Hon ANDREW LITTLE (Minister of Health): Madam Chair, thank you, and I thank the member for raising that question. That is a very big question that not just public health entities deal with but private as well. I think the single biggest compromise of health data we had was actually a private health provider. It was a primary health organisation where the health records of a million patients were potentially compromised through an encroachment by a bad actor. Upon investigation, it was found more likely than not that information wasn't exfiltrated, but certainly the person who compromised the system had the opportunity to do so over a considerable period of time. And then you've got the situations like the Waikato District Health Board, where a ransomware attack happens and data is exfiltrated and is placed on the dark web. So those are real things that have happened. That really highlights the need for high-quality IT systems, and that's why we've invested nearly half a billion dollars in upgrading and renewing health IT systems, but also the need for high-quality data security and cyber security.
