They have seen a face at the window of Wilson's unit, which is segregated from the other self-care facilities. The identity of the person at the window was not clear.
People in the neighbouring self-care facilities appeared unconcerned and were seen having a barbecue and sunning themselves on the deck
The Parole Board was to meet this morning to consider a revised reintegration plan for Wilson, including whether two minders need to be present every time he leaves his house.
The conditions will be finalised today, said a spokeswoman. It is expected an announcement will be made about 4pm.
Corrections announced it would hold a press conference at 11.20am at the prison.
Last night the Wanganui District Council said it would co-ordinate a community "shunning" of him and ban him from all its parks, reserves and recreational facilities.
At a meeting which was open to the public the council also reluctantly agreed to approve building and resource consents for a house on Whanganui Prison grounds where Wilson will live when he is released this week.
On Monday, the council lost a bid in the High Court at Wellington to prevent Wilson, dubbed the "Beast of Blenheim", from being paroled to the area.
Wilson served 18 years in jail for sex crimes, mainly against women and children.
Last night, the councillors approved five action points:
* To investigate the possibility of launching an appeal against Justice Ronald Young's High Court ruling.
* To undertake political lobbying to pass retrospective legislation.
* To form a group with the aim of launching a community safety plan.
* To co-ordinate a community shunning of Wilson.
* To ban Wilson from all council parks, reserves and recreational facilities.
Mayor Annette Main said the legal advice provided to the council indicated that there was no valid reason to withhold consent for the ex-state house in which Wilson will live at the prison grounds.
Councillors Michael Laws, Jack Bullock and Ray Stevens voted against the motion to approve the consents.
Councillors were unanimous in a decision to appeal against the High Court's decision, pending the release of Justice Young's full decision.
Mayor Main said the council had taken the opportunity to think about what to do next in the best interests of the Wanganui community.
"It is imperative we take a responsible and mature approach on behalf of our community and work alongside them, and relevant agencies, including the police and the Corrections Department."
