The families of two Swedish tourists murdered two decades ago, say they are not surprised that their killer could be freed from prison by November.
David Tamihere killed Heidi Paakkonen and Urban Hoglin in Coromandel in 1989.
A Parole Board report says Tamihere continues to deny his offending, but has made remarkable breakthroughs in his rehabilitation.
Ms Hoglin's brother, Stefan Hoglin, wants Tamihere to stay in prison for the rest of his life, but accepts that he must be released someday.
Mr Hoglin says both families still want to know why the killings happened and where Miss Paakkonen's body was buried.
He says they will make a joint approach to the Parole Board.
The Parole Board wants a residential restriction report prepared before it decides if Tamihere can be released in November.
