''We see our future [here] and it's a lot to do with our past.''
Mrs McCallum Jackson and husband Ian Jackson's pork comes from their pig farm in Hunter near Waimate and processed in their Kaikorai Valley factory.
The pair regained the lease of the Dunedin factory earlier this year from their son, Cain Lindegreen.
Mr Lindegreen had taken a lease on the building in 2014 and managed the factory.
The factory included a shop, which closed late last year.
Mrs McCallum Jackson said the pair were committed to keeping a presence in Dunedin.
The factory is leased until 2024.
Eight staff are employed at the factory, which has been managed by Dee Hayes since November last year.
The Otago Farmers Market was where the pair first started selling pork goods in 2003, Mrs McCallum Jackson said.
She was proud of the support they had built up at the market over the years and wanted to maintain it.
''We have a very loyal following here and we'd never let them down. It'd be over my dead body.''
Their stall is run by a staff member.
Bacon was usually the biggest seller for Havoc Pork Farm at the farmers market, though there were seasonal trends.
''In the wintertime, bacon hocks - we can never do enough - and in the summertime, ribs and sausages are back because people are having barbecues.''
Christmas hams were also popular and they started taking orders in September.
Mr Jackson and Mrs McCallum Jackson live on their Hunter farm, though Mrs McCallum Jackson said she tried to come down to Dunedin ''whenever I can''.
Beginning with selling just one pig's worth of pork products each week at the Otago Farmers Market in 2003, Havoc now sells between 40 and 50 pigs' worth.
Besides the Otago Farmers Market, restaurants, cafes, and supermarkets around the country also stocked Havoc's products.
