Last June, Orchiston had admitted multiple charges of sexual offending against girls under 12.
The offences included indecently assaulting a female under 12, unlawful sexual connection with a female under 12, and doing an indecent act on children under 12
The offences, which included crimes described by Orchiston as "a funny sort of thing that happens", were committed in 2018 and involved three victims.
Orchiston was once a respected Hawke's Bay winemaker, as well as a travelling sweet salesman.
But he was jailed in 2003 after a trial, in which he was found guilty of similar offences against young girls. He was released in 2008 after serving a 4-1/2 year sentence.
Last June, in the Hastings District Court, head bowed, Orchiston admitted he had offended again - he pleaded guilty to 23 offences that happened in 2018 - a decade after his prison release.
A police summary of facts outlined his modus operandi - he befriended all three victims and their families, quickly gaining their trust.
He treated the children to outings at McDonald's and gave them money, gifts and clothing.
He took the girls away on trips, where he tried to get them to go "skinny dipping" with him. They declined.
Orchiston would also touch the girls inappropriately. He was charged after children's clothing including underwear, swimming togs and erotic publications were found when they searched his Flaxmere home in May.
