The New Zealand government and Kāi Tahu have formally established Te Au Roa o Te Rakihouia, a strategic network of five marine reserves along the Otago coastline. Created on May 28, 2026, and officially effective as of July 1, 2026, this network covers approximately four per cent of the Otago coastal marine area.
The initiative is the result of a decade of policy development that began in 2014 via the South-East Marine Protection Forum. The management structure is a co-governance model between the Department of Conservation (DOC) and Kāi Tahu, recognizing rakatirataka (authority) and kaitiakitaka (guardianship) under Te Tiriti o Waitangi.
Protected Zones and Ecosystems
The network is designed to protect a diverse array of habitats rather than a single ecosystem. The five reserves safeguard river mouths, estuaries, sandy beaches, volcanic cliffs, and offshore seabird sanctuaries, as well as specialized canyon ecosystems and large kelp forests.
As these areas are designated as marine reserves, they carry the strictest protection levels in New Zealand. The extraction of any marine life is prohibited, and any activity that damages natural habitats is banned. However, non-extractive recreation remains permitted.
Governance and Indigenous Integration
Management is shared across the takiwā of Kāi Tahu Whānui, encompassing the rohe moana of several groups, including Te Rūnanga o Moeraki, Te Rūnaka o Ōtākou, Kati Huirapa Te Rūnaka ki Puketeraki, Te Rūnanga o Arowhenua, Te Rūnanga o Waihao, and Āwarua Rūnanga.
Operational oversight is conducted by joint DOC and Kāi Tahu rangers. This partnership ensures that mātauraka (traditional knowledge) informs ecological monitoring and surveillance alongside Western scientific research.

Traveler Logistics Guide
From a ground-level perspective, navigating the Otago coast now requires a strict adherence to "look but don't touch" policies. For those planning transit through these waters:
- Vessel Navigation: Boating is permitted, but operators must ensure anchors do not damage kelp forests or bryozoan thickets. Use designated mooring areas outside reserve boundaries where possible.
- Wildlife Interaction: The area is a critical habitat for the hoiho (yellow-eyed penguin), toroa (northern royal albatross), and pakake (New Zealand sea lions). Maintain official DOC-mandated distances to avoid disturbing nesting or hauling-out sites.
- Permit Requirements: While general swimming and diving do not require permits, organized commercial tours should verify current DOC guidelines regarding group sizes to minimize ecological footprints.
- Customary Access: Be aware that certain areas may be used for organized wānaka (traditional learning). Respect signage indicating cultural activities in progress.
Infrastructure Impact Assessment
The establishment of Te Au Roa o Te Rakihouia shifts the regional tourism model from high-volume extraction (fishing/harvesting) to high-value conservation tourism. By protecting 308 sq. km of waterways, New Zealand is creating a biological baseline for the southeast coast of Te Waipounamu.
This network is a precursor to a larger proposed system that will include five Type 2 marine protected areas and a specific kelp protection area under the Fisheries Act. This phased approach ensures that regional connectivity is maintained while biodiversity is prioritized, potentially increasing the long-term viability of wildlife observation charters in the Otago region.
