Five people who are jointly charged with growing cannabis have now been charged with also stealing nearly $100,000 worth of electricity.

The men, aged between 24 and 67, were charged with cultivating cannabis last month, but have now been charged with stealing $99,268.96 worth of electricity from Genesis Energy, according to court documents seen by Stuff.

A police spokesperson confirmed the investigation ended in August and the five men are now set to appear in the Manukau District Court.

Another person has been referred to Youth Aid.

A Genesis Energy spokeswoman said it assisted police with their inquiries.
