The country's longest-serving prisoner will not get a chance at freedom for another three years.
In 1968, Alfred Thomas Vincent was convicted on seven convictions of indecent assault on five boys aged between 12 and 14.
By then he had six prior convictions from three separate court cases over indecent assault against young boys. He was the first person in the country to be sentenced to preventive detention.
The recidivist paedophile first became eligible for parole 40 years ago.
This is Alfred Vincent's 48th year behind bars.
The Parole Board considered a five year postponement order but in a decision released this afternoon says it was too long because he'll be 78 later on October 22.
In jail, Vincent claimed he had assaulted as many as 500 boys in Canterbury between the 50s and 70s, however that number hasn't been verified.
Vincent was declined parole in August this year with the Board saying despite his age, he remains an undue risk to the community.
"He is highly institutionalised and there are no regenerative activities or agencies able to provide the intense level of surveillance and management that would be needed if he were to be released." the Board says.
Vincent will next be considered for parole in 2018.
Auckland human right's lawyer Tony Ellis is considering taking his case to the United Nations.
