In 1959, Archbishop Liston purchased on Mountain Road opposite the school. This land was owned by New Zealand Breweries and had been part of the Great Northern Brewery, later called Lion Brewery, which stretched from Khyber Pass along Mountain Rd up as far as Seccombes Rd. Part of the land purchased had been used as tennis courts for the staff. The land became available because, from 1950, New Zealand Breweries was concentrating its beer production at the Captain Cook Brewery further down Khyber Pass towards Newmarket. The Lion Brewery site was therefore sold off, part to the New Zealand Distillary Company and part, which included the tennis courts, to the Bishop of Auckland for St Peter's College. The site was purchased from New Zealand Breweries for £11,000 per acre, a concessional price. The sum was paid by the parents of the school through fairs, raffles and money contributions. Students were involved in picking up stones and glass from the field, sometimes as a detention. The site was used as a rugby field (at first called "the Far Field" or "the New Field" and now, "the Cage"). Located on it is a sports' pavilion called the Brother P. C. Ryan Sports Pavilion. It is named for Brother PC "Paddy" Ryan, the headmaster at the time, who managed the purchase and transformation of the site. The pavilion replaced an earlier pavilion opened in 1960 (see below). In 2012 the Cage was refurbished into an Astro turf field suitable for playing rugby and soccer in all weathers and conditions.
