An Auckland woman who was sentenced to home detention after killing a 15-year-old cyclist in a hit-and-run appears to have made light of the situation in several Instagram posts.

In May, Rouxle Le Roux, 19, hit Nathan Kraatskow with her car at the intersection of Oteha Valley Rd and the northern motorway on ramp in Albany.

Mr Kraatskow died as a result and Le Roux was charged with dangerous driving causing death.

On Friday she was sentenced to 11 months home detention and 250 hours community service.

But months earlier Le Roux appeared to make light of her charges, posting images on Instagram of herself sitting at a bus stop.

"Only thing I'll be catching," she wrote with the hashtag "Canthurtemifigotnone" - apparently referring to no longer being allowed to drive.
