An online charter school that opened just nine months ago already has permission to become one of the country’s biggest schools.

Aotearoa Infinite Academy opened at the start of this year with 200 students, and has approval to grow to 2000 next year and 3000 in 2028.

The secondary school’s growth is significant because other charter schools have remained relatively small, with the largest enrolling about 150 students.

A roll of 2000 would make the academy one of the 30 largest schools – and 3000 would put it in the top three to five, with government funding running to more than $20m a year.
