Senior production each year (in collaboration with Rangi Ruru Girls' School or St Margaret's College), an annual House Singing competition and the REACTION House Play festival, where each house forms a group of students to perform a play for the Tothill Cup Interhouse Drama Trophy. Students are encouraged to partake in areas they have not attempted before, especially within these inter-house arts competitions. Sport Sport is compulsory for all boys; there is an extensive selection of sports available with boys choosing both a summer and winter option each year. As well as school sports, there are ongoing inter-house sports competitions, where all students are expected to participate in, or to come and support their houses. Extra sporting activities are also available: for example, the school ski club buses to the ski fields on weekends during winter terms. Sports facilities on site include Upper, the school playing field, an all weather facility, a 5-lane indoor 25-metre heated swimming pool, gymnasium and weights room. Offsite facilities include the nearby Christ's College cricket ground (which also has football and rugby fields) which consists of four hectares of South Hagley Park, and Kerr's Reach on the Avon River which is home to the Christ's College rowing club, consisting of a boat house which houses top quality rowing equipment. It is claimed that a form of rugby was being played at the school as early as 1853. Each year its rugby team plays with Wanganui Collegiate School, Wellington College and Nelson College in a tournament known as the "Quadrangular". It also has a long-running rivalry with Christchurch Boys' High School, and an annual rugby match between the two schools is fiercely contested. House system In keeping with the tradition of English public schools, Christ's College has ten Houses accommodating around 700 students. There are three boarding houses and the dayboys are organised into seven more houses. Each house has a housemaster responsible for the care of the boys. From the school's early days, Houses were a base for boarders within the school, and these changed their names as Masters came and went. The name Jacobs has been retained, while others have been replaced by School, Richards and Flower's. It was not until 1909 that the first two day-boy Houses were established. They were named 'North Town' and 'South Town', and students were allocated to them depending on whether their homes were north or south of
