Type Ia supernovae (SNe Ia) are excellent standardizable candles that are routinely used to obtain ~7% extragalactic distance estimates. Improved standardization techniques have now showed how these can be even further improved, approaching the limit where SNe Ia are truly "standard". Simultaneously, a new generation of wide-field surveys will repeatedly observe the full observable nearby universe. The Zwicky Transient Facility (ZTF) pioneers this development and could provide high quality lightcurves of thousands of nearby SNe each year. I will introduce how SNIa distances are derived, describe ZTF and discuss how SNIa peculiar velocities could be used to derive an unbiased measurement of matter clustering in the z<0.1
Universe.
