Medlands Beach, Beach in Great Barrier Island, New Zealand

Medlands Beach is a 2.1-kilometre sweep of white sand on the shore of Oruawharo Bay, on the east coast of Great Barrier Island, directly south of Kaitoke Beach with the Sugar Loaf hill and Pitokuku Island in between. Memory Rock, also called Medlands Rock, sits halfway along the beach and has a short informal track to its summit. The settlement's permanent houses and holiday baches stand behind the dunes or on higher ground.

In November 1888 photographer Henry Winkelmann bought 200 acres (81 ha) at Medlands Beach and named the property Ti Tree Flat. The settlement later grew around permanent houses and holiday baches, some tucked behind the dunes and others raised for a view. St John's Community Church, the island's only traditional church building, serves the community ecumenically.

St John's Community Church is the only traditional church building on the island and serves people from different faiths. It remains central to the spiritual life of the local community.

Medlands is a 4-kilometre drive from Great Barrier Aerodrome and Claris, where a general store, New Zealand Post shop and petrol station are found; the settlement itself has no grocery stores or food retailers. The beach runs 2.1 kilometres and can be walked both ways in about 90 minutes. The Department of Conservation campsite at the south-eastern end takes up to 120 people from Christmas until mid-February.

Shark Alley, at the south-eastern end of the beach, is a sheltered spot used for swimming and for launching boats. A small stream nearby is home to several pāteke, the brown teal ducks. The Department of Conservation campsite there takes up to 120 people from Christmas until mid-February.
