Mr Bowen and partner Alecia Cole-Bowen run the Three Little Birds truck which specialises in Jamaican food such as jerk chicken and curried goat.
"We started cooking for friends and then our first event was the Newtown festival in Wellington and we were a big hit," Mr Bowen said on a visit to check out the Games Village venue.
"It started as a hobby; now it's a business.
"We have travelled to and participated in some of the biggest festivals in New Zealand, including Womad and Rhythm 'n Vines."
Serving up to 800 meals a day at the three-day Womad music festival gave the couple lots of experience and from there they decided to start running their own events.
Mr Bowen has hand-picked the 12 vendors for the Masters Games who will be rotated with six for the first five days of the Games and six for the last five days.
As well as authentic Jamaican cuisine, food from Spain, Holland, Vietnam, Japan, Greece and other nations will be featured.
Along with breakfast, lunch and dinner, the War Memorial forecourt will offer musical entertainment, while the centre will be used for registrations and merchandising. The concert chamber will host briefings, movies and seminars.
The Masters Games, which started in 1989 and alternate between Whanganui and Dunedin, offers more than 50 sports and will have its official opening ceremony at Cooks Gardens at 6pm on February 3.
Registrations are open for competitors at $60, which rises to $85 on January 14.
