Ms Bennett said she was the first to admit things needed to change.
"I am disappointed and horrified when any child is hurt ... are people willing to make sacrifices to bring about change to protect those vulnerable children?"
Ms Bennett said the Government received 160,000 abuse notifications last year, but she believed that was only about half the real figure.
Anne, from the Rotorua Sexual Abuse Centre, said sexual abuse of children often flew under the radar if the offender and the victim were members of the same family, as name suppression was almost always permanent.
"And what do we know about the offenders? We know who the victims are, but we are looking at the band-aid side of the issue."
Abuse was cross-cultural but those with more money were more likely to be able to hide behind the justice system, said Anne.
Lani from Family Focus Rotorua said one of the problems she faced was a lack of information.
"The courts don't share much [information] with me, they just fill in their tick boxes. The more information I can get from [Child, Youth and Family] and the courts, the better," she said.
Sarah, a child protection co-ordinator for the Lakes District Health Board, said often people did not fully understand what child abuse was.
"If a woman smokes when pregnant knowing it's harmful, is that child abuse? What about children not being put in child restraints when in a car?"
Sarah said part of the problem was there was no proper definition of child abuse.
