We report the results of our spectropolarimetric monitoring of the weak-lineT-Tauri stars (wTTSs) Par 1379 and Par 2244, within the MaTYSSE (MagneticTopologies of Young Stars and the Survival of close-in giant Exoplanets)programme. Both stars are of a similar mass (1.6 and 1.8 M$_{\odot}$) and age(1.8 and 1.1 Myr), with Par 1379 hosting an evolved low-mass dustycircumstellar disc, and with Par 2244 showing evidence of a young debris disc.We detect profile distortions and Zeeman signatures in the unpolarized andcircularly polarized lines for each star, and have modelled their rotationalmodulation using tomographic imaging, yielding brightness and magnetic maps. Wefind that Par 1379 harbours a weak (250 G), mostly poloidal field tilted$65^{\circ}$ from the rotation axis. In contrast, Par 2244 hosts a strongerfield (860 G) split 3:2 between poloidal and toroidal components, with most ofthe energy in higher order modes, and with the poloidal component tilted$45^{\circ}$ from the rotation axis. Compared to the lower mass wTTSs, V819 Tauand V830 Tau, Par 2244 has a similar field strength, but is much more complex,whereas the much less complex field of Par 1379 is also much weaker than anyother mapped wTTS. We find moderate surface differential rotation of$1.4\times$ and $1.8\times$ smaller than Solar, for Par 1379 and Par 2244,respectively. Using our tomographic maps to predict the activity related radialvelocity (RV) jitter, and filter it from the RV curves, we find RV residualswith dispersions of 0.017 kms$^{-1}$ and 0.086 kms$^{-1}$ for Par 1379 and Par2244, respectively. We find no evidence for close-in giant planets aroundeither star, with $3\sigma$ upper limits of 0.56 and 3.54 M$_{\text{jup}}$ (atan orbital distance of 0.1 au).
