About 280,000 New Zealanders are waiting for elective surgery, and more than half are not on waiting lists, new research shows.
The report by TNS for the Health Funds Association (HFA) and the Private Surgical Hospitals Association (NZPSHA) showed those who were on waiting lists had been waiting an average of 224 days.
HFA chief executive Roger Styles said more public and private surgery was being done over the past decade, but the ageing population meant the need was growing.
"The 280,000 waiting on both the official waiting list and the 'hidden' list are virtually all public patients because of public rationing," Mr Styles said.
"There is no real private waiting list, as private patients are seen promptly. The private and public outcomes are hugely different because of this."
