He was sentenced in the Whanganui District Court on July 21.
In court, defence lawyer Megan Jaquiery said her client maintained his actions towards the victim were not sexually motivated, but he had entered guilty pleas because he didn't want to make them give evidence.
He was of good character and he had done "a number of good things in his community", Jaquiery said.
Crown prosecutor Ryan Benic said the man had committed prolonged, serious offending, and although he had offered to assist police when confronted with evidence, he "didn't identify any other offences or offenders".
Judge Ian Carter said it was troubling the man continued to deny sexual conduct with a child.
"That denial is indicative of a lack of remorse," Carter said.
His only previous conviction had been for reckless driving a number of years ago.
He was sentenced to two years and 10 months' imprisonment.
He will now be on the sex offender register.
The electronic devices that were seized have been ordered to be destroyed.
