Bay of Islands marine protection is urgently needed

Clear waters - Clean waters - Dynamic waters - Productive waters - Treasured waters


Below are our thoughts on a suite of tools that can begin to reverse the decline in Bay of Islands marine life.

working togetherPhoto: Darryl TorcklerAll of us who love the ocean, let's get together and take on the challenge of marine protection for the Bay of Islands.

We need to make sacrifices to protect what we love and start to reverse the decline.

Future generations must be able to enjoy Tangaroa's abundance.


[panel][heading size="h3" style="module-title"]No-take areas deliver[/heading]

We hope the new marine protected areas legislation contains an option for long term rahui-tapu that can be intitiated by local hapu.

BOI areasThe Bay of Islands rohe moana boundaries

Ngā Hapū o Taiamai ki Te Marangi in the west, and Patukeha and Ngati Kuta hapū of Te Rawhiti, hold mana moana through their gazetted rohe moana areas in the Bay.

Their rohe moana committees are in a  position to bring about change in the way the Bay of Islands fishery is managed.

[panel][heading size="h3" style="module-title"]Manage the fishery for higher abundance[/heading]

higher abundanceLet’s choose to manage our fisheries to have more fish in the sea. Historically NZ's fisheries management decisions have been based on trying to keep fish stocks at just 20% of natural abundance. Managing for 50% natural abundance would mean more fish, bigger fish.

  • Put the big snapper and big crayfish back.  They deal to kina and keep our rocky reefs healthy
  • Catching kingfish, hapuka or bass? Take home just one big fish in total per angler per day
  • Snorkel for scallops, tank dive if you must, but please leave your dredge in the garage.

[panel][heading size="h3" style="module-title"]Dolphins in distress[/heading]

dolphins in distressPhoto: Cat PetersA Massey University report has made the following findings about the Bay of Islands bottlenose dolphin population:

  • Since 1999 the number of local bottlenose dolphin visiting the Bay of Islands has declined by 66%
  • It is suspected 75% of dolphin calves have died before reaching independence.
  • Dolphins spend 86% of daylight hours in the presence of at least one boat.
  • Both commercial and private vessels are altering the behaviours of the dolphins and in particular affecting those behaviours which are biologically critical for their survival.

[panel][heading size="h3" style="module-title"]Take local action to reduce sedimentation[/heading]

siltThis is approximately what 500,000 tonnes of sediment looks like by volume. Enough to create a pile on a rugby field 51 metres high!

graphBreak down of contributors to Bay of Islands sedimentation

  • Approx 500,000 tonnes of silt surges down our rivers to be deposited in Bay of Islands waters every year.
  • That's 2.4mm on the seabed each year.
  • In the last 150 years, sedimentation has been 22 times greater than the last 10,000 years!

It covers shellfish beds, displaces kelp forests, turns rock seabeds to mud, and extinguishes important deepwater habitats.

Where it comes from

  • Native forest and manuka scrubland contribute only 4.8% of the silt, despite being 20% of the land cover.
  • Beef and dairy farming contribute 51.6%.
  • Clear felled pine forests contribute 19%.

Native forest and manuka scrubland contribute a miniscule 24 thousand tonnes, even though they make up 20% of the land cover.

Marine invaders are one of the great threats to the world’s oceans, arguably more sinister than land-based pests.
  • There hasn’t yet been complete eradication of a single marine pest in New Zealand.
  • Marine invaders are typically difficult to detect and monitor.
  • They are usually fast growing, breed prolifically, can survive all sorts of environmental conditions, and have few natural predators.
  • Some are highly competitive, displacing native plants and animals. Others alter the underwater seascape and change the way ecosystems function.
