Core MPR Strengths
Defence Relationship with New Zealand
New Zealand retains constitutional defence responsibilities exercised through consultation. The Cook Islands conducts its own affairs and international relations within the free-association framework.
Functional Maritime Security Wing
The Cook Islands Police Maritime Unit conducts patrol operations, fisheries enforcement, and search-and-rescue missions across a vast Pacific EEZ with support from New Zealand, Australia, and regional partners.
Stable Internal Security Institutions
The Cook Islands Police Service provides law enforcement, border control, public order, civil protection, and emergency response with a professional domestic security role.
Strategic Location and Diplomatic Value
Located in the South Pacific, the Cook Islands plays a cooperative role in regional maritime security, illegal-fishing enforcement, disaster readiness, and Pacific stability.
MPR Doctrine and Strategy
The Cook Islands does not maintain a conventional military doctrine. Its security posture is civilian-based, partner-supported, and centered on internal policing, maritime enforcement, disaster response, and regional cooperation.
Defense and external military responsibilities are handled through the free association relationship with New Zealand, while the Cook Islands government retains internal autonomy and manages local security requirements.
The country's strategy emphasizes peaceful sovereignty, maritime law enforcement, climate and disaster resilience, and trust-based regional integration rather than independent armed defense.
Force Profile
The Cook Islands has no standing army, navy, air force, or reserve military structure. Its security personnel are organized under civilian policing and maritime-enforcement functions.
The domestic force is designed for public order, fisheries enforcement, border support, search and rescue, and disaster response rather than combat readiness or military deployment.
Ground Forces
The Cook Islands has no military ground forces. Internal security is managed through the Cook Islands Police Service and related civil agencies.
The country has no infantry units, armored forces, artillery, combat engineers, military logistics formations, or ground-combat doctrine.
Air Power
The Cook Islands has no air force or military aircraft. All airspace security and regional defense responsibilities are provided by New Zealand under the free association framework.
Rarotonga International Airport has emergency and dual-use relevance, but the country does not operate military aviation, airborne surveillance, strategic airlift, or air-defense systems.
Naval Forces
The Cook Islands does not maintain a navy, but its police maritime wing operates patrol vessels for EEZ enforcement, anti-poaching activity, search and rescue, and maritime sovereignty support.
The maritime wing's patrol vessels are supported by Australia, New Zealand, and regional maritime-security programs. Missions include exclusive economic zone protection, anti-poaching, search and rescue, and fisheries enforcement.
Missile Systems
The Cook Islands does not operate or possess missile systems. It has no ballistic missiles, cruise missiles, anti-ship missiles, surface-to-air missiles, tactical rockets, or missile-development infrastructure.
All strategic defense capabilities are externalized to New Zealand under the terms of free association.
Detailed Missile Inventory
| System Category | Status | Operational Role | MPR Assessment |
|---|---|---|---|
| Ballistic missiles | None | Not applicable | No strategic strike capability |
| Land-attack cruise missiles | None | Not applicable | No long-range precision-strike capability |
| Anti-ship missiles | None | Not applicable | No naval combat missile capability |
| Surface-to-air missiles | None | Not applicable | No independent air-defense capability |
| Tactical rockets and artillery missiles | None | Not applicable | No ground-combat fire-support capability |
Nuclear and Strategic Deterrence
The Cook Islands is non-nuclear and has no strategic weapons, military delivery systems, nuclear infrastructure, or strategic command architecture.
Its deterrence model is political and external, resting on the free association relationship with New Zealand and broader Pacific regional stability.
Cyber, Space, ISR, and Electronic Warfare
The Cook Islands has no military cyber command, military satellite inventory, electronic-warfare capability, or formal military intelligence service.
Maritime awareness and strategic intelligence are supported by New Zealand, Australia, and Pacific regional cooperation, especially for EEZ monitoring and illegal fishing enforcement.
