The lambs were bred in the South Island hill and high country and brought down to graze selected chicory and chicory/red clover pastures.
About 30,000 lambs had reached the programme's criteria for Omega-3 intramuscular and polyunsaturated fats this year.
Omega Lamb Project general manager Mike Tate said New Zealand lamb was internationally renowned for its quality by consumers and the hospitality industry.
However, Te Mana Lamb was ``something different'' and the specific breeding programme and pasture requirements did not lend themselves initially to mass production.
"At this stage, it is very much aimed at the fine dining experience,'' Mr Tate said.
There had been an "extremely positive'' response from chefs and feedback from multiple taste panels showed the extra "good fats'' enhanced succulence and eating quality, he said.
Alliance Group general manager marketing Peter Russell said the project revealed ``a very promising premium future'' for farmers.
The project was touted as having the potential to add more than $400 million in new export earnings and increase lamb revenues by 34% for adopting farmers.
