It could be at least three days before Lakes District Health Board's computer system, containing crucial patient information, is restored, after a fire at Rotorua Hospital.
The Rotorua Fire Brigade was called to the fire at 12.50am today , which was contained in the hospital's Uninterruptible Power Supplies (UPS) system.
Eight elective surgeries planned for tomorrow and some out-patient clinics have been cancelled. Those patients affected have been contacted.
"There are different patient management systems we cannot access which contain important patient information. For reasons of clinical safety, we've had to postpone appointments because we can't access all the patient information," said Lakes DHB communications officer Sue Wilkie.
"Patients with a scheduled appointment who haven't been contacted should come in for their planned appointment."
