The woman charged after allegedly ramming a police car in downtown Auckland and committing more offences on bail is in an acute mental health unit.
Community Magistrate Jan Holmes was told the woman, 60, would need treatment for a while because she was still acutely unwell.
Auckland District Court also heard two nurses would need to accompany the 60-year-old from the Auckland facility to Northland, where she will continue receiving treatment.
Court documents showed she faced charges including assault with a blunt instrument, failing to stop and injuring with intent to cause grievous bodily harm, which carries a maximum 10-year jail term.
She was also accused of dangerous driving, driving contrary to a zero alcohol licence, and wilful trespass.
