In this work, we consider the London limit of the (2+1)D Georgi-Glashow model with dynamical quarks. Following Polyakov's monopole plasma approach and using dual methods to treat the relevant matter sector, we derive in a clear and straightforward manner the recently proposed gauging of the discrete Z(N) symmetry of the associated effective vortex theory. Our procedure applies to bosonic as well as to fermionic matter, enabling to derive a useful representation for the Wilson loop and discuss string breaking, due to the creation of dynamical quark-antiquark pairs. This phenomenon corresponds to a perimeter law, a behavior that has been already observed in the lattice.
