Hon Dr AYESHA VERRALL (Associate Minister of Health): Madam Speaker, as a worker in a district health board, I've been trusted with the personal information of thousands of New Zealanders—information on their illness, their family situation, the investigations that they've had. Some of that information is particularly sensitive. I was an infectious diseases doctor, and some of the information we collect in our histories of patients tell details of their sex life, of their drug use, many things people wouldn't want shared publicly. Sometimes, it is that particularly sensitive information that harms people when their privacy is breached, but sometimes it's not even that—it's the very fact that you were in hospital that you do not want to have known. The information we have, when we provide care to people, is extensive now, because of the large amount of information that can be stored and collected in modern information systems—it is still personal, and patients rightfully expect for it to be protected when they come to hospitals.
