  We report a new giant planet orbiting the K giant HD 155233, as well as four
stellar-mass companions from the Pan-Pacific Planet Search, a southern
hemisphere radial velocity survey for planets orbiting nearby giants and
subgiants. We also present updated velocities and a refined orbit for HD 47205b
(7 CMa b), the first planet discovered by this survey. HD 155233b has a period
of 885$\pm$63 days, eccentricity e=0.03$\pm$0.20, and m sin i=2.0$\pm$0.5
M_jup. The stellar-mass companions range in m sin i from 0.066 M_sun to 0.33
M_sun. Whilst HD 104358B falls slightly below the traditional 0.08 M_sun
hydrogen-burning mass limit, and is hence a brown dwarf candidate, we estimate
only a 50% a priori probability of a truly substellar mass.
