Police searched her property and turned up 821 cannabis plants inside the address. The summary did not give any detail on what stage of growth the plants were at.
Also located at the house were grow tents, lights, extractor fans and roof ducting - all of which are items that can be used in an indoor space to grow marijuana.
When spoken to by officers about their discovery, O’Sullivan admitted the cannabis was hers and said she grew it for personal use, the summary stated.
In court, she pleaded guilty to the charge.
Judge Gregory Hikaka ordered a pre-sentence report, stating the offending was of a concerning level and that O’Sullivan had set up “quite the operation”.
Police are seeking an order for the destruction of the items seized relating to the cultivation of the cannabis.
The matter was transferred to Taumarunui District Court for O’Sullivan’s sentencing on March 15.
