We present the first detailed integral field spectroscopy study of ninecentral void galaxies with M*>10^10 Msun using the Wide Field Spectrograph(WiFeS) to determine how a range of assembly histories manifest themselves inthe current day Universe. While the majority of these galaxies are evolvingsecularly, we find a range of morphologies, merger histories and stellarpopulation distributions, though similarly low Halpha-derived star formationrates (<1 Msun/yr). Two of our nine galaxies host AGNs, and two have kinematicdisruptions to their gas that are not seen in their stellar component. Mostmassive void galaxies are red and discy, which we attribute to a lack of majormergers. Some have disturbed morphologies and may be in the process of evolvingto early-type thanks to ongoing minor mergers at present times, likely fed bytendrils leading off filaments. The diversity in our small galaxy sample,despite being of similar mass and environment means that these galaxies arestill assembling at present day, with minor mergers playing an important rolein their evolution.  We compare our sample to a mass and magnitude-matched sample of fieldgalaxies, using data from the Sydney-AAO Multi-object Integral fieldspectrograph (SAMI) galaxy survey. We find that despite environmentaldifferences, galaxies of mass M*>10^10 Msun have similarly low star formationrates (<3 Msun/yr). The lack of distinction between the star formation rates ofthe void and field environments points to quenching of massive galaxies being alargely mass-related effect.
