Tasmania's elective surgery waiting times have risen again and are now more than four times the national average, a new report says.
The Productivity Commission report shows that in 2011-12, 11.5 per cent of Tasmanian patients waited more than 12 months for their procedure.
The figure has risen from 9.4 per cent the previous period.
"Elective surgery patients who wait longer are likely to suffer discomfort and inconvenience," the report says.
The State Opposition's health spokesman Jeremy Rockliff says the report is proof the State Government's cuts to the health system are hurting sick Tasmanians.
"When you have a situation where you cut elective surgery as savagely and as quickly as Michelle O'Byrne, the Minister, the Labor Minister has done then these are the dire consequences that result," he said.
"Our plan is to invest $76 million back into elective surgery and that funding will increase and re-open hospital beds, 40 hospital beds statewide and re-employ 110 frontline health staff."
Nationally, only 2.7 per cent of patients had to wait more than a year.
The report also identified a rise in the number of serious medical errors in Australia.
