Head of sponsorship at ANZ Sue McGregor said James was one of 27 kids being selected to take part in the pivotal prematch moment during this year's summer of cricket.
"We hope that connecting young players with their heroes will help inspire the next generation of Kiwi cricketers," she said.
"There's a magic that happens when fans take part in the match and meet these great players. We try to get these young cricketers involved as much as we can."
The ANZ coin toss activity is part of its support for cricket at all levels in New Zealand.
The Black Caps took out the match at Cobham Oval by five wickets in the first of three ODIs between the sides.
