Federal Labor has called for a rewrite of the controversial My Health Record legislation to prevent insurers and employers from exploiting patient data and to protect domestic violence survivors.

The opposition is drafting a suite of amendments to address weaknesses with the digital health records system raised in last month's Senate hearings, where medical experts and unions raised serious concerns that the current legislation could allow patient data to be used for commercial purposes.

"The Australian people need guarantees that the My Health Record won’t be privatised or commercialised," opposition health spokeswoman Catherine King told Fairfax Media.

"And they need guarantees that private health insurers will never get access to their data."
