He said they were light on numbers going into the tournament, taking 10 girls to Cambridge when the other teams had 12.
"We were already short a few players then we lost one of the girls in the first game to injury, then another in the next game.
"It was pretty tough with only eight girls in the last two games but they did well considering. We were the only ones that struggled for numbers like that."
The Bay men's team also struggled during the tournament, losing all their matches to finish last. However, the men's team get direct qualification to the nationals as hosts.
Fleming said they only had two girls in the squad this season who featured in the team which qualified for the semifinals at nationals earlier this year.
He said the management and coaching group would look at ways to better identify girls in the future, who want to play sevens in the Bay. He said a lot of girls want a break after a long 15s season which made things difficult.
The Bayleys National Sevens tournament is being held at the Rotorua International Stadium on January 16-17 featuring the best provincial teams in the country.
