A report on the collapse of Southern District Health Board's computer system says it was caused by a staff member mis-typing a code.
The IT system broke down in February for more than 34 hours, leaving Dunedin Hospital unable to access electronic records.
The report to the Southern DHB said most of its computers shut down because the system ran out of storage.
It said IT staff were unaware of the storage problems, as computer-generated alerts did not get through because of a mistake in typing a 12-digit electronic address.
