Police discovered more than the stolen caravan they were looking for when they went to a secluded residential property inland from Taipa.
They found the caravan, which had been reported stolen from Parapara, but also discovered that it contained chemicals believed to be those used in the manufacture of methamphetamine, when they visited the property on Tuesday.
The plan to tow the caravan to the Mangonui police station was abandoned.
Members of the Auckland clan lab team arrived yesterday morning to conduct an expert examination.
No confirmed details of the caravan's contents were available yesterday afternoon, but a 40-year woman, who is believed to live at the address, was charged with possessing and selling cannabis, cultivating the drug and receiving the caravan.
