  We present the results of our spatially resolved investigation into the
interplay between the ages of the stellar populations and the kinematics of the
warm ionised outflows in the well-studied type II quasar Markarian 34.
Utilising IFS data, we determine the spatial distribution of the young stellar
population (YSP; $t_{ysp} < 100 \mbox{ Myr}$) using spectral synthesis
modelling. We also employ the $\mbox{[OIII]}\lambda 5007$ emission line as a
tracer of the warm ionised gas kinematics. We demonstrate a spatial correlation
between the outer edges of the blue-side of the outflow and an enhancement in
the proportion of the YSP flux, suggesting that the outflow is responsible for
triggering star formation in this region. In regions with more highly disrupted
gas kinematics, we find that the proportion of YSP flux is consistent with that
found outside the outflow region, suggesting that the increased disruption is
preventing a similar enhancement in star formation from occurring. Our analysis
suggests that Mrk 34 is an example of quasar driven outflows simultaneously
producing both `positive' and `preventive' feedback, further demonstrating the
complex nature of the relationship between quasars and their host galaxies.
