Health Minister Simeon Brown has commissioned a review by the Ministry of Health into the response to the cyber security breach involving patient information on ManageMyHealth.
Health New Zealand has apologised to a woman who spent 11-and-a-half hours at Wellington Hospital's emergency department, but was never seen by a doctor.
Thousands of patients caught up in the ManageMyHealth ransomware attack could be at risk of identity theft or extortion, cyber security experts are warning.
