Saint Kentigern College is a private, co-educational Presbyterian secondary school in the Pakuranga suburb of Manukau City in the Auckland region of New Zealand, beside the estuary of the Tamaki Estuary. It is operated by the Saint Kentigern Trust Board which also operates Saint Kentigern School in Remuera and Saint Kentigern School for Girls (former Corran School). Established in 1953, the college is semi-coeducational with a single-sex middle school for years 7 and 8, with years 9 and 10 single sex in core subjects and a co-educational senior school for years 11-13. Kentigern (or Mungo) is the patron Saint of Glasgow. In 2003, the college introduced girls into the school for the first time with 140 female students. There are now over 540 female students attending, with numbers increasing every year. Saint Kentigern College is an IB World School offering the IB Diploma Programme for Year 12 and 13 students. The Saint Kentigern Trust Board approved the decision in late 2006. The course was first offered to Year 12 students in 2009. Saint Kentigern College opened in 1953 on an rural site 16 kilometres from the centre of Auckland, bordering the waters of the Tamaki Estuary.
