This quarter, CERT NZ received 870 incident reports. This is the highest number of reports to date. The reports show that a broad cross section of New Zealanders and organisations are impacted by cyber security issues. They also show a significant increase in both incident type and financial impact compared to Q2.
Some examples include:
- financial losses increased by 35% to $2.9 million
- reports related to scam and fraud were almost double what we saw in Q2. This was due to a large number of webcam scam reports
- reports of unauthorised access increased by 28%
- although we received reports across all age groups, the 65+ age group experienced the highest value of direct financial loss. The total loss for this age group was $930,000 this quarter, compared to $123,000 in Q2.

Unauthorised access reports
Reports of unauthorised access continue to increase. We received 91 reports this quarter, a 28% increase on quarter two.
More than a third of these reports related to attackers being able to access business and personal email accounts through weak account passwords.
Case study: Business compromise leads to advisory
An IT provider noticed that one of its clients was receiving emails pretending to be a recognised supplier.
The emails contained fake invoices and were attempting to trick the client into paying the invoiced amount into the attacker’s account.
