What we’ve done


Eight advisories issued to individuals, businesses and IT specialists.

Advisories are our early warning system for New Zealanders. They are an important way to get actionable advice out to New Zealanders about the threats they need to respond to, so they can protect themselves against attacks.


116,000 website visits, up 5.26% on Jan – Jun 2019, and 18% on July – Dec 2019.

12 new content pages published, offering practical advice ranging from safe remote working for employers and employees, to secure online transacting for businesses.

Pacific and international engagement

CERT NZ’s active membership of the international cyber security network helps us understand the threat landscape, respond to incidents and build cyber resilience within New Zealand and regionally.

We do this by participating in forums such as the PaCSON and APCERT working groups.

Domestic engagement

New initiative: Webinars

Five national webinars were conducted with chambers of commerce, professional bodies and membership organisations, attracting more than 850 participants.

“The cyber security webinar delivered to our business community by CERT NZ is one of those ‘must attend’ workshops.”
