We present deep optical and near-infrared photometry of UID 30901, asuperluminous supernova (SLSN) discovered during the UltraVISTA survey. Theobservations were obtained with VIRCAM ($YJHK_{s}$) mounted on the VISTAtelescope, DECam ($griz$) on the Blanco telescope, and SUBARU Hyper Suprime-Cam(HSC; $grizy$). These multi-band observations comprise +700 days making UID30901 one of the best photometrically followed SLSNe to date. The host galaxyof UID 30901 is detected in a deep HST F814W image with an AB magnitude of$27.3 \pm 0.2$. While no spectra exist for the SN or its host galaxy, weperform our analysis assuming $z = 0.37$, based on the photometric redshift ofa possible host galaxy found at a projected distance of 7 kpc. Fitting ablackbody to the observations, the radius, temperature, and bolometric lightcurve are computed. We find a maximum bolometric luminosity of $5.4 \pm 0.34\times 10^{43}$ erg s$^{-1}$. A flattening in the light curve beyond 600 daysis observed and several possible causes are discussed. We find the observationsto clearly favour a SLSN type I, and plausible power sources such as theradioactive decay of $^{56}$Ni and the spin-down of a magnetar are compared tothe data. We find that the magnetar model yields a good fit to the observationswith the following parameters: a magnetic field $B = 1.4 \pm 0.3 \times 10^{14}\ G$, spin period of $P = 6.0 \pm 0.1 \ ms$ and ejecta mass $M_{ej} =11.9^{+4.8}_{-6.4} M_{\odot}$.
