Ōrewa River

The Ōrewa River is a river of the Auckland Region of New Zealand's North Island. It flows east to reach Whangaparāoa Bay just to the north of Whangaparaoa Peninsula. The town of Orewa is near the river's mouth.

Geography
The Ōrewa River begins as a freshwater river flowing east through the Hibiscus Coast area. As it reaches the Hauraki Gulf, the river forms a shallow estuary. The river has one major tributary, the Waterloo Creek, and has an island in the river estuary, Te Motu-o-Marae-Ariki, also known as Crocodile Island.

History
The Aotoetoe Portage allowed waka to cross between the Kaipara Harbour in the west to the Hauraki Gulf, via the Kaukapakapa River. A similar portage linked between the Kaukapakapa River and the Weiti River to the south.

Amenities
