The Privacy Commissioner thinks individuals affected by the Waikato District Health Board data hack should be notified

The DHB's still in crisis mode, as it continues to wrestle with the cyber attack that hit last week.

The group claiming to be behind it, is threatening to leak the information publicly.

John Edwards says he received information that reveals the hackers do have sensitive patient data.

He says in the scramble to get the systems back up and running, it must be remembered there are people involved.
