer, with one source placing her entry into the police in 1986 [3]. She went on to serve as a Detective Sergeant [1], and according to a single reputable secondary source, also held the role of Vice-President of the New Zealand Police Association [31]. A further single source indicates she served as vice-president of the police union more broadly [16].

Following her policing career, Costello held managerial roles in the security and construction industries [10]. According to a single reputable secondary source, she served as manager of security and operations at Parliament during the 2000s [9], and also worked as general manager of a building services company [8]. She is additionally noted, according to single reputable secondary sources, as a business owner who advocated for victims of migrant exploitation [6], and as a trustee of the Migrant Exploitation Relief Foundation [15].

Prior to joining New Zealand First, a single reputable secondary source indicates Costello was a board member of the New Conservatives Party from 2019 [14].

Costello entered Parliament as a New Zealand First list MP following the 14 October 2023 general election [24][32]. Sources differ on the precise start dates of her ministerial appointments, though multiple sources confirm she has held the offices of Minister of Customs [28], Minister for Seniors [27], Associate Minister of Health [17], Associate Minister of Immigration [18], and Associate Minister of Police [19], all from 2023. One source notes her Associate Minister of Health role carried specific responsibility for tobacco policy [25]. She has also been described, according to a single reputable secondary source, as a Cabinet Minister in the 54th New Zealand Parliament from 2023 [20].

Looked for, not found

  • No public record found of Casey Costello's secondary school education (Marcellin College, Auckland mentioned on Wikipedia but quote not verifiable in source body). Cannot corroborate from a second source.
  • No specific dates found for Casey Costello's tenure as Vice-President of the New Zealand Police Association.
  • No public record found confirming Casey Costello's exact year of birth (sources say 1965 or 1966).

The agent checked these topics across the allowed public sources but could not find verbatim-quotable evidence. Absence doesn't rule the fact out — it just means no journalist-accessible source covered it at run time.
