"The key stakeholders like teachers and parents really thought the programme increased access [for] children and their whanau."
The Mana Kidz clinics have been set up in 61 schools in the Counties Manukau DHB area to detect sore throats that can become rheumatic fever.
Other clinics have also been set up in other parts of the country under the Government's $65 million rheumatic fever prevention plan.
Dr Anderson said the research showed the Mana Kidz clinics provided broader healthcare than other clinics, and had improved other healthcare outcomes.
"If little Johnny has got a skin infection and his 2-year-old sibling at home has got a skin infection, the nurse working at that school can provide management for both."
Health Minister Jonathan Coleman said the Government's rheumatic fever awareness campaign had also been successful.
He said independent analysis by Allen + Clarke Policy and Regulatory Specialists had found the Government's recent $1 million campaign had been efficient, relevant and effective.
The Government aims to reduce rheumatic fever by two-thirds by next June.
