Broad had since successfully completed the Salvation Army Bridge Programme, for those with drug and alcohol addictions, at a residential treatment centre in Wellington.
Mr Crowley said Broad was drug-free and committed to his rehabilitation.
Mr Crowley appealed for his client's sentence to be one of community work and supervision.
Crown prosecutor Joanna Woodcock acknowledged the steps Broad had taken to rehabilitate and that his offending was not akin to a commercial drug-manufacturing operation, so she did not oppose such a sentence.
Judge Cameron then gave his sentence indication, of community work and supervision, on which Broad admitted the three charges he faced: possession of equipment for the cultivation of cannabis, cultivating cannabis and producing cannabis oil, a Class-B drug.
Broad was convicted of those charges and sentenced to 150 hours' community work and six months' supervision, on the condition he undergo counselling or take part in treatment programmes as directed by his probation officer.
Judge Cameron also ordered the utensils Broad used in growing cannabis be destroyed.
