Thousands of patients promised elective surgery are waiting longer than the Government-ordered maximum of six months - which next year will shrink to five, then four months.
Waikato District Health Board was the worst performer nationally in the latest Health Ministry statistics, which are for January. In the Auckland region, the Auckland DHB had the greatest number waiting too long, particularly patients needing eye surgery.
At the other end of the national scale, Counties Manukau, an acknowledged leader in elective surgery, had the lowest proportion of patients waiting too long, only 0.2 per cent.
Yet although more than 1000 Auckland and Waikato patients - including 302 being treated by the Waitemata DHB - waited too long, these boards met the Government's more widely publicised target of increasing the number of operations performed.
Nationally about 106,000 patients a year had elective surgery from 2001 to 2005, but the number has risen each year since, to 145,400 in the year to last June. In the past five financial years, Counties Manukau has increased its amount of elective surgery by more than half - to 15,600 patients.
