A young Hawke's Bay mother who had meth in her system when she crashed her car, killing her 2-year-old daughter, has been sentenced to home detention.

Valencia Skipper, who was 21 at the time of the crash and not licensed to drive, was earlier sentenced to prison but this was overturned.

The Court of Appeal quashed the two-and-a-half year jail term last month, after her lawyer successfully argued the sentence was too harsh.

Skipper was re-sentenced on Thursday at the Napier District Court to four months' home detention.

She has also been disqualified from holding a driver's licence for three years.

Skipper was found guilty by a judge of causing the death of her toddler, Saphire Skipper-Hira, in a crash on the Hawke's Bay Expressway last January.

She had a very low level of methamphetamine in her system at the time of the crash.
