The VVV NIR Survey had performed time-domain observations in the Ks-band for 6 years and provides an atlas of 562 sq. deg. of the sky in 5 wavebands (ZYJHKs). The VVV data products offer a unique dataset to map the stellar populations deeply embedded on highly obscured regions. The recent discoveries and characterization of a significant number of globular clusters (GCs) distributed in different regions of our Galaxy, using the VVV data, evidence the incompleteness of the known GC population. The new discoveries are importrant and impact statistically on the global known propreties of these objects. In this talk I will discuss the different and indirect methods used to discover new and low luminosity globular clusters in the most obscured regions of our Galaxy, and the requirements or tests to take into account to confim their real GC nature.
