NZ Government’s Cyber Rules Are Clear – Is Your Incident Response Ready?
The New Zealand Government has stepped up its expectations. With the release of new cyber guidance on Minimum Cyber Security Standards, Risk Management, and the INFOSEC Policy from the Protective Security Requirements (PSR), the message is clear: security maturity is no longer optional, and reactive incident response won’t cut it.
This isn’t just advisory material to file away; it’s a clear signal of the baseline organisations are now expected to meet. Agencies, Crown entities, and businesses working with or alongside government need to sit up. The days of ‘we’ll deal with it when it happens’ are over.
Minimum Standards Mean Just That – Minimum
The new baseline requires enforceable configurations, hardened perimeter controls, and system-level visibility. If your Security Operations Centre (SOC) can’t detect unusual behaviour fast, or worse, if logs aren’t even retained, you’re already out of compliance. These aren’t aspirational goals; they’re mandatory expectations. Incident response must plug directly into these controls, or else it will fail when it matters most.
Risk Isn’t a Buzzword – It’s the Operating Model
The updated risk management guidance pushes organisations to prioritise based on actual threat exposure and business impact. Incident response needs to reflect that. No more cookie-cutter playbooks. If your crown jewel systems or citizen data repositories aren’t mapped and prioritised in your response strategy, you’re flying blind.
The INFOSEC Policy Lays Down the Governance Line
This is where accountability becomes critical. If information isn’t appropriately classified and protected, or if business owners are not clearly engaged in the response process, the organisation may fall short of the expectations outlined in the Protective Security Requirements. In the event of a cyber incident, any gaps in preparation or unclear roles can quickly escalate into a governance issue—placing significant pressure on senior leadership to explain why response capabilities didn’t meet the required standard.
What Should Organisations Actually Be Doing?
- Get Honest About Detection Gaps: Stop assuming your monitoring works and test it. Validate alerting, response times, and access visibility across your most critical systems.
- Rewrite Your Playbooks Around Risk: Generic plans won’t help when you’re dealing with real-world ransomware or insider threats. Build scenarios based on your threat model, not someone else’s.
- Stress Test with the Right People in the Room: Your response plan is only as strong as the people executing it. Include execs, legal, comms, and system owners in exercises. If they can’t make the right calls under pressure, fix it.
- Enforce Role Clarity Across the Business: If nobody knows who leads during an incident, or what data is most important, response time doubles and consequences multiply.
- Treat Compliance as Evidence, not a Paper Exercise: Be ready to demonstrate how your plans, capabilities, and governance align with government expectations. This is now part of the trust equation, especially in public sector and regulated environments.
The Bottom Line
The NZ Government has drawn a line. These updated standards and policies are the floor not the ceiling. If your incident response capability can’t confidently detect, prioritise, and coordinate a whole-of-business response to cyber threats, you’re behind. And in today’s threat landscape, behind quickly becomes breached. Contact us if you need to discuss how to make the necessary improvements to your incident response processes.
