"We're going to keep the ball in a box so I can have it forever," he said.
The ball was signed by Williamson and is a lasting memory of his first-ever test match at Bay Oval.
Ethan now has a summer filled with cricket to look forward to, including a tournament coming up in the New Year.
ANZ head of sponsorship Sue McGregor said Ethan was one of 22 promising young
cricketers chosen to take part in the pre-match custom this cricket season.
"After such a tough year it has been even more apparent the important role that sport and
our sporting heroes play to inspire our future generations," she said.
"We are so pleased to be able to continue creating these once in a lifetime opportunities for our future Black Caps and White Ferns. Getting to meet their heroes is something we hope will stay with them for years to come."
The coin toss experience is part of ANZ's long-standing support of Kiwi cricketers.

addition, ANZ has donated $1m in grants to grassroots cricket and netball clubs to
help them get back up and running after Covid-19.
