Marine monitoring is now underway across the Hauraki Gulf/Tīkapa Moana, marking the first year of new protections aimed at restoring the health and mauri of one of Aotearoa’s most significant coastal environments.
The Department of Conservation has begun surveying reefs and seafloor habitats both inside and outside newly established marine protected areas. The work is being carried out in partnership with mana moana, universities, and research institutes, establishing a baseline to track the condition of the marine environment over time.
The monitoring programme is designed to assess ecological health, measure the effectiveness of protection measures, and understand the impact of any ongoing activities within the Gulf. The findings will form a critical benchmark for future comparisons, providing insight into how marine ecosystems respond to reduced pressure and restoration efforts.
The new protections include 12 high protection areas, which differ from traditional marine reserves by focusing not only on preservation but also active restoration. This includes initiatives such as reseeding shellfish beds and managing species like sea urchins to support ecosystem recovery.
Scientists are studying a wide range of marine life, including reef fish, lobster species, scallops, and key seafloor organisms such as horse mussels and rhodoliths. A mix of methods is being used, from diving and lobster potting to underwater cameras that record fish populations and behaviour on the ocean floor.
The work highlights the importance of reefs and shellfish beds as breeding and shelter areas for marine species, with protections aimed at supporting biodiversity and long-term sustainability.
Early observations indicate strong compliance from fishers respecting the new rules, helping reduce pressure on marine life and allowing populations to recover.
Data collected through the programme will be analysed and reported on over the coming year, with legislation requiring public reporting on environmental changes every five years.
The monitoring marks a significant step in understanding and protecting Tīkapa Moana, with long-term goals focused on restoring balance, strengthening ecosystems, and safeguarding this vital taonga for future generations.
