The state-integrated year 7 to 15 co-educational Catholic school has about 450 pupils.
Ministry of Education leader for the South Nancy Bell directed the appointment of a limited statutory manager (LSM) on April 5.
Timaru lawyer Nicola Hornsey has been appointed to the role but is on leave until next month.
In the meantime Dunedin school governance consultant Cleave Hay had been liaising with the board, but was not able to make a comment as Ms Hornsey was the LSM, he said.
"I’ve been assisting and doing some initial scoping interviews."
Ms Bell said while most schools operated successfully, a small number needed outside help to resolve concerns.
"In these situations, we are available to step in with the appropriate supports and expertise, allowing the school to focus on teaching and learning.
"The aim of any intervention is always to return the school to full self-management as soon as the recommendations of the intervention have been met."
The school’s board of trustees had sought support governing the school, she said.
Ms Hornsey had the functions, powers and duties as an employer to establish policies and procedures, to manage the curriculum, including teaching and assessment practice and to support the special character of the school, Ms Bell said.
"She will also advise the board on communication and financial operations."
Neither presiding board manager Ruth Mitchell nor principal Tara Quinney was willing to comment, referring the Otago Daily Times to Mr Hay.
