Vanguard Military School has become the first charter school to get approval to become a "designated character" state school.
Minister of Education Chris Hipkins says the Albany-based school will reopen as a state school next year, and is likely to expand to become a full secondary school covering all Years 9 to 13.
"Vanguard Military School was the first of 11 charter schools currently operating to put in an application to become part of the state system under section 156 of the Education Act 1989, and now it's the first to be approved," he said.
"The school will use the ethos and training methodology of the military across the curriculum and in the day-to-day running of the school, to achieve attitudinal and academic excellence. This will form part of its designated character. It will also continue to have a special focus on 'second chance' students."
Hipkins said the application was assessed by the Ministry of Education, and consultation with the boards of schools in the Auckland network whose rolls might be affected had taken place.
