goal of finding more gas giant planets orbiting super metal-rich stars to increase the statistics, whilst also following up any discoveries to search for transit events. The first results from this work and the target sample were discussed in @jenkins09 and since then our program has expanded to make use of the CORALIE spectrograph [@jenkins11a; @jenkins11b; @jenkins13b]. This current paper announces the first planets from this survey detected using CORALIE and goes on to study the planet mass-metallicity plane to search for correlations between these two parameters.

In this work we describe the latest efforts from our Calan-Hertfordshire Extrasolar Planet Search, which builds on previous work by this group. We include the new giant planets we have detected in this program with the large sample of gas giants detected by radial velocity measurements that already exist in the literature, in order to continue the search for emerging correlations that allow us a more stringent insight into the nature of these objects. In $\S~\ref{observations}$ we describe the measurements used in this work. In $\S~\ref{star}$ we discuss the sample selection, introduce the new giant planet detections from this survey, and discuss some characteristics of their host stars. In $\S~\ref{results}$ we perform tests
