A scaffolder involved in Christchurch's rebuild was busted for cultivating cannabis after he was picked up on an outstanding warrant in raids yesterday.
Police conducted a city-wide operation targeting about 150 offenders on outstanding warrants.
As of this afternoon police had arrested 34 offenders and Superintendent Gary Knowles said he was "confident" the remainder would be caught.
Of those arrested 29 were male, five female.
All appeared at the district court today.
