East Coast Bays is the collective name for a series of small suburbs of North Shore City, in the Auckland metropolitan area of New Zealand, which line the northeast coast of the city along the shore of the Hauraki Gulf and Rangitoto Channel. Prior to the 1989 local body reforms, the area was a city in its own right, known as the City of East Coast Bays.
The suburbs, from north to south, include Long Bay, Torbay, Browns Bay, Rothesay Bay, Murrays Bay, Mairangi Bay and Campbells Bay. They stretch for nine kilometres from Castor Bay, Milford, at the northern end of Lake Pupuke to Toroa Point, at the northern limit of the contiguous Auckland urban area.
Within the area of the East Coast Bays are numerous high schools, including Long Bay College and Rangitoto College, the largest high school in New Zealand with over 3,000 students between Year 9 and Year 13 of their schooling ('Form 3 to Form 7') attending in 2004.
East Coast Bays is also the name of an electorate from which an MP is elected to serve in the New Zealand Parliament. Its current MP is Murray McCully.
