Ballance, P.F.; Smith, I.E.M. 1982 Walks through Auckland's geological past : a guide to the geological formations of Rangitoto, Motutapu, and Motuihe islands. Lower Hutt: Geological Society of New Zealand. Geological Society of New Zealand guidebook 5. 24 p.
Abstract: The essential features of Auckland's geological history can be seen in walks on Rangitoto, Motutapu, and Motuihe islands at the entrance to Auckland's harbour. This guidebook represents the geology of the Auckland area as seen on the inner gulf islands in relatively non-technical language. It explains the natural forces and processes that have produced the present landscape of the islands, and describes some of the walks which can be taken. These walks serve as self-guided field trips not only for the layman but also for secondary schools or more advanced students of earth science, and are designed to cover the best examples of geological featues and phenomena on the islands.
