A man who was dubbed the 'Grey Lynn peeping tom' has been sentenced to three years and six months in prison for secretly recording women undressing, and couples having sex.

Father of three, Moana Tekawa, 48, was sentenced on Thursday at the Auckland District Court in front of Judge Anne Kiernan.

The court heard how Tekawa would prowl outside houses in the Auckland suburb and film women undressing, teenage girls in bed, and couples having sex.

Tekawa earlier admitted 14 charges related to making intimate visual recordings. He also admitted to 10 charges of burglary.

His offending occurred between November 2015 and May of last year, when he was arrested while peeping through a window on Sussex St.

Judge Kiernan outlined to the court the details of Tekawa's offending, which involved filming a range of people, often without their knowledge.

"Essentially you walked onto properties in the Grey Lynn area, often to the backs of those homes, and up to the windows of those properties in the evenings," she said.

"You took recordings on your phone of women, and some men, in various states of undress, or getting ready for bed, or people who were in bed."

"Usually the pictures you took were through the windows of bedrooms, bathrooms or dining rooms. Some of those recordings showed men and women engaging in sexual activity."

Keirnan said Tekawa would often put his arm through open windows or curtains to capture the images.

A laptop seized from Tekawa after his arrest had over 21,000 voyeuristic images of females undressing and engaging in sexual activity.

"The images have been put together to be watched like a video," Judge Kiernan said.

Victim impact statements read in part by Judge Kieran explained how one victim was scared to go outside at night after Tekawa was spotted looking through her window one evening.

"She talks about being very disturbed about what happened that night. She had to move address, and at times she worried about being out in the evening," Kiernan said.

Another victim in her 20s said it was the "most disturbing" experience she had ever had.

Judge Kieran noted a psychologist report made clear Tekawa suffered from serious mental health issues, however, this did not explain or justify his offending.

Tekawa stood motionless in the dock during sentencing and did not say anything when sentenced.
