Sources for New Zealand
Every source used for the New Zealand pages, what each supports, how it was accessed, and where its scope ends.
Facts on this page were checked against their sources on .
The New Zealand pages rest on the Constitution Act 1986 and the Policing Act 2008 (both fetched from mirrors because the official legislation site is behind a WAF), the judiciary's own site and the Ministry of Justice for the courts, the Crown Law Office for prosecution, the Independent Police Conduct Authority for oversight, the Supreme Court's judgment in Ellis v R for tikanga, and the World Prison Brief for the prison figures. Each was read or retrieved and confirmed on 27 July 2026 and independently re-checked; sections 23/24 of the Constitution Act, section 16 of the Policing Act, and the World Prison Brief figures were re-confirmed by hand.
The full register, with the precise scope and stated limitations of every source, is published in the repository at docs/research/new-zealand-source-register.md.

Constitution Act 1986 (New Zealand)
Parliament of New Zealand (via the UN FAO FAOLEX mirror) · Legislation · 1986-12-13 · link verified 2026-07-27
The Constitution Act 1986 (Public Act 1986 No 114), fetched as a PDF from the UN FAO FAOLEX mirror (the official legislation.govt.nz is behind an AWS WAF JavaScript challenge) and text-extracted; ss 23 and 24 re-confirmed verbatim in two passes. Supports that New Zealand has no single supreme-law constitution — the Act organises the State into Part 1 (the Sovereign), Part 2 (the Executive), Part 3 (the Legislature) and Part 4 (the Judiciary) — and s 23 (a High Court judge may be removed only by the Sovereign or Governor-General on an address of the House of Representatives, on the ground of misbehaviour or incapacity) and s 24 (a judge's salary may not be reduced during their commission). Establishes judicial independence and the uncodified, parliamentary-sovereignty framework.
Courts of New Zealand — the judiciary and the courts
Courts of New Zealand (Te Kōti o Aotearoa) · Government publication · link verified 2026-07-27
The judiciary's own site, read directly. Supports that "the Constitution Act 1986 recognises the three branches of government — the legislature (Parliament), the executive … and the judiciary", that "each operates independently of the others … known as 'the separation of powers'", and that the security of tenure and salary in ss 23 and 24 are described as "ancient guarantees"; and the ordinary court hierarchy (Supreme Court → Court of Appeal → High Court → District Court, plus specialist courts including the Māori Land Court).
Ministry of Justice (New Zealand) — the court system: the Supreme Court
Ministry of Justice (New Zealand) · Government publication · link verified 2026-07-27
The Ministry of Justice's court-system pages, read directly. Supports that the Supreme Court of New Zealand (Te Kōti Mana Nui) is "New Zealand's final court of appeal", with "the role of maintaining overall coherence in the legal system", and that it "replaced the Judicial Committee of the Privy Council in London as New Zealand's final court of appeal on 1 July 2004".
Crown Law Office (Te Tari Ture o te Karauna) — about us
Crown Law Office (New Zealand) · Government publication · link verified 2026-07-27
The Crown Law Office's own site, read directly. Supports that the Attorney-General (a Minister, the senior Law Officer) and the Solicitor-General (the junior Law Officer and chief executive of Crown Law) superintend the prosecution process, that Crown Law's Public Prosecutions Unit oversees Crown and non-Crown prosecutions, and that serious ("Crown") prosecutions are conducted by Crown Solicitors — private-practice lawyers holding the Crown warrant in each main centre. Establishes that New Zealand has a Law-Officer prosecution model rather than a standalone Director of Public Prosecutions. (The verbatim "apolitical"/prosecutor-independence wording appears in the Solicitor-General's Prosecution Guidelines, not on this page.)
Policing Act 2008 (New Zealand), s 16
Parliament of New Zealand (via a police-human-rights-resources mirror) · Legislation · 2008 · link verified 2026-07-27
The Policing Act 2008 (Public Act 2008 No 72), fetched as a PDF mirror and text-extracted; s 16 re-confirmed verbatim. Supports s 16(1) (the Commissioner of Police is responsible to the Minister for carrying out the functions of the Police, its general conduct and management, and giving effect to lawful ministerial directions) and s 16(2) (the Commissioner "must act independently of" any Minister regarding the maintenance of order, the enforcement of the law, "the investigation and prosecution of offences", and decisions about individual employees). Establishes a single national police force and its operational independence from ministers on investigations.
Independent Police Conduct Authority (New Zealand) — about us
Independent Police Conduct Authority (New Zealand) · Government publication · link verified 2026-07-27
The IPCA's own site, read directly. Supports that the Independent Police Conduct Authority is "an independent body set up by Parliament to keep watch over the Police", that "we are not part of the NZ Police" and "under law we are fully independent", that it was established in 1989, and that it receives and investigates complaints against the Police. Establishes the external police-complaints body.
Ellis v R [2022] NZSC 114 (Supreme Court of New Zealand)
Supreme Court of New Zealand (Te Kōti Mana Nui) · Court record · 2022-10-07 · link verified 2026-07-27
The Supreme Court's judgment in Ellis v R [2022] NZSC 114 (7 October 2022). Cited, by attribution, for the majority's acceptance that tikanga (Māori law/custom) "was the first law of Aotearoa New Zealand" and may be engaged as part of the common law, with the Court noting it does not have the mandate or expertise to "declare" tikanga as it declares the common law. Used to record, accurately and by attribution, that tikanga Māori is a recognised source of law — not as a decorative aside.
World Prison Brief — New Zealand
Institute for Crime & Justice Policy Research (ICPR), Birkbeck, University of London · Academic · link verified 2026-07-27
The World Prison Brief country page for New Zealand (compiled by ICPR from national sources), read directly and re-confirmed by hand. Supports: prison administration by the Department of Corrections; a total prison population of 11,255 including pre-trial detainees at 31 March 2026 (source: Ministry of Justice); a rate of 211 per 100,000 based on an estimated national population of 5.34 million; and an official operational capacity of 10,633 dated 30 June 2019. The capacity figure is seven years older than the population figure, so no current occupancy level is taken from the page. Cited only for these figures and the administering department.
