Ninety Mile Beach is located on the western coast of the far north of the North Island of New Zealand. It stretches from just west of Kaitaia towards Cape Reinga along the Aupouri Peninsula. It begins close to the headland of Reef Point, to the west of Ahipara Bay, sweeping briefly northeast before turning northwest for the majority of its length. It ends at Scott Point, five km south of Cape Maria van Diemen. It stretches 60 miles and is a designated road.
