A GEOLOGICAL LANDSCAPE

The islands of Motutapu and Rangitoto are 'joined at the hip' (by a causeway constructed by US servicemen stationed on the island during WWII) , yet they couldn't be more different. They are a unique combination. Motutapu is Jurassic, sitting on ancient greywacke more than 160 million years old and sedimentary strata some 20 million years old. It is an ancient island dating back to Gondwanaland whereas Rangitoto is NZ's youngest island.
