"We knew these would be the best people to front our campaign. They are our present and future leaders, our motivators and the ones to aspire and encourage good on-court and sideline behaviour," she said, adding that the BOINC had received many complaints in the past about unacceptable sideline and on-court behaviour.
"This is a problem nationwide, but we decided to do something to stop it at our games," she said.
"Our objective is to promote positive, healthy lifestyles for players, officials, tamariki and whanau by enforcing a smoke-free, alcohol-free, drug-free and violence-free environment at our games."
Players and spectators who ignored the rules would be reprimanded within the rules and regulations of the BOINC.
Saturday's launch began with a karakia, followed by the unveiling of the signs and light refreshments, Ms Brophy saying she hoped the initiative would be adopted by other netball organisations in NZ.
