Mrs McKeen said the hospital had been getting the message out through churches, radio and other local media on how to manage respiratory illnesses and to "go early to your own doctor".
The latest weekly reports from influenza surveillance programmes, up to last Sunday, estimate the number of people going to GPs with flu-like illness at 40 per 100,000 patients, averaged across most areas nationally. But it was 83 in the Auckland and Counties Manukau health districts, and more than 100 in Waitemata.
A spokeswoman for the Waitemata District Health Board, which runs the North Shore and Waitakere hospitals, said they were busy, but not so busy as last week, when a number of elective surgeries had to be postponed.
"We still want to encourage people to go to their GPs in non-emergency situations," she said.
An Auckland City Hospital spokesperson said it had had a busy week. Occupancy yesterday was 86 to 88 per cent.
