Those who get a thank you e-card can then enter the monthly draw to win $500 worth of merchandise for themselves or their team.
This can be anything from netballs, rugby balls, soccer balls, team medical kits, cones and clothing. There will be 34 winners every month including at least one winner from the Wanganui region.
Silver Fern Katrina Grant has been named as the Sport Maker Ambassador.
"I wouldn't be where I am today without the help of a huge bunch of volunteers, going right back to my first day putting on a netball bib," said the Commonwealth Games gold medallist.
"Even at an elite level we rely on volunteers to make our games possible, with members of the score bench just one example.
"I'll be firing off plenty of Sport Maker thank you e-cards and I urge everyone involved in sport to do the same through www.sportwanganui.co.nz."
