The board's area takes in the top of the North Island and is located north of a line from the Kaipara Harbour mouth in the west across to the Mangawhai Harbour in the east. It includes groups of offshore islands, the Hen and Chickens, and Poor Knights. Although the Te Hiku o Te Ika Conservation Board sits above it, Te Rūnanga Papa Atawhai O Te Tai Tokerau/Northland Conservation Board still manages the coastal area around Te Hiku's rohe.
