The spin-web compound Cu₃TeO₆, belongs to an intriguing group of materials where magnetism is governed by 3d⁹ copper Cu²⁺ ions. This compound has been sparsely experimentally studied and we here present the first investigation of its local magnetic properties using muon-spin relaxation/rotation(μ⁺SR). Our results show a clear long-range 3D magnetic order below T_N as indicated by clear zero-field (ZF) muon-precessions. At T_N = 61.7 K a very sharp transition is observed in the weak transverse-field (wTF) as well as ZF data. Contrary to suggestions by susceptibility measurements and inelastic neutron scattering, we find no evidence for either static or dynamic (on the time-scale of μ⁺SR) spin-correlations above T_N.
