We searched for ultrahigh-energy rays emitted by the supernova 1987A with a new cosmic-ray facility installed at the Black Birch Range in New Zealand. The observations from 13 October to 3 December 1987 suggest no clear clustering of events around the direction of the supernova. We conclude that an upper limit on the flux rays of energies greater than 100 TeV is 1.1×10-12 cm-2 s-1 (95% confidence limit) for a differential spectral index =2.0 and source distance d=50 kpc. This value gives an upper bound on the -ray luminosity of the supernova of 5.5×1038 erg s-1 for 1014, 1017 eV.
