Privacy Commissioner Angelene Falk has also raised concerns with Mr Hunt and the Australian Digital Health Agency, which is administering the scheme, while former AMA President Kerryn Phelps highlighted concerns with the legislation and warned that GPs may boycott the system.
The Australian Digital Health Agency admits there has been nine data breaches.
"My Health Record will provide health practitioners with significantly enhanced access to the information they need to treat their patients safely and effectively".
The policy changes were welcomed by the AMA with Dr Tony Bartone tweeting, "Government will strengthen privacy provisions under the #MyHealthRecord Act, removing any doubt".
The Australian Digital Health Agency, the system operator of My Health Record, had previously said its policy was not to release patient records to police and government without a court order.

Queensland Health Minister Dr Steven Miles has threatened to disrupt the three-month opt-out roll-out period, calling for this week's Council of Australian Governments (COAG) meeting on Thursday between states and territories to discuss whether to suspend it. "This will be enshrined in legislation", Hunt said.
The Australian government has agreed to overhaul its controversial My Health Record system amid concerns about privacy protections.
That aspect of the e-health system was so contentious that when the Parliamentary Library published an opinion that the legislation did, in fact, provide warrantless access to the records, the piece was briefly unpublished before being replaced with a version that was less confronting to the government.
And - Vulture South is certain you'll be thrilled to hear this - the release also trumpets that the government will work with medical leaders on some kind of spin strategy, or as the release puts it, "additional communications to the public about the benefits and goal of the My Health Record".
"Privacy of health records is vital, and it is good that the Minister has responded to these concerns and provided the necessary assurances", Mr Tambassis said.
"My Health Record always promised compelling health benefits, especially for people living in rural and remote areas".More news: Asia shares subdued for central bank, data test
Doctor groups also welcomed the changes.
People who did not have access to a computer to opt out online could ring the My Health Record opt out hotline, he said.
"Changes to the legislation that remove any questions about who may be able to access the records ensure that the records will be able to be used in line with the RACGP's position statement on My Health Records".
"I also welcome the additional communications to the public to assist individuals make an informed decision as to whether or not to have a My Health Record".
The Minister also said that the legislation would be amended to ensure that if a person wishes to cancel their My Health Record, they will be able to do so permanently, with that record deleted from the system.More news: Audacious Russell powers Windies to series lead
