Residents have vented their anger at several heated public meetings, and local businesses have threatened to ban Wilson from their stores if authorities continue with plans to house him in Wanganui.
The Corrections Department has said Wilson, known as the Beast of Blenheim, would be subject to the strictest conditions of any person ever released from prison.
He will be one of the first fitted with a GPS tracking device, which will alert authorities when he moves into restricted areas.
"But still we don't have the confidence that we wanted ... what if it [the GPS] fails?" Ms Main said.
The community has voted to fund a judicial review of the parole board's decision to relocate Wilson to a house on the Wanganui prison grounds.
"We haven't got enough information, we weren't given this information in time, we weren't able to discuss it and we weren't able to come up with the confidence that this would work," Ms Main said.
"At this moment we're actually not accepting this is going to happen."
