Three Taranaki men have today been sentenced to Home Detention in the High Court at New Plymouth, for the manslaughter of Christine Fairweather.

21-year-old Daniel Gavin has a seven-month home detention sentence, while 19-year-old Samuel Hawkins got nine months, and 18-year-old Jayson Campbell will be monitored for 12 months.

All three have also been ordered to complete 100 hours of community service.

57-year-old Christine Fairweather died after she was hit by a car as she tried to remove four gates from a busy South Taranaki road.

The three offenders had put them there, as part of a prank.

Mrs Fairweather's husband and sister both fought back tears as they read their victim impact statements, pointing out the lack of remorse on the part of both Campbell and Hawkins.

Her sister Dianne Coleman said the family's been disappointed neither Campbell nor Hawkins showed any remorse.

"I was pleased that Daniel Gavin got less of a sentence because he's really the only one of the three that showed any sort of remorse and is actually doing something to change his life".

Justice Matthew Muir said they'd all been influenced by peer pressure, but that didn't detract from what their actions were.

"Rank stupidity without so much as a glimmer of intelligent forethought as to the consequences of your actions".

Geoff Hart who was driving the car which hit Mrs Fairweather has already pleaded guilty to careless driving causing death, and been sentenced to 100 hours community service.
