Measurements of the branching fractions of B0d,s→K*±h∓ (h = π,K) decays are performed, using pp collision data at the LHCb experiment. The data sample corresponds to an integrated luminosity of 1:0 fb-1, collected at a centre-of-mass energy of 7TeV. First observation of the B0s→K*±K∓ and evidence for the B0s→K*-π+ decay modes are reported. The following branching fraction measurements and limits of the B0d,s→K*±h∓ (h = π,K) decay modes, relative to the well measured B0→K*+π- decay, are obtained B (B0s→K*±K∓) / B (B0→K*+π-) = 1.49 ± 0.22 (stat.) ± 0.18 (syst.) B (B0→K*±K∓) / B (B0→K*+π-) < 0.06 at 95% CL. B (B0s→K*-π+) / B (B0→K*+π-) = 0.39 ± 0.13 (stat.) ± 0.05 (syst.)
