Cornwallis Beach is a sheltered swimming beach on the Manukau Harbour side of Auckland, reached from Firebreak Road and Pine Avenue in Cornwallis. The beach is popular with swimmers, fishers and small boats, and it has no large waves, though currents can be strong near the wharf, especially at high tide.
Pedestrian access is open 24 hours a day. Vehicle gates open from 8am to 9pm in summer daylight saving and from 8am to 7pm in winter. The main carpark is at the Pine Avenue entrance, with an overflow area, and there is more parking at the Firebreak Road entrance. The beach is a designated dog walking area, where dogs can walk on a lead along the sand but should not roam the grassed picnic areas. Two picnic sites with gas barbecues can be booked up to seven months ahead, and each fits up to 60 people. The wharf has recently been repaired, with new handrails, floorboards and two new sets of stairs to the water.