Partnerships and Alliances
The Cook Islands relies entirely on New Zealand for defense under its free association relationship. It also receives maritime-security assistance from Australia and participates in Pacific Islands security dialogues.
New Zealand
New Zealand is responsible for the Cook Islands' defense and provides strategic backing, military coordination, disaster-response support, and external security protection.
Australia
Australia supports maritime enforcement, patrol-vessel capability, regional surveillance, and Pacific security cooperation relevant to the Cook Islands' vast maritime zone.
Pacific Islands Forum
The Cook Islands participates in regional security, climate, disaster-response, fisheries enforcement, and humanitarian coordination frameworks through the Pacific Islands Forum.
Consultation and executive authority
The April 2026 bilateral declaration affirms both New Zealand’s defence responsibilities and Cook Islands executive authority over its land, airspace, and exclusive economic zone. Free association rests on mutual consent; defence cooperation includes consultation rather than an automatic transfer of domestic sovereignty.
Combat History
The Cook Islands does not maintain a standing military, but Cook Islanders have served in overseas wars. Its modern police-led security system also draws on a long constitutional and practical relationship with New Zealand.
Cook Islanders in the First World War
Cook Islanders enlisted in the New Zealand Expeditionary Force during the First World War. Their service included the Māori contingents and the Rarotongan Company in the Sinai and Palestine campaigns. This individual and contingent service is distinct from maintaining a present national army.
Self-government and free association, 1965 onward
Self-government in free association began in 1965. New Zealand’s defence responsibilities operate through consultation, while the Cook Islands has its own government and international legal personality. The relationship supports external security without reducing the country to a territory administered by New Zealand.
Police maritime operations
The Police Maritime Unit conducts fisheries patrols, anti-smuggling work, search and rescue, and maritime surveillance. Australia handed over Te Kukupa II on 10 June 2022 as the Guardian-class successor to the original Te Kukupa. The successor vessel continues the police maritime patrol role.
Civil security and the 2026 declaration
Domestic agencies prepare for evacuations, infrastructure protection, and disaster relief, supported by training and practical cooperation with New Zealand, Australia, Fiji, and other Pacific partners. The declaration signed on 1 April 2026 reaffirms New Zealand as the primary defence and security partner and provides for consultation, access, information sharing, and greater practical engagement.
The Cook Islands’ MPR assessment remains one of small civil-security capacity and extensive partner dependence, with no conventional combat formations or ability to sustain an independent military campaign.
Geography, Economy, and Infrastructure
The Cook Islands is spread across the South Pacific, with volcanic islands such as Rarotonga and low-lying coral atolls. Its climate is tropical, moderated by trade winds, with a dry season from April to November and a wet season from December to March.
The country's dispersed geography creates maritime-security and disaster-response challenges, especially across its large exclusive economic zone.
Natural resources include fish, fruit, and offshore mineral deposits such as manganese nodules. The Cook Islands has no proven oil or natural-gas reserves and is fully dependent on imported fuels.

Why Cook Islands Ranks 201st
No Army, Navy, or Air Force
The Cook Islands has no military infrastructure, no trained combat personnel, and no plans to establish independent defense branches.
Zero Strategic Deterrence Capability
Without missiles, aircraft, heavy naval assets, air defenses, or combat forces, the Cook Islands cannot deter, repel, or project military force independently.
Complete External Dependence for Defense
An independent military response would exceed the Cook Islands’ resources. New Zealand is its primary defence partner, while Cook Islands authorities retain executive authority over their territory and take part in consultation and security decisions.
Small Force Size and Civilian Scope
The domestic police force is small and equipped for civil law enforcement, maritime surveillance, and disaster response, not military deployment or sustained defense operations.
The Cook Islands' ranking of 201st reflects its non-militarized governance, complete defense reliance on New Zealand, and internal focus on law enforcement, disaster resilience, and maritime surveillance.
While the country cannot engage in military operations or independent defense, its partnership with New Zealand supports sovereign integrity and regional integration.
