Charged alongside her is a 38-year-old man, who faced an identical count of possessing a glass pipe.
He was also charged with stealing nearly $500 of groceries - including meat, wine and dental-care products - in Christchurch from November 10 to 12.
The man will appear in court later today.
Senior Sergeant Anthony Bond said officers arrested the couple in Opoho outside Gardens New World about 2am yesterday.
The woman was in the car while the man was returning from a public toilet and numerous items of stolen property were found in their vehicle, Snr Sgt Bond said.
Further investigations were ongoing into other incidents in Canterbury and Otago, police confirmed.
