About 40 patients have become ill with a stomach bug at Auckland clinics and hospitals.
Patients at North Shore Hospital, the forensic psychiatric unit the Mason Clinic and the Taharoto Mental Health Unit have fallen ill.
The illness is thought to be a 24-hour bug and is not linked to the listeria infection reported in Hawkes Bay last week.
Staff were alerted to the bug on Sunday evening when several patients became ill with vomiting and diarrhoea.
An investigation is underway and staff are working closely with other agencies, including Auckland Regional Public Health Service, to identify the cause of the illness, chief medical officer Andrew Brant said.
Brant said infection control measures were being used where appropriate.
Patients discharged from any of the named facilities over the past couple of days who are experiencing vomiting and diarrhoea are advised to see their GP if symptoms persist.
