Mr Marr said the team would tour Kandy, Hikkaduwa, Hambantota and Colombo from April 2.
"This trip is not just about cricket. This is about giving young people an opportunity to experience a foreign culture, to test themselves under extremely demanding conditions, and to hopefully give them an understanding of the world, and of how lucky they are to be living in this beautiful country with all the benefits that we have here," he said.
The expectation was to continue the trip every second year, he said.
Chamodh, 16, can't wait to fly into a familiar territory.
"It's really helpful for emerging players to play among different cultures and in a foreign environment ... teaches us how to adapt to new conditions and to play with different people," he said.
On spending about four days in his home district, Colombo, he said: "It's great. I've been looking forward to that for a while and it should be a great experience for my family from both my father's and mother's sides to come and watch me play."
Chamodh said it would be an honour to play on renowned grounds that have hosted many test and one-day internationals, like Galle Stadium. While he is passionate about playing in Sri Lanka and cheering for the country, he harbours an ambition to be a Black Cap in the future but dreads facing the country of his birth.
"I want to go to the highest point I possibly can in cricket. I want to train every day and give 100 per cent towards achieving my goal," said the Whangarei Boys' High School student.
-The touring team is: Matthew Lobb, Chamodh Peiris, Shane Burton, Matthew Kingi, Jarod Ross, Hamish Kidd, Sean West, Liam Jones, Dante Mitchell, Quinn Pooley, Owen Arthur, Connor Wilson, Shaun Beamish, Shannon Kloppers.
