His brother-in-law responds: "But Fonterra is owned by its farmers. 10,500 farming families. That's a big team, bigger than the 15 you're used to."
In another video, Hawera farmer Simon says New Zealand's dairy farmers are punching above their weight.
"We're a lightweight with some big gloves on.... And at 4.30 in the morning you're getting up to do your best for your country."
The videos discuss topics of science and innovation on farms, farmers caring for the environment, and why McCaw was helping Fonterra with the series.
"We grew up on a farm, so I understand farming and from what I've seen, Fonterra is a great story," McCaw says. "It's a great story that I think Kiwis should all be proud of."
"I want people to understand the kind of things that happen [on farms] and the great people, the farmers that own Fonterra that they care about what they do, they love what they do, they love New Zealand and they want to do it right."
McCaw has been a brand ambassador for Fonterra since 2012.
