Katrina Casey, MoE head of sector enablement and support, says a commissioner is always appointed when a board resigns so that governance of the school is maintained until the school is ready to elect a new board of trustees.
The school first requested governance support in February this year, via the New Zealand Schools Trustees Association (NZSTA).
"When difficulties arise in the governance and leadership relationship in a school, the first support is usually provided by NZSTA," Ms Casey said.
"If the issues cannot be resolved, the ministry may use a statutory intervention to manage the issues."
The ministry would only intervene if there were risks to the operation of the school, to student achievement or to student welfare and safety.
Boards of trustees were responsible for all employment matters in schools, Ms Casey said. But former chairwoman Leanne Cordeaux said the board had resigned because trustees felt powerless to implement changes in management style and were unable to support staff.
Ms Cordeaux said the mass resignation had forced the ministry to take seriously the board's concerns that "our hands are tied behind our back.
"We have the role of supporting staff but we can't do that. We cannot override the school principal in decision-making. We could not do our job."
Ms Cordeaux said the breakdown in the relationship between the school and surrounding community had been sorely felt. Some children whose parents had moved them from the school were fourth-generation pupils.
