Patients at Middlemore Hospital have faced long delays today after a major computer system crash, affecting test results and communications.
Counties Manukau District Health Board spokeswoman Lauren Young said the failure had been traced to two recently installed firewalls that had brought the computer system throughout the hospital to a halt.
Ms Young said the issue was "bureaucratic" and staff were mitigating the affect on patients.
"It's a bureaucratic issue, it's not affecting patient care," she said.
"Of course it's irritating for clinicians and irritating for patients who are having to wait for paperwork."
