New Zealand Security Intelligence Service (NZSIS) is New Zealand’s civilian security-intelligence agency. It investigates threats to national security, advises ministers and other decision-makers, and provides protective-security advice and security-clearance assessments. Its work is distinct from the policing functions of the New Zealand Police and the signals-intelligence responsibilities of the Government Communications Security Bureau (GCSB).[1][4]
Established in November 1956 as the New Zealand Security Service, it was renamed in 1969. Its history includes Cold War counter-espionage, surveillance of political movements, and disputes about the limits of secret entry and information disclosure. The Intelligence and Security Act 2017 brought NZSIS, GCSB and their oversight arrangements under one statute, largely following the review by Michael Cullen and Patsy Reddy.[2][4]
Origins and Cold War operations
The immediate predecessor was the New Zealand Police Special Branch, established in 1949. Peter Clayworth’s account for Te Ara identifies criticism of Special Branch by New Zealand officials and visiting British and Australian security officers, concerns about police corruption, and the implications of Vladimir Petrov’s defection in Australia as factors behind the creation of a separate organisation in 1956.[2]
Herbert Ellery Gilbert, commonly known as Bill Gilbert, became the first director. Sidney Holland’s government wanted a New Zealander in charge, and John Marshall approached Gilbert, an army officer. Gilbert received instruction from Roger Hollis of the British MI5 and consulted the Australian Security Intelligence Organisation before beginning work in Wellington in 1957. The service followed the MI5 model rather than becoming a police force.[3]
Michael Cullen and Patsy Reddy’s review records that NZSIS initially watched organisations including the Communist Party of New Zealand and the Society for Closer Relations with Russia. Later it gathered intelligence on anti-war, anti-nuclear and Māori protest movements on the suspicion that they had been infiltrated by subversive elements.[5]
Espionage cases and political surveillance
In 1962 two Soviet diplomats were expelled after security investigations. In 1974 the economist and former senior civil servant William Sutch was arrested following surveillance by the NZSIS and charged with espionage. He was acquitted in 1975. Herbert Ellery Gilbert’s biography in the Dictionary of New Zealand Biography records that the service had recommended against prosecution, preferring to obtain Sutch’s cooperation.[2][3]
During the 1981 Springbok tour, NZSIS supplied Robert Muldoon with a list of eight people it called subversives and seven radicals not positively known to belong to subversive groups. Muldoon published the names to discredit the protest movement. Peter Clayworth also records the monitoring of organisations including Halt All Racist Tours, the New Zealand China Friendship Society and the Campaign against Foreign Control in New Zealand.[2]
Functions and legal powers
The Intelligence and Security Act 2017 gives the NZSIS and the GCSB shared intelligence and protective-security functions. They may collect and analyse intelligence in accordance with government priorities, advise specified recipients, and cooperate with the New Zealand Police and New Zealand Defence Force. Their objectives include national security, international relations and New Zealand’s economic well-being.[6][4]
The Inspector-General of Intelligence and Security explains that otherwise unlawful activities require authorisation. Type 1 warrants concern New Zealanders and require the responsible minister and a Commissioner of Intelligence Warrants; Type 2 warrants concern non-New Zealanders and are issued by the minister. Necessity, proportionality and the availability of less intrusive means are among the statutory considerations. The Inspector-General reviews warrants after issue.[6]
The Act also provides mechanisms for assumed identities, direct access to specified government databases, access to restricted information, and business-records directions to telecommunications operators and financial-service providers. Under section 19, exercising freedom of expression, including advocacy, protest or dissent, cannot by itself justify agency action. Operational functions must be performed independently and impartially, and directors-general have specific political-neutrality duties.[6][4]
International relationships
NZSIS participates in the wider relationships associated with the Five Eyes, but is not New Zealand’s signals-intelligence agency: that is the Government Communications Security Bureau. Bill Robinson distinguishes the original signals-intelligence partnership among GCSB, the National Security Agency, Government Communications Headquarters, Communications Security Establishment and Australian Signals Directorate from the broader security, intelligence and law-enforcement cooperation that developed around it.[7]
The 2016 review by Michael Cullen and Patsy Reddy described foreign partners as an important source of investigative leads and intelligence that New Zealand could not collect alone. It also considered the legal controls and accountability for international cooperation as part of the domestic intelligence framework.[8][9]
Oversight and controversies
The Choudry break-in
In 1996 David Small interrupted two NZSIS officers inside the Christchurch home of Aziz Choudry, an activist opposed to free-trade agreements. Choudry brought proceedings against the Attorney-General of New Zealand. The Court of Appeal found that the service’s entry was unlawful and amounted to trespass. The case became a focus of debate about the legal limits on security-intelligence operations.[2]
Disclosure of information about Phil Goff
In November 2014 the Inspector-General, Cheryl Gwyn, reported on information released by the NZSIS in July and August 2011 about briefings to the then opposition leader Phil Goff. She found that the service disclosed incomplete, inaccurate and misleading information to Cameron Slater and others, and failed to correct the resulting misimpression. Gwyn found no partisan political motive by the service or its director, and no political collusion or direction of NZSIS. She nevertheless found failures to take reasonable steps to safeguard neutrality and maintain an appropriate relationship with the opposition leader.[10]
Christchurch and counter-terrorism priorities
The Royal Commission of Inquiry into the Attack on Christchurch Mosques on 15 March 2019 found that the concentration of counter-terrorism resources on Islamist extremist terrorism before the NZSIS began its baselining project in 2018 was inappropriate. It was not based on an informed assessment of threats associated with other ideologies, nor a system-wide decision to maintain that allocation despite the absence of such an assessment.[11]
The commission also found that this inappropriate concentration did not cause the attacker’s planning and preparation to go undetected. It found no failure by agencies involved in counter-terrorism that was material to that non-detection, and no relevant failure in information sharing.[11]
Institutional oversight
The Inspector-General investigates legality and propriety, handles complaints, reviews authorisations and audits compliance systems. The parliamentary Intelligence and Security Committee examines policy, administration and expenditure, with statutory exclusions for operationally sensitive matters and matters within the Inspector-General’s jurisdiction. The Ombudsman, Privacy Commissioner, Controller and Auditor-General and courts also have oversight roles.[6][4]
