The defender/holding midfielder, who plies his trade in Italy with Series B promotion contenders Vicenza Calcio, was excited about the games to come.
"Our training and our warm-up games have made us all feel pretty prepared and ready for the first game," Edge said.
"We were [welcomed] on to a marae this week which was very special for me because I am part-Maori so to connect back with my roots was special.
"There is a very good atmosphere around the team and the hotel. All the boys are very tight. We are feeling very confident about getting a result in that first game."
Interest in the U-20 World Cup is intensifying with more than 20,000 tickets already sold for today's opening game between New Zealand and Ukraine.
Edge has been a consistent starter in Daren Bazeley's team in this month's warm-up games, playing across the back four positions in partnership with team captain Bill Tuiloma.
"This is my third World Cup involved with Bill. He is a good leader and his experience with Olympique Marseille and being an All White helps us all.
"He is someone to look up to and is a good role model," Edge said.
