Calvin's Story

You will spot Calvin Opperman, in cloud of delicious smelling steam, as you arrive at Grey Lynn Farmers Market.

Where did you grow up?
In Howick, and I still live there. I went to school at Sancta Maria primary, then St Kentigern College. Sport was a big part of my life growing up — especially football.

You took football seriously?
Yes — serious enough that it took me to Ohio and then Vancouver on football scholarships. I took advantage of the opportunity to study finance while I was there. It was a great experience, and it broadened my horizons.

And when you returned to New Zealand?

I worked for KPMG before joining a workforce company, as the Group Financial Controller, to help a friend with his business.  We help place people into all sorts of jobs — construction, warehousing, logistics, that kind of thing.

What attracted you to Kettle Korn?
I noticed the smell, the sound of popping, and the waft of smoke, at the Howick Village Market. I just had to find it and try it. My kids and I became addicted and went back every week for more.

What made you take the next step to making it yourself?

I loved it so much that I just had to get involved. Kevin talked me through the details and the network. The more I learnt the more I liked the business model.

How is the reality?

I love it. Kettle Korn is so delicious that it makes people smile. The sweet-and-salty balance and the smell are irresistible. People often pause “just for a taste” and somehow leave clutching a warm bag or box. You can hear it popping, see it being made, and then eat it fresh – it’s great fun.

Tell me about your customers?
We’re on the footpath so people sometimes park next to our stall, jump out and get me to re-fill their box. It’s a popular treat for lunch boxes, family movie nights, kids’ sports games, or to share with flatmates and friends. Some people nibble away while they are exploring the market. …and I have noticed some lucky market dogs getting a few Kettle Korn treats too.

What do you enjoy about selling at Grey Lynn Farmers Market?
The people. There’s a real community feel to it. You see familiar faces coming back every week, families catching up - people making it part of their Sunday routine. It’s nice being part of that buzz.

Do you get any spare time?

Saturdays are devoted to my two young boys - I’ve got a five-year-old and a three-year-old. We have a routine of getting out of the house and doing something active like swimming or exploring Auckland on the buses.

And what about for yourself?
I’m into fitness, staying active, and staying healthy. My work mates also value fitness and there’s a gym on-site so it is easy to build exercise into my daily routine. A lot of my social life also involves sport and fitness challenges. That’s why Kettle Korn is my go-to treat - it’s simple, fresh and delicious.
