The offender needed to live somewhere and was at a lower risk of reoffending in a close-knit town like Piha, she said.
"I'm a grandmother. I've got three grandchildren. I can tell you there are people in all sorts of different communities who are on parole for sex offences who we don't know about and we will never know about. Wouldn't you rather be informed? People say 'how can you support him'.
" I don't support him, but this guy is safer because we know about him.
"I do not support sex offenders, but I do believe in human rights. People have a right to live somewhere. He's with a relative.
"We have to start doing things a little differently. Let's inform ourselves and calm some of this hysteria down."
The meeting on Sunday will be attended by a principal psychologist from the Te Piriti Special Treatment Unit, where the sex offender completed a course.
Police and probation services will also be on hand.
In an earlier interview with Ms Carroll, the sex offender tried to quell parents' fears.
He said he was reminded every day of the damage he has done to his victim and family.
"Your kids are safe. I have no intention of being a repeat offender," he told her.
However a spokeswoman for the Piha parents group said it was "not right" to have the sex offender living near children in the small community.
He was living near an access-way where children gathered to catch the bus, she said.
Her group was circulating a petition and lobbying Government to have him removed.
"It is just not right... we shouldn't be paroling a child sex offender near a pre-school or beside young people,'" she told Fairfax Media.
'"Our kids roam quite freely. And he is straight along from the pre-school.'"
The sex offender is barred from associating with children under 16 without supervision.
