We use published data from the extensive \\emph{Near-Infrared Synoptic Survey} containing 3.5 million stars, of which 65,000 are red giants that fall within one magnitude of the TRGB. Adopting the TRGB slopes from a companion study of the isolated dwarf galaxy IC\\,1613 as well as an LMC distance modulus of \\(\\mu_0 = \\)~18.49~mag from (geometric) detached eclipsing binaries, we derive absolute \\(JHK\\) zero-points for the near-infrared TRGB.
