Te Roroa is a Māori iwi from the region between the Kaipara Harbour and the Hokianga Harbour in Northland, New Zealand. They are part of the Ngāti Whātua confederation of tribes. In the early 19th century Te Roroa fought a series of wars with Ngāpuhi. In 1807 or 1808, following earlier battles, the Ngāpuhi chief Pokaia led a campaign against Te Roroa. Te Roroa, led by their chief , and their Ngāti Whātua allies led by Murupaenga ambushed and defeated the Ngāpuhi forces in the Te Kai-a-te-karoro battle at Moremonui.
