We present results from the third portion of the Methanol Multibeam Galactic plane survey of masers at 6668 MHz. It covers the longitude range 330°–345°, yielding 198 masers, of which more than 40 per cent are new discoveries. The maser population in this longitude range is the densest anywhere in the Galaxy, with many sources delineating a large portion of the Norma spiral arm close to its tangent point, and a cluster defining the southern tangent point of the 3-kpc ring. Two sources lie outside the solar circle, on the far side of the Galaxy, more than 15 kpc away.
