A new website

CERT NZ launched Own Your Online, a new website designed to help individuals and small-to-medium organisations understand cyber security and strengthen their cyber resilience. From its launch in late October to the end of the year, the website had close to 48,000 visits.

Cyber Smart Week and EXPOSED

The seventh annual Cyber Smart Week took place between 30 October and 5 November 2023. We had 1,214 organisations sign up as supporters, a whopping 136% jump from 514 in 2022. We also worked with seven key industry partners to help share the message with their extensive customer base.

The week started with EXPOSED, a free public exhibition of photographs featuring 10 people who were affected by online incidents. Three of these stories are now a part of our ongoing Own Your Online campaign that encourages New Zealanders to be more secure online.
