St Peter's School was also prominent in St Patrick's Day celebrations. On Friday 17 March 1865, St Peter's boys together with pupils of other Catholic schools began their celebrations with a Pontifical High Mass whose principal celebrant was Bishop Pompallier, in the cathedral. After addresses to the Bishop, the pupils went to the "paddocks" of Peter Grace Esq where "the sports for the youths consisted of feats of bat and ball, football etc. etc. A very spirited cricket match came off between 11 students of St Francis de Sales School [(a girls' school)] and a corresponding number of St Peter's School, the former being the victors in the game". In 1867 the celebration occurred on Monday 18 March. After Mass, the addresses to the bishop were read by a pupil of St Patrick's School and by "Master Anthony Martin, son of Mr Anthony Martin of Hobson St" on behalf of St Peter's. The pupils then went to paddocks of Mr Dinnin on Ponsonby Road for sports, entertainments and "refreshments".
