One division of the group, Emerald Foods, won the New Zealand Trade and Enterprise International Business Award last year for companies with a turnover of between $10 million and $50 million.
She is a former deputy of the Business Roundtable, and was named New Zealand Ernst & Young Entrepreneur Of The Year in 2009.
She has also worked with a number of charities.
Her extensive and successful business career aside, Foreman told the Weekend Herald she regrets not spending more time with her children.
"It's really very difficult to be a mum and a businesswoman. You just do what you can do. I've been really fortunate, I've had a lot of help but it's really hard," she said.
"I gave the business probably more dominance than it should have had. I should have spent more time with my children."
The fact that her personal relationships have been the subject of much media speculation is another example of the struggle women in business face, she said.
"A male in my position would have never had the same attention, that's why it's hard for women. I've had some wonderful people in my life ... but if I was a man no one [in the media] would be very interested."
