Both companies could see the growth opportunities within the targeted nutrition market, Wickham said.
Over the past 18 months, Foodspring had become the fastest growing targeted nutrition brand in Europe, he said.
At the same time, the partnership gave Fonterra immediate and direct access to the fast-growing consumer sports and active lifestyle segment, he said.
Wickham said sports nutrition was no longer about professional athletes or bodybuilders.
"This continues to be a really attractive market for our dairy protein and dairy speciality ingredients and we will keep up the momentum in this market," he said.
Wickham said Fonterra would continue its relationship with Foodspring and its new owners Mars - an NZMP customer.
Goodminton AG is a venture capital-backed holding company that specialises in sports and lifestyle nutrition brands.
Fonterra is in the throes of selling assets to reduce debt by $800 million.
Last month, the company sold its icecream unit Tip Top to global dairy giant Froneri for $380m.
