She said the condition was not necessary because alcohol was not involved at the time of the alleged offending.
The men and a third defendant, Michael Alapati, face a charge of criminal nuisance endangering public safety and entering various residential and commercial buildings throughout the North Island.
Cox has also been charged with possessing a shotgun, explosives and cultivating cannabis.
Alapati is not due to appear in court until next month.
Police allege the men drove around Wellington, Rotorua, Hamilton, Tauranga and Auckland in a white Mitsubishi Delica van between January and July. It's claimed they wore high-visibility jackets while pretending to service the fire hydrants. Instead they allegedly removed the connections, which cost the taxpayer $1000 each to replace.
Police said the connections were sold to four different scrap-metal dealers for $10/kg.
Community magistrate Philip Greenbank removed the alcohol condition and minimised their curfew from 24 hours to 7pm to 7am.
The trio are due to appear in court on November 15.
