GCSB Annual Report 2025

Our Mission

Intelligence advantage and cyber resilience to successfully navigate an unpredictable world. 

We support protecting New Zealand as a free, open, and democratic society by contributing to: 

• the protection of New Zealand’s national security 
• the international relations and well-being of New Zealand, and 
• the economic well-being of New Zealand. 

We achieve this through:  

Intelligence collection and analysis

• Using our Signals Intelligence collection capabilities to produce 
  intelligence that provides decision advantage to government agencies in 
  conduct of their functions.  

Detecting, disrupting and deterring high impact cyber threats

• The NCSC detects, disrupts and deters high impact cyber threats and 
  provides cyber security services to individuals, businesses and 
  organisations, government, and operators of critical infrastructure.  

Our contributions to national security are formed around six outcomes

Of our six outcomes, three focus on our work to protect New Zealand, and three focus on ensuring that we are a strong and resilient agency:

• Protect – Tiaki Tangata: We protect New Zealand; our people, infrastructure and information.
• Build resilience – Tiaki Oranga: We build resilience in others so that New Zealand can confidently navigate future security challenges.
• Catalyse – Tiaki Hononga: Our products and services are based on customer partnerships and enable real-world outcomes that advance New Zealand’s values and interests.
• Resilient: We invest in the GCSB’s resilience so that we can better serve New Zealand.
• Trusted: We are a trusted and confident organisation. We make positive impact, and the value we bring to New Zealand is well understood.  
• Future focused: We will ensure we have the right relationships, coordination, and tradecraft to respond to and counter both existing and emerging threats.  

By pursuing our Strategy, we will achieve the following key shifts: 

• Deep insights on regional security – for New Zealand and for the Pacific. We will prioritise our work on regional security to ensure the New Zealand Government has deeper insight and forewarning on the array of security challenges facing the Pacific. We will develop our role in building regional resilience by providing support to government agencies whose responsibilities include responding to security issues in our region.  
• Consolidate national cyber security leadership. We will establish the GCSB’s role as the lead agency for cyber security operations in New Zealand. We will consolidate reporting pathways and response triage for cyber security incidents.
• Embed our responsibilities as a Treaty Partner to advance cyber resilience with iwi, hapū and Māori organisations. We will work with partners to define and give effect to our role in lifting the cyber resilience of iwi, hapū and Māori organisations.
• Lift New Zealand’s ability to keep pace with emerging technology risks and opportunities. We will employ a more structured approach, which combines insight from all of the GCSB’s functions and capabilities, to assist the Government to keep pace with the risks and opportunities that emerging technologies present to New Zealand.
• Catalyse our customers’ use of intelligence. We will work in a way that means our customers benefit from the full range of what we have to offer. We will join the dots for our customers, including on how they can use our products, advice and services.
• Position ourselves to be future focussed to effectively meet security challenges and increased demand. We have a focus on continuing to make the GCSB a great place to work, prioritising recruitment and our physical work environment. We will modernise our workplace, enhancing how we connect and collaborate with our customers, partners and suppliers and build adaptability to short-term shocks and longer-term changes in our operational environment.
