  The rate and corresponding gluon jet energy distribution for the process
$e^+e^- \to t\bar tg$ are sensitive to the presence of anomalous dipole-like
couplings of the top to the photon and $Z$ at the production vertex. For
sizeable anomalous couplings of this type substantial deviations from the
expectations of the Standard Model are likely. We explore the capability of the
NLC to discover or place bounds on these types of top quark couplings. The
resulting constraints are found to be quite complementary to those which arise
from direct probes of the top quark production vertex. [To appear in {\it
