Some Christchurch schools are considering legal action against the Ministry of Education in a bid to stop their possible closure.
About 30 primary, intermediate and secondary schools - representing nearly 15% of the city's schools - could be closed or merged under a government proposal.
The schools have until December to report back to the ministry on why they think they should stay open.
Some want to challenge that consultation period.
Burnside Primary says it is considering taking the ministry to court to stop its possible closure.
Principal Matt Bateman says the school is already looking at what could possibly be challenged in court and how it could raise money to pay for its legal fees.
A meeting of affected schools is to be held next week to discuss collective legal action .
