Most teams who entered in 2019 returned this year, along with several newcomers.
"The impact of Covid has had a terminal effect on many outstanding events both here in Aotearoa and abroad, so we're both very grateful and hugely excited to be able to resume the festival this year.
"It is an opportunity for teams and their supporters to reconnect and rekindle friendships forged at previous tournaments, and meet new members of our whānau who will be attending for the first time."
Campbell said in keeping with the Global Games ethos, the focus of the festival was less about competition and more about enjoyment, sportsmanship and the opportunity to participate in a major sports tournament.
For many it would be the biggest stage they have played on.
"Regardless of whether players are playing in their very first season of rugby, or are destined for the All Blacks, our mission at Global Games is the same: to provide every player with a positive world-class experience that will last them a lifetime.
"The chance to go on tour with their teammates will be a once-in-a-lifetime opportunity for some of these kids, as touring is usually reserved for elite players selected for representative duties.
"For many, just having the experience of being on a bona-fide rugby tour will be something they remember forever."
The New Zealand Junior Rugby Festival was being held at Owen Delaney Park, with the opening ceremony at 4.30pm on Thursday, September 15.
Games kick off at 9am on Friday and run until 2.30pm on Sunday.
