A mother facing drug driving charges over a crash that killed her 12-year-old daughter had methamphetamine in her system and was banned from driving just eight days earlier, police say.
Toni Maree Ericksen, 32, has pleaded not guilty to driving under the influence of drugs causing the death of her eldest daughter, Bryer, and will stand trial this year.
She also faces three related charges - injuring her 8-year-old daughter Gemma Greenwood and another motorist while under the influence of drugs, and being an unlicensed driver driving while prohibited.
Ericksen was driving her two daughters home from Gemma's netball game last July 9 when she lost control of her car on Kaipara Coast Highway and collided with an oncoming vehicle.
Her lawyer said she "vehemently denies" being affected by drugs.
