Saint Johns is an Auckland suburb. The suburb was named after St Johns Anglican Theological College, a religious training college established in what became the suburb in 1844 by Bishop Selwyn. The College of St John the Evangelist is the theological college of the Anglican Church in Aotearoa, New Zealand and Polynesia. The complex of buildings occupies the crest of the hill and once commanded expansive views of the harbour to the north. The earliest buildings from the 1840s are the work of the Frederick Thatcher, Bishop Selwyn's primary architect. Thatcher is largely responsible for what is now referred to as the "Selwyn Style"; wooden gothic buildings based on Saxon examples, primarily Greensted Church, in the small village of Greensted-juxta-Ongar in Essex. These structures tend to have pronounced exposed wood beams on the exterior, gabled 60-degree-pitch roofs and lancet windows.
To the south of Remuera Road lies Waiatarua Park. This is a natural basin, prone to seasonal flooding. On several 19th century maps this was shown as a lake and referred to as 'Lake Remuera', 'Lake St John' or 'Lake Waiatarua' although in reality it was largely an area of swampy ground in which a sheet of shallow water would appear sporadically in the wet season. In 1918 133 acres of this land was given to the City Council to create Waiatarua Park. As the surrounding farm land was transformed into suburban housing this area became problematic - although in theory the "lake" afforded a picturesque view for the new houses but as it wasn't constantly present it couldn't really be used as selling feature like Lake Pupuke on the North Shore. Conversely it was a breeding ground for mosquitoes and a source of smells as the basin was composed of a peat-like substance subject to smouldering fires which were difficult to put out. In 1929 a drain was bored through the hill to the south west enabling the water to be drained into the adjacent natural stream which feeds into the nearby Orakei Basin; this drainage system is still in place.
In 1934 Fifty acres of the park were leased to the Remuera Golf Club and a course was laid out. The clubhouse was completed in 1935. In 1938 a new course was built around the original layout in response to members’ complaints about the course conditions. In 1968 the Course was redesigned by golf course specialist Harold Babbage and a new Club House built. Much of the suburb was developed in the 1960s and 70s when at that time it was seen as a popular place for families to live. The area is part of the catchment for Selwyn College, the local state secondary school.
