The number of people dropping out of a rheumatic fever treatment programme raises further concerns about the Government's high-profile goal of stamping out the disease, the Green Party says.
The Government made cutting rheumatic fever rates by two-thirds one of its top 10 priorities for the public sector in 2012, but failed to reach its target by the deadline last month.
In the Budget, it halved funding for the programme, as the Ministry of Health decided to focus on the most at-risk population groups rather than every district health board.
Counties Manukau DHB has one of highest rate of rheumatic fever cases. New figures released under the Official Information Act show that 58 of the 628 patients added to a rheumatic fever register in Counties Manukau in the past two years had fallen off their treatment plan.
The DHB said the main reason for disengaging with their treatment was transience. Patients' contact details were not known or they had left the region.
