A new production line at the North Island Mussels plant in Greerton is processing 6000 pottles of marinated mussels a day.
About 30 per cent of the pottles are exported to Australia, in addition to the 50 tonnes of frozen half-shell mussels exported from the company each day.
The marinated mussels production line was transferred by owner Sealord to Tauranga from Nelson late last year after formation of a new amalgamated company.
North Island Mussels was formed by Sealord and Sanford in October following the receivership of the company formerly known as North Island Mussel Processors Ltd (NIMPL).
With its financial woes behind it, the new company was able to take over the management of Sealord and Sanford's mussel farming operations in the Coromandel, and add the new production line at the $23 million Tauranga plant.
