St Kevin's College (also called Redcastle) in Oamaru, New Zealand, is a Catholic, coeducational, integrated, boarding and day, secondary school.

Preference of enrolment is given to students who have established a link with the Catholic Church through baptism or membership of a parish.

Students participate in many sports including: hockey, rugby, basketball, soccer, netball, swimming, rowing, cricket, tennis, squash, badminton, skiing, snowboarding, multi-sport, athletics, tramping and kayaking.

There is an annual game with Waitaki Boys' High School (located near Redcastle) for the Leo O’Malley Memorial Trophy ("the peanut").

As at 2014, Waitaki was the more frequent winner hoisting the trophy on 53 occasions to St Kevin's 21 wins with 5 draws.

[15] In 2019, a million-dollar upgrade of the five-building hostel block was commenced with the aim of attracting more boarding student enrolments.

The Bishop of Dunedin, James Whyte, asked the Christian Brothers to set up the school.

He (with his brothers) made his fortune in developing and exploiting High Country sheep stations (particularly "Morven Hills" in the Lindis Pass) and by selling them at the right time.

[21][22] Redcastle was known for its beauty and its sporting associations (particularly those of St John McLean Buckley – He was, apart from his horse racing interests, president of cycling, coursing, gymnastic and tennis clubs[20]).

[23] In May 1926, Brother Moore, who had experience in fund-raising, came to Dunedin to organise a bazaar and lottery to fund the purchase of the land and the establishment of the college.

[16] The college was named after the Irish saint, Kevin (498–618), the founder of the monastery and school of Glendalough.

There were many priests and more than 2,500 friends and well-wishers present coming from Dunedin and nearby parts of both Otago and Canterbury.

[24] The Rector of Waitaki Boys' High School, Frank Milner, was present at the opening.

[25] For its first 56 years, St Kevin's College was typical of Christian Brother boarding institutions in Australia and New Zealand.

Individual Brothers taught throughout the day, coached sports teams after school, supervised meals and study, and were responsible for the dormitories at night.

Many of the pupils of these schools were the sisters, brother's or other relatives of St Kevin's College boys.

St Kevin's College thus became the "Heritage school" for Catholic secondary education in North Otago.

"In essence, our histories merged, the Dominican and Christian Brothers' values united, and educational opportunities were enhanced for students.

[28] St Thomas's Girls' Secondary School was established in 1935 and was accommodated in the Rosary Convent and adjacent buildings.

The Chapel of the Sacred Heart was opened in 1920[31] and this was used by St Thomas's during all the time that the school existed.

"[33] Another Dominican school for girls had closed in 1977 but it's memory is also part of the tradition of St Kevin's College.

St Patrick's College, a secondary boarding school for girls operated by the Dominican Sisters, existed at Teschemakers, 10 kilometres south of Oamaru, for 65 years from 1912 to 1977.

The school was associated with the McCarthy family of North Otago which donated the property, and it opened with seven Dominican sisters and seven boarders.

The college's fine buildings were erected and the beautiful and tranquil surroundings impacted on and shaped the lives of the pupils and teachers.

[34][30] The Gothic revival chapel of the Holy Rosary was commissioned in 1912 and paid for by the generosity of a local benefactor from Oamaru, Frances Grant.

[35][36] Teschemakers, once home to 140 boarding girls, was closed as a school, mainly because there weren’t enough sisters to teach and manage it.

After the sale, there was controversy over the future of the Gothic Revival-style Carrara marble altar with its alabaster depiction of The Last Supper.

[31] [32] Numbers of pupils had declined considerably and the Dominican sisters could not provide staff for such a small group.

In sport, 2 Silver Ferns and 7 All Blacks (including 3 captains) have been students at St Kevin's.
