Dusty, neutral outflows and inflows are a common feature of nearbystar-forming galaxies. We characterize these flows in eight galaxies -- mostlyAGN -- selected for their widespread NaI D signatures from the Siding SpringSouthern Seyfert Spectroscopic Snapshot Survey (S7). This survey employs deep,wide field-of-view integral field spectroscopy at moderate spectral resolution(R=7000 at NaI D). We significantly expand the sample of sightlines in externalgalaxies in which the spatially-resolved relationship has been studied betweencool, neutral gas properties -- N(NaI), Weq(NaI D) -- and dust -- E(B-V) fromboth stars and gas. Our sample shows strong, significant correlations of totalWeq with E(B-V)_stars and g-i colour within individual galaxies; correlationswith E(B-V)_gas are present but weaker. Regressions yield slope variations fromgalaxy to galaxy and intrinsic scatter ~1 Angstrom. The sample occupies regionsin the space of N(NaI) and Weq^abs vs. E(B-V)_gas that are consistent withextrapolations from other studies to higher colour excess [E(B-V)_gas ~ 1]. Forperhaps the first time in external galaxies, we detect inverse P Cygni profilesin the NaI D line, presumably due to inflowing gas. Via Doppler shifted NaI Dabsorption and emission lines, we find ubiquitous flows that differ fromstellar rotation by >100 km/s or have |v,abs - v,em| > 100 km/s. Inflows andoutflows extend toward the edge of the detected stellar disk/FOV, togethersubtend 10-40% of the projected disk, and have similar mean N(NaI) and Weq(NaID). Outflows are consistent with minor-axis or jet-driven flows, while inflowstend toward the projected major axis. The inflows may result fromnon-axisymmetric potentials, tidal motions, or halo infall.
