New Zealand identifies China as its most persistent state-backed cyber threat.

The agency's annual Cyber Threat Report described China as the most persistent and capable state actor conducting cyber activity in New Zealand. It also linked suspected activity to actors from Russia, Iran and North Korea.

The report said 86 of 369 incidents considered potentially nationally significant in the year to June 2026 had suspected state-sponsored links. China has routinely denied Western allegations of cyber espionage.
