When he convicted and remanded Peck in custody for sentencing, at the time Justice Toogood warned him that preventive detention was a possibility. However, after receiving a psychological and psychiatrist's reports he ruled that out, instead opting for a lengthy jail term with an extended supervision order and minimum non-parole period.
Peck groomed the victim by firstly texting him on a daily basis and telling him that he loved him and that he was his boyfriend.
He also sent sexual text messages which were "provocative in nature".
Peck asked the victim to delete the messages because he would be "in big trouble" if the parents found out.
Most of the messages were one-sided but in some cases Peck would persist until he received one back or he rang the boy's parents.
The offending began with Peck watching the boy undress before it grew into making the boy watch pornographic movies and then sexual acts being performed.
Peck's lawyer Eric Forster painted a lonely life of Peck.
He had been single most of his life, was of "relatively modest academic means who thinks about things simply" and despite having earlier sexual offending convictions and jail terms, he had never received any treatment, he said.
"The temptation for him has been extremely difficult to manage because of his extreme loneliness."
Mr Forster said his client's offending was not the most serious of its kind, but Justice Toogood disagreed.
He also dismissed an apology letter - delivered yesterday - as "too little, too late".
Judge Toogood said the victim had been severely affected by the offending and he still suffered nightmares and was now "understandably angry" by what happened.
The judge also said Peck put the victim through added stress by taking it to trial.
Outside court, officer in charge of the case, Tauranga police Detective Helen Beck, said given the time span between the latest and previous offending she suspected Peck's offending might be more widespread and urged any other potential victims to come forward.
Peck's name suppression was finally lifted by Justice Toogood yesterday.
Peck lived in Whanganui for the first 30 years of his life before moving to Hawke's Bay in about 1999.
