Funding to reduce rheumatic fever in New Zealand has been halved in this week's Budget.
That is despite the Government's failure to reach a target of reducing hospitalisations for the serious illness, which is one of its top 10 priorities for the public sector.
The Budget shows funding for rheumatic fever has fallen from $10 million a year to $5 million a year.
The disease is often caused by living in cold, damp homes and disproportionately affects young Maori and Pacific people.
The Ministry of Health began its prevention programme in 2011, and expanded it in 2012 after the Government made it one of its Better Public Service targets.
The Government set a goal of reducing the rheumatic fever rate from 4 cases per 100,000 people to 1.4 cases per 100,000 people by mid-2017.
The rate hit a low of 2.4 cases per 100,000 people in mid-2015, but has since risen again to 3.4 cases per 100,000 people.
