"I've always been really focused on quality customer service and have been working hard to develop my accuracy and speed.
"It's really fun going out and spending time with my workmates outside of work and getting to meet checkers from other stores.
"It's a great bonding experience.
"For me, good customer service is about remembering that the few moments I spend with someone can really brighten up their day."
Foodstuffs North Island chief executive Chris Quin said the company had run its Checker of the Year competition for decades, and it is an annual highlight for staff right across the business.
"It's a great opportunity for us to recognise and celebrate the contribution our checkout operators make on the front-line of our business every day.
"Our checkers are the face of our business and their customer service skills are crucial to our success in meeting the expectations of our customers.
"The annual Checker of the Year competition is about acknowledging their skills and creating some friendly rivalry between stores."
While the competition is taken seriously by the competitors, the event also provides an opportunity for them and their supporters to have some fun.
With a 'rock star' theme this year, competitors' colleagues, family and friends donned rock star outfits and cheered them on with banners, chants and store mascots.
The top 12 checkers each received a $50 gift card, with the top three finalists winning extra prizes. There were also prizes for the best dressed team, best supporting teams and best air guitar solo.
As the winner of the Wellington region heat, Vanessa will go on to compete against the winners of the nine other regional heats held over June-July.
Each regional winner will be mystery shopped three times between August and November to determine the overall North Island Checker of the Year winner and two runners-up, which will be announced at the Foodstuffs North Island Excellence Awards in November.
