The school grounds also host numerous sporting facilities, including the Izard Gymnasium, High Performance Cricket Centre, a water surface hockey turf, a full-sized Cross Country Course and many team sports fields. The nearby Whanganui River is used by students for rowing training and competitions; rowing being one of the sports in which Collegiate has traditionally excelled, having won the Maadi Cup 17 times, a national record. The Collegiate women's squad had a particularly strong year in 2006 when it won the most prestigious women's race in the lower north Island, the Levin Jubilee Trophy, for the first time. Unfortunately, such success could not be replicated on the national stage, with the u18 girls eight only managing bronze in the penultimate race of the 2007 Maadi Cup. The school also hosts the nationally popular Whanganui Cricket Festival each year which sees over 1000 cricketers display their skills throughout the month of January.
