  Our knowledge of the populations and occurrence rates of planets orbiting
evolved intermediate-mass stars lags behind that for solar-type stars by at
least a decade. Some radial velocity surveys have targeted these low-luminosity
giant stars, providing some insights into the properties of their planetary
systems. Here we present the final data release of the Pan-Pacific Planet
Search, a 5-year radial velocity survey using the 3.9m Anglo-Australian
Telescope. We present 1293 precise radial velocity measurements for 129 stars,
and highlight six potential substellar-mass companions which require additional
observations to confirm. Correcting for the substantial incompleteness in the
sample, we estimate the occurrence rate of giant planets orbiting
low-luminosity giant stars to be approximately 7.8$^{+9.1}_{-3.3}$\%. This
result is consistent with the frequency of such planets found to orbit
main-sequence A-type stars, from which the PPPS stars have evolved.
