Minimum Cyber Security Standard: How to achieve and maintain compliance
In an era of rapidly evolving cyber threats, New Zealand has taken a decisive step forward in strengthening its digital security posture by implementing the Minimum Cyber Security Standard. The National Cyber Security Centre (NCSC) has introduced comprehensive Minimum Cyber Security Standard that represent a fundamental shift in how government agencies approach cybersecurity. These standards, set to take effect April 2026, establish clear expectations for foundational cyber security practices across New Zealand’s public sector.
The Ten Requirements
NCSC Minimum Cyber Security Standard
The framework comprises ten critical standards that cover the fundamental aspects of organizational cybersecurity. Learn more about them below.
| 1. Security Awareness* | Ensuring staff receive relevant, up-to-date security training that aligns with the organization’s risk posture and reflects changes in business, technology, and the threat landscape. |
| 2. Risk Management* | Implementing a defined, documented risk-based approach to identify and control cyber security risks as part of broader organizational risk management. |
| 3. Assets and Their Importance* | Establishing frameworks and processes for asset identification, classification, and management throughout their lifecycle. |
| 4. Secure Configuration of Software* | Adopting secure-by-design approaches and industry best practices rather than relying on default software configurations. |
| 5. Patching | Implementing systematic processes to identify, evaluate, and deploy security patches across systems and applications. |
| 6. Multi-factor Authentication | Deploying MFA to protect business-critical and external-facing systems from unauthorized access and compromise. |
| 7. Detect Unusual Behaviour* | Establishing processes to identify and respond to abnormal activity within organizational environments. |
| 8. Least Privilege* | Incorporating the principle of least privilege when designing and authorizing system access. |
| 9. Data Recovery | Implementing robust data recovery capabilities to protect against data loss risks. |
| 10. Response Planning* | Developing and testing cyber-incident management plans to ensure business continuity during security events. |

The Capability Maturity Model Approach
The standards include a capability maturity model outlining steps for uplift and areas requiring attention. The minimum level has been set at CMM2 Planned & Tracked. This structured approach provides organizations with a clear pathway for improvement across five maturity levels:
- CMM 1 (Informal): Ad-hoc, unmanaged security capabilities
- CMM 2 (Planned & Tracked): Well-formed security practices with repeatable processes – This is the minimum requirement
- CMM 3 (Standardised): Integrated, standardized security capabilities across the enterprise
- CMM 4 (Quantitatively Controlled): Measured, monitored security performance with strategic focus
- CMM 5 (Optimising): World-leading practices with near real-time response mechanisms
Scope and Application
The Minimum Cyber Security Standards apply to all business-critical and external facing systems. The standards are mandatory for GCISO-mandated agencies, which include core government departments and agencies handling sensitive information or providing critical services.
The NCSC is coordinating closely with the Protective Security Requirements (PSR) team and has aligned its consultation and publication timeframes
However, the NCSC encourages non-mandated agencies and even private sector organizations to adopt these standards to enhance their overall cyber resilience. This broader adoption would contribute to strengthening New Zealand’s collective cyber security posture.
June – July 2025
Public consultation period with GCISO-mandated agencies and industry partners
October 2025
Final standards publication and implementation deadline
April 2026
First compliance reporting as part of the Protective Security Requirements (PSR) assurance process
By the above dates, all mandated agencies must meet the baseline requirements and be ready to demonstrate compliance.
Why These Standards Matter
The introduction of these standards addresses several critical needs:
Addressing Growing Threats
Earlier this year, the NCSC revealed that the country faced increasingly sophisticated cybersecurity threats from criminal entities and foreign state actors. In its inaugural year as New Zealand’s primary operational cybersecurity agency, the GCSB reported a total of 7,122 cybersecurity incidents for the period ending June 30, 2024.
Establishing Clear Expectations
The standards provide unambiguous guidance on what constitutes adequate cybersecurity, moving away from open-to-interpretation frameworks toward specific, measurable requirements.
Enabling Systematic Improvement
The maturity model approach allows organizations to understand their current position and plan systematic improvements over time.
Reducing Compliance Burden
By integrating with existing PSR processes, the standards minimize additional administrative overhead while maximizing security outcomes.
Practical Implementation Considerations
Organizations should consider several factors when implementing these standards:
Asset Classification
Begin with a comprehensive inventory and classification of business-critical and external-facing systems to understand the implementation scope.
Gap Analysis
Conduct thorough assessments against each standard to identify current maturity levels and prioritize improvement areas.
Resource Planning
Allocate appropriate budget, personnel, and time for implementation, recognizing that achieving CMM2 may require significant organizational change.
Integration Approach
Align implementation with existing security initiatives and business processes to maximize efficiency and minimize disruption.
Continuous Improvement
Establish mechanisms for ongoing assessment and improvement beyond the minimum CMM2 requirement.
