During 2016, with the announcement that the Head of College planned to retire in 2017, the Trust Board rigorously reviewed the structure of Saint Kentigern as one organisation. The position of Head of College was disestablished and from the beginning of 2017, the former positions of Heads of Senior and Middle Schools at the College were renamed, Principal Middle College and Principal Senior College, with their roles moving towards a full responsibility principalship. Mr Duncan McQueen (Middle College) and Mrs Suzanne Winthrop (Senior College) were appointed to these roles.
After an extensive review period during 2019, the Trust Board made the decision to return the College to a single College model, disestablishing the roles of Middle College Principal and Senior College Principal. The Board was pleased to appoint Mr Russell Brooke as the new College Principal. Coming from the Principal’s role at ACG Parnell, Mr Brooke took up his tenure in March 2020. He, along with the Principals of the Boys’ and Girls’ Schools, Mr Peter Cassie and Ms Juliet Small, reported to the new Head of Saint Kentigern, Mr David Hodge who took up the role at the start of Term 2, 2017.
In 2021 Mr Brooke left Saint Kentigern and after a short and devastating illness Mr Hodge passed away in 2021. The Trust Board again reviewed the structure and in 2022 appointed Dr Kevin Morris as Executive Trustee responsible for overall leadership of the Saint Kentigern organisation.
