Marine reserves are designated areas of territorial seabed and foreshore where human exploitation, such as fishing and gathering, is strictly prohibited. Managed by the Department of Conservation (DOC), these reserves safeguard biodiversity, protect breeding stocks, and maintain genetic diversity across marine species. Covering 7% of territorial waters, they serve as natural laboratories for research, educational hubs for understanding marine ecosystems, and offer recreational opportunities for public enjoyment while preserving these crucial habitats for future generations.

  1. Management practices

  2. Marine Reserves • Particular areas of territorial seabed and foreshore.

  3. Marine Reserves • Particular areas of territorial seabed and foreshore. • In these areas there is no fishing, no shellfish or seaweed gathering, no other human exploitation.

  4. Marine Reserves • Particular areas of territorial seabed and foreshore. • In these areas there is no fishing, no shellfish or seaweed gathering, no other human exploitation. • Managed by DOC, and they are also responsible for looking after sea mammals.

  5. Marine Reserves • Particular areas of territorial seabed and foreshore. • In these areas there is no fishing, no shellfish or seaweed gathering, no other human exploitation. • Managed by DOC, and they are also responsible for looking after sea mammals. • We have 18 marine reserves protecting 7% of territorial waters.

  6. Should include: • Large, pristine natural areas

  7. Should include: • Large, pristine natural areas • Contain breeding stock, and genetic reserves

  8. Should include: • Large, pristine natural areas • Contain breeding stock, and genetic reserves • Also act as controls for measurement and management practices.

  9. Should include: • Large, pristine natural areas • Contain breeding stock, and genetic reserves • Also act as controls for measurement and management practices. • Viable examples of every ecosystem and community (like living ‘museums’)

  10. Should include: • Large, pristine natural areas • Contain breeding stock, and genetic reserves • Also act as controls for measurement and management practices. • Viable examples of every ecosystem and community (like living ‘museums’) • Recreational reserves – public access for non-exploitive recreation, eg sailing, swimming etc.

  11. Reasons for marine reserves • Aesthetic and moral – we have a duty to preserve it for our children yaddayadda

  12. Reasons for marine reserves • Aesthetic and moral – we have a duty to preserve it for our children • Recreational – important for people to see animals in a natural environment, and to interact with them in a positive way

  13. Reasons for marine reserves • Aesthetic and moral – we have a duty to preserve it for our children yaddayadda • Recreational – important for people to see animals in a natural environment, and to interact with them in a positive way • Educational – to teach people about the sea and the coast, and for research

  14.

  15. Reasons for marine reserves • Aesthetic and moral – we have a duty to preserve it for our children yaddayadda • Recreational – important for people to see animals in a natural environment, and to interact with them in a positive way • Educational – to teach people about the sea and the coast, and for research • Breeding grounds – allows organisms to reach reproductive size easily, and offspring to survive to reproductive age. Maintains stock of organisms.

  16. Reasons for marine reserves • Protection of rare and endangered species or habitats

  17. Reasons for marine reserves • Protection of rare and endangered species or habitats • Habitat conservation – preserve area that is natural and contains rare and unusual species.

  18. Reasons for marine reserves • Protection of rare and endangered species or habitats • Habitat conservation – preserve area that is natural and contains rare and unusual species. • Genetic conservation – retain genetic diversity among a species, to keep breeding groups healthy. Preserves organisms that have a future role in pharmaceuticals or bioengineering.
