A search of Nixon's home found other items related to the manufacture of cannabis oil and chopped cannabis leaf material fried in butter in the fridge.
Nixon's counsel, Stephen Ross, said she had no criminal history and was willing to undertake rehabilitation programmes.
A pre-sentence report on Nixon revealed she worked as a chef and that she had a harmful background of drug use.
Judge Cameron said it was an aggravating factor that she had offended across a wide spectrum in the sense she had grown the cannabis, produced the oil, and supplied it to others. He saw a degree of sophistication and preparation in her dispatch of the drugs to the South Island.
The judge sentenced her to three months' home detention, with six months' post-release conditions.
