Nearly 100,000 have signed petition protesting sentence for drink driver who killed Auckland boy

A petition to appeal the sentencing of a driver who hit and killed a teenage boy has gathered nearly 100,000 signatures.

Fifteen-year-old Nathan Kraatskow died in May this year, after Rouxle Le Roux ran an amber light with her Mercedes while on Auckland's North Shore.

Le Roux, 19, had been drinking and smoking cannabis before the incident.

She was sentenced on Friday to 11 months home detention, which Nathan's mum says isn't enough for the damage she caused.

In court last week, Charlene Kraatskow pointed to an Instagram post from the defendant over Halloween in which she wore a prison jumpsuit and skeleton make-up with the caption: "hide your children".

"I just could not understand how someone could be so heartless and think this whole thing was a joke?" Charlene Kraatskow told the court.
