Park Island is Napier's largest sports reserve and is the home of the Napier Rovers Football Club, Hawke's Bay United, Napier Old Boys' Marists Rugby Club (with its affiliated clubs of Old Boys' Marist Cricket, Marist Netball, Marist Soccer and Marist Softball) and the Hawke's Bay Hockey Association.
The sportsgrounds have been developed with a high level of intrastructural services, especially efficient stormwater drainage and water reticulation. The grass surfaces provide a consistently high level of playability and availability.
The grounds are divided into areas identified with specific sports or groups of sports. Screened grounds on the park leased to sports organisations for their sole use are Tremain Field (rugby), Napier City Rovers (football) and the Hawke's Bay Hockey Association (hockey), which has two artificial playing fields with a third approved and currently in planning.
Park Island also contains Shrimpton Field, which is used for football in winter and cricket in summer, and Bond Field, which has both rugby and football pitches in the winter. These facilities regularly host major football tournaments at inter-school, age groups and inter-federation level.
There is also an archery ground between the two cemeteries and a floodlit training ground south of the Napier City Rovers ground. The park area is used for cross country running, principally at school level.
Large changing room blocks with full shower and toilet facilities are provided on Shrimpton Field and at the screened grounds.
The active sports areas are flanked by a fitness trail and a walkway network that takes in the former "islands".
Clyde Jeffery Drive provides good access to the park, and extensive car parks serve Tremain and Shrimpton Fields and the Napier City Rovers and Hawke's Bay Hockey facilities.
Council's long-term aim is to develop the Park Island reserve as a top-class facility for a wide range of sports. Paddocks between the Taipo Stream and Oak Road, an area south of Bond Field and an area north of the existing grounds and cemetery hills are in planning for further development.
