Muriwai is a beach and village on the west coast of the Auckland Region of New Zealand, popular with people from Auckland, 42 km away. The beach runs northwards for 50 km to the mouth of the Kaipara Harbour; the northern part is known as Te Oneone Rangatira Beach. The beach has black ironsand. At the southern end, where the village is, the beach ends at Otakamiro Point. South of the point is a small bay, Maukatia or Maori Bay. Muriwai Regional Park, administered by Auckland Council, includes public areas around the main entrances to the beach, Otakamiro Point, Maukatia, the golf links, and the southern 8 km of Muriwai Beach.
From Auckland take the Northwestern Motorway then continue on State Highway 16, turning off at Waimauku onto Muriwai Rd.
4WD vehicles and motorcycles are permitted to drive on the hard sand of Muriwai Beach and Te Oneone Rangatira. Road rules apply. Access points are from Coast Rd at Muriwai and Rimmer Rd in Woodhill Forest near Helensville. The speed limit is 30 kph south of Okiritoto Stream, and 60 kph north of the stream. Drive with headlights on. Access to the northern beach is only within three hours either side of low tide. Be wary of soft sand, tide surges, sweeper waves and, of course, the incoming tide.
- Gannet breeding colony on Otakamiro Point, nearby Motutara Island, and Oaia Island, 1.6 km out. There are viewing platforms and information panels about these beautiful seabirds. The birds return here between Jul and Oct and lay eggs around Oct–Nov. The colony is deserted in late autumn and early winter. This is the most easily-accessible gannet colony in New Zealand.
