A West Auckland woman pleaded guilty to poisoning her elderly mother. She also pleaded guilty to arson.
On June 28 at 8:30am, the 51-year-old mixed Round Up weedkiller into tea. She brought it to her 83-year-old mother's bedside.
The mother drank one sip before noticing an odd smell and taste. Glyphosate, the active chemical in the herbicide, was later found in her system.
But the single sip caused no serious injury. Later that morning, after a verbal altercation, the woman set three fires.
She used matches, paper and accelerant. One caused moderate damage to the lounge.
She told police she wanted her mother "out of her life". She called the burning an "act of revenge".
The woman has schizophrenia. She has been on medication for 20 years.
She remains in custody pending sentencing in February.
