Meanwhile, Caleb's mum, Chris Anstis said it was a lovely gesture to get people to sign the flag which will hang in the Kiwi team base throughout the games.
"It's fantastic. It's good support for them," she said.
Shoppers to the store were invited to leave messages of support on the flag for the team which will fly pride of place. Masterton Countdown was one of 10 stores offering customers the chance to leave a message.
Countdown is a supporter of the Kiwi contingent going to the games as well as the 2016 New Zealand Olympic team.
Countdown managing director Dave Chambers said the business was proud to be the official partner of the New Zealand teams.
"This is just the start of our partnership with the New Zealand Olympic Committee and we're excited to be supporting our athletes at the Commonwealth Games in Glasgow, and beyond this, the 2016 Olympic Games in Rio."
He hopes everyone will support the team as they prepare to leave for the Games.
