Medbury School, located in Christchurch, New Zealand, is an independent day and boarding preparatory school for boys between Years 1 to 8 (ages 5 to 13).

[2] Medbury School was established in 1923 by the Chennells family after purchasing a property of 20,000 square metres (220,000 sq ft) and a large family home called "Ripsford".

By 1925 the number of boys attending the school had grown to approximately 50.

In 1955 the Chennells retired; by this time there were 111 boys at the school.

[4][5] Boys are accepted into Medbury School at any level between the ages of five and thirteen at the discretion of the Headmaster.
