"Today's investment will provide around 460 extra student places, adding to the 680 additional places announced in June," she said.
"In total, we plan to deliver 4000 extra student places for the Auckland region as part of Budget 2017.
"Auckland is one of our fastest growing areas, and the Government is committed to ensuring the city's school network can accommodate this.
"This year's Budget provided an additional $8 million to support the ministry to better forecast and plan for future growth in the school network."
Macindoe said the replacement classrooms were included with the new builds for economy of cost and to allow flexible learning spaces to be built.
The new classrooms would have high-quality lighting, acoustics and ventilation as well as the latest digital infrastructure, he said.
Macindoe said as well as new classrooms, the $240 million investment would deliver four new schools, one major school expansion, the relocation of two special education schools to co-locate on one site and additional special education satellite units.
