  We associate 132 low-mass ultracool dwarfs in the southern hemisphere as
candidate members of five moving groups using photometric and astrometric
selection techniques. Of these objects, we present high resolution spectroscopy
for seven candidates and combine these with previous measurements from the
literature to determine spectral types and radial velocities. We thus constrain
distance and space motion spectroscopically, allowing the kinematic membership
of the moving groups to be assessed. Possible membership of moving groups has
allowed ages and metallicities to be constrained for these objects and
evolutionary models have been used to estimate their mass. We estimate that up
to ~75 of our candidate moving group members should be genuine, and discuss
future work that will confirm and exploit this major new sample.
