Grown in a clean and pure environment with world leading food safety programmes, consumers of New Zealand Greenshell™ Mussels can be assured they are eating one of the safest mussels in the world.

Top Environmental Rating

The New Zealand Greenshell™ Mussel Environmental Code of Practice directs best industry practices throughout the growing and harvesting cycle to minimise potential effects on the environment. As a green food source, Greenshell™ Mussels take all their required nutrients from filtering sea water. Nothing else is added. Also as they filter the water around them, their presence actually enhances the ecosystem. So it’s not surprising that New Zealand Greenshell™ Mussels are commonly referenced as one of the best sustainable seafood options.

Quality Assured

New Zealand operates one of the strictest quality assurance programmes for shellfish in the world. Water quality is rigorously and constantly monitored with testing carried out to specifications and standards set by the U.S Food and Drug Administration, European Union and NZ Food Safety Authority. Under this stringent monitoring programme, no product can be harvested from farms without confirmation that the water and shellfish testing during the growing cycle and environmental monitoring have declared it safe.

New Zealand Greenshell™ Mussels are processed in state-of-the-art factories operating under stringent hygiene and quality control regimes adhering to New Zealand government regulations and international food processing standards including the USFDA (meeting all requirements of the National Shellfish Sanitation Program) and European Union. Regular audits are carried out by Ministry inspectors as well as buyer appointed auditors. Each factory runs its own quality control program including a Hazard Analysis Critical Control Point (HACCP) plan.


New Zealand Greenshell™ Mussel products are highly traceable.  Any packaged product in the market can be traced from when the product was harvested and processed, right back to the time it was seeded out as a juvenile mussel.

Highly Nutritious


New Zealand Greenshell™ Mussels are the ultimate health food. High in protein, low in fat yet providing 680mg of omega-3 from EPA and DHA in one serving. They are also a rich source of selenium, iron, Vitamin B12 and iodine, and a good source of magnesium and calcium.

  • Five New Zealand Greenshell™ Mussels provide almost 100% of your daily iodine and selenium needs, 1/3 of daily protein needs and almost three times your daily Vitamin B12 needs.
  • New Zealand Greenshell™ Mussels contain over three times the haem iron (the most easily absorbed iron form) of rump steak, on a per gram basis. Six medium sized mussels provide over 100% of the recommended iron intake for men, and around 48% of a womens daily iron requirement.

Product Forms

New Zealand Greenshell™ Mussels are available in different product forms:

  • The predominant form is IQF Half Shell (individually quick frozen on the half shell). Snap frozen within hours of harvest ensures the fresh, straight from the water taste of the mussel is encapsulated in the freezing process.
  • Mussel meat including marinated and smoked variations.
  • Freeze-dried powder format used in neutraceutical products, recognised as helpful for joint mobility and promoting general well being.

Culinary Benefits of the IQF Half Shell

  • Individually quick frozen on the half shell within hours of harvest to capture that fresh, straight from the water taste.
  • A sweet mild flavour which compliments many cuisine styles and applications.
  • The distinctive emerald shell adds extraordinary visual appeal to a plate.
  • Reduced waste – only one shell to discard, thaw only what is needed.
  • The high meat to shell ratio both enhances your customer’s value perception and requires fewer shells for an impressive display, reducing plate costs and increasing margins.
