A registered nurse who had sexual liaisons with three teenage boys has been sentenced to a year's home detention.

Aroha Veronica Webber, 41, was sentenced in the Rotorua District Court today after earlier pleading guilty to six charges of unlawful sexual connection with the 15-year-olds.

Her counsel, Paul Mabey, QC, submitted if they had been a year older no carnal crime would have been committed. She had not sexually groomed the boys.

He outlined how they had gathered at Webber's home when she was in a fragile state following her marriage breakdown. As a result of this she had "hit the booze" and the offending had occurred, Mr Mabey said.

She had allowed the boys into her home rather than see them wandering the streets.

Webber strenuously denied a claim in a victim impact statement that one of the boys had contracted a sexually transmitted disease from her.

"She is a registered nurse, she knows her own body's health," Mr Mabey submitted.

Judge James Weir also discounted the allegation. He noted her offending had been entirely out of character and had occurred when she was "disinhibited" by alcohol.
