A group of four health IT companies, including New Zealand's leading practice management system and secure messaging vendors, have asked the Office of the Privacy Commissioner to look into a new data extraction and storage system run by ProCare that contains identifiable medical data on up to 800,000 Auckland patients.

Representatives from HealthLink, Medtech Global, myPractice and Best Practice NZ have written to the Privacy Commissioner about the data collection, saying they are concerned that patients don’t appear to be aware their medical records are being copied into new databases.
