"That's obviously a concern to him, [Wilson] as well as to the police who will have the ultimate responsibility to keep him safe."
Mr McKenzie said he had received several emails asking "what the hell" he was doing representing Wilson, but had not been threatened.
Among those to have spoken out against Wilson being released in Wanganui are the town's mayor Annette Main, former mayor Michael Laws and Maori Party co-leader Tariana Turia, who lives on the street he is due to be housed on.
Wilson will be subject to 17 parole conditions that strictly curtail where he can go and who he can associate with - conditions the Corrections Department say are the most stringent ever imposed.
Mr McKenzie said Wilson did not want to go to Wanganui, and was seeking to make an alternative arrangement.
"I think that in some ways could be seen as a bit of a recipe for disaster; forcing someone kicking and screaming to a community that doesn't want him."
Mr McKenzie would not say where Wilson would prefer to live.
"Wilson has rights; he has a right to be released and obviously there are a lot of things in place to ensure there is no reoffending.
"We also need to remember, of course, that most of his offending took place 20, 30 years ago. Now he's over 65 and circumstances are quite different."
