St Joseph's School in Levin, which boasts current All Black Cody Taylor and former Olympic swimmer Dean Kent as former students, is due to celebrate its centenary.
A group of former students and staff have begun working towards a two-day centenary celebration, to be held in Levin on February 1 and 2, 2020.
Organiser Stasia Kennedy said the centennial will provide an opportunity to not only share personal stories from the past, but to also connect with the school community today.
"The Sisters may be gone, but our community will continue as kaitiaki of their service to St Joseph's past, present and future students," she said.
The school was founded in 1920 by the Sisters of St Joseph of Nazareth, often referred to as "the Black Joes" because of the black habit that they wore.
