The Dunedin men's team has been the best-performed centre team in the event, which started in the early 1970s, but the women have always struggled.
"They are capable of performing better," Hynes said.
"But the North Island teams are very strong.
"A lot of it is mental. Our players lack belief in themselves and get overawed and psyched-out when playing North Island teams."
Hynes plans to discuss the issue with her fellow selectors and could seek the help of the New Zealand Academy of Sport South Island to solve the problem.
"We will probably need to get professional advice to give our players a belief in themselves," she said. Hynes also feels it is necessary is to establish compatibility in the team.
"We must get the combinations right," she said.
"If there is not compatibility in the team you are on the back foot from the start."
Hynes (70) has come into her new role after a 12-year apprenticeship in centre teams.
She started bowls 16 years ago.
She is a member of the St Clair club and has won 13 Bowls Dunedin titles.
She needs two more titles to get a second bar for her gold star.
Hynes also won a New Zealand fours title when the championships were held in Tauranga in 2003.
"I'm still competitive myself and would like to get this instilled into the women's team," she said.
Hynes pulled out of all representative games last season.
"I have done that and amnot interested in playing inter-centre bowls any more, but I want to give something back and stay involved."
Fellow St Clair club member Bob Crawford is the other new selector voted on to the five-person panel.
The panel is: Hynes, Crawford, Pat O'Dea (Kaikorai), Neil Williams (North East Valley), Tasma Burton (Port Chalmers).
