The inaugural competition will be contested at Owen Delaney Park over two weekends, the first series of games to be played this weekend.
The second series of games, which will include the playoffs and finals, will be played on November 15-16.
Teams have been drawn from five parts of New Zealand, roughly based on Super rugby franchises.
The tournament is expected to be a step up from provincial sevens. National sevens coach Sean Horan said it was a valuable opportunity to broaden the talent pool and would be a good platform for players to push for selection into the New Zealand squad.
The side from the southern South Island will be called Southern Ti Kouka and has a mixture of established rugby players, players from other sports and some schoolgirls.
The team will be coached by experienced sevens coach Mike Moeahu, who said the side had not had a chance to train together much but all players had been on individual programmes.
The side will be captained by Otago inside back Kelly Brazier, who is a contracted sevens player with the national union.
She is living in Tauranga amd training with the national squad but has linked back with the southern side for this competition.
Moeahu expected the competition to be tough.
It was a good chance for players to see what level was expected to play for New Zealand and there was plenty of emphasis on speed.
The idea of the tournament was to improve the standard right across the country.
Joining Brazier in the southern side are established Otago Spirit players Angie Sisifa, Greer Muir, Victoria Subritzky-Nafatali and Rebecca Todd.
Lucy Anderson, a former Spirit player who now plays for Canterbury, will also turn out for the team.
Dunedin netballer Renaye Flockton is in the side, as are South Otago products Samara Hollows and Mikayla Latta.
Pip Symes, who played for the Otago sevens team over the past couple of years and is a national youth hockey representative based in Auckland, is also included.
Those from Southland include national youth touch player Courtney O'Callaghan, former representative rugby and touch player Brianna Brockliss-Lodge and former Southland Girls' High School player Laura Buckingham.
In the first week, absentees will include Sisifa, who has an injured shoulder, while Symes has a nagging groin problem and will not play.
The five teams will play each other this weekend, while at the finals weekend, teams from Bay of Plenty, Waikato and a high school team from the Taupo area will be involved.
The South Island regional sevens competition for both men and women will be played in Timaru on December 13.
