The $\kappa^{+}\rightarrow \pi^{+}\nu\bar\nu$, being very well predicted in the Standard Model, is one of the best golden modes to indirectly investigate the presence of new physics at highest mass scales. The NA62 experiment at CERN SPS is presently taking data for the third year, exploiting a decay-in-flight technique, with the goal to collect O(100) events for this ultra rare process (BR $\sim 10i - 10$). The statistics collected in 2016 allows NA62 to reach the SM sensitivity. The preliminary result based on this data set will be presented together with future prospects.
