Our Lady Star of the Sea, Burnside Primary and Ohoka schools all needed letters of support in 2019 and 2018.
Also included in the report was that three Canterbury schools could not reasonably estimate their cyclical maintenance provisions.
The schools are Hagley Community College, Oxford Area School, and Russley School.
"These schools were uncertain about whether they would need to maintain their buildings in the near future due to significant future building works.
The uncertainties for some of these schools arise because they are part of the Christchurch Schools Rebuild Programme," it said in the report.
Based on the financial information collected by the Ministry by mid-October, schools across the country received $499 million of locally raised funds in 2019.
Five hundred and eleven
schools received $153 million in revenue from international students. Of those schools, the revenue for 46 schools was equivalent to more than 20 per cent of their expenditure (excluding teachers' salaries and notional rents that are funded
directly by the Ministry), with the highest being 49 per cent.
