Most of the new physics models providing an explanation to massive neutrinos imply the existence of Neutrino Non Standard Interactions (NSIs). These interactions can lead to potentially observable, sub-dominant effects in the oscillation patterns of neutrinos propagating through the Earth’s matter. KM3NeT is a next-generation neutrino telescope currently under construction in the Mediterranean Sea. KM3NeT/ORCA is a dense array that constitutes the low-energy branch of KM3NeT with the main aim of determining the neutrino mass ordering. The KM3NeT neutrino telescope has already gathered the first data and proven its capability for measuring atmospheric neutrino oscillations with the KM3NeT/ORCA Phase1 detector. The first stage of the KM3NeT/ORCA detector operating with 6 detection units, also called ORCA6, was collecting data for almost two years until it was extended with additional lines. This contribution presents the first attempt to measure Neutrino Non-Standard Interactions with the data gathered by the ORCA6 detector. The data taking period spans over more than one year from January 2020 until March 2021. The limits of the similar order of magnitude to the current world-leading measurements are reported providing very promising prospects for the future beyond standard model searches with the KM3NeT/ORCA detector. The reliability of the obtained results is tested thoroughly using various statistical methods and verifying the assumptions commonly made in the explored field of research.
