OH megamasers (OHMs) are rare, luminous galaxies that produce masing lines predominantly at 18cm. When redshifted, these lines can "contaminate" untargeted 21cm neutral Hydrogen (HI) surveys if the optical spectroscopic redshift of the object is unknown. While this may be uncommon at at low redshifts (z<~0.1), this becomes a much more prevalent issue at higher redshifts where OHMs are likely to be more more common since they are products of major galaxy mergers. We are also on the cusp of a new era of HI surveys as many Square Kilometre Array (SKA) precursors come online which will reach sensitivities and redshifts that had never previously been obtainable. We propose to obtain spectroscopic redshifts for 10 ambiguous HI or OH sources identified in brand new data obtained with the MeerKAT Array, an SKA precursor. These would be some of the first OHMs identified using SKA precursors and would greatly impact future suveys on these next-generation arrays.
