The banks' compliance divisions have a very close relationship with the Privacy Commissioner's office. Many times, when they have a question about compliance, they will talk to that office.
As an association, we host an annual meeting with the regulator so that we have the opportunity to exchange information with them. But the banks on a regular basis, as a breach may happen—in the rare instances when one does happen—are certainly in touch with the Privacy Commissioner's office so that they are aware of what is happening and are able to monitor what is going on and give advice as to how we can handle it.
We participated in the development of the Privacy Commissioner's guidance on breach reporting and notification. The banks certainly follow that guidance.
