Long Bay-Okura Marine Reserve, Nature reserve in Hibiscus and Bays, New Zealand.

This marine reserve covers approximately 980 hectares along Auckland's northeastern coast, protecting diverse coastal habitats including sandy beaches, rocky reefs, estuarine mudflats, and mangrove forests near the Okura River estuary.

The reserve was created by Order in Council in 1995, covering 980 hectares at Long Bay on Auckland's North Shore. Its shoreline adjoins the Long Bay Regional Park and the Okura Estuary Scenic Reserve, so the protected waters sit directly against land already set aside as park and scenic reserve.

The reserve's name comes from its two adjoining shorelines: Long Bay, the beach at the southern end of Long Bay Regional Park, and the Okura Estuary, which the Okura Estuary Scenic Reserve borders. Visitors walking the shoreline pass from sandy beach into estuary mudflats within a short distance.

Located just 20 kilometers north of Auckland with public transport access and visitor facilities at Long Bay Regional Park, the reserve strictly prohibits fishing, collecting marine life, and disturbing protected species.

The reserve's 980-hectare area was fixed by Order in Council in 1995, and its seaward boundary follows the shoreline of Long Bay Regional Park and the Okura Estuary Scenic Reserve, so the protected edge is walked by visitors on land.
