North Kaipara Barrier is formed by sediments, mainly estuarine and dune sands of the Kaihu Group, deposited in a major cycle of transgression (subsidence) and regression (uplift) during the Quaternary. Hautawan, Okehuan and younger lignites along with terrace surfaces at 105 m, 67 m, 40 m, 24 m, 8 m, and 4-2 m a.s.l., which can be correlated with dated surfaces elsewhere in the North Island, provide chronologic control. Five units, the Hautawan Dargaville Formation, Nukumaruan-Castlecliffian Rototuna Formation, Castlecliffian-Hawera Pareotaunga Formation, Hawera South Head Formation, and the Hawera Shelly Beach Formation, are present. -from Author
