We present the results of a perturbative calculation to match the axial andvector currents for semileptonic $B\to D^{(\ast)}$ decays in lattice NRQCD tothe continuum \MSb scheme. The matching is performed to$O(\alpha_s\frac{\vec{p}}{M})$ in Feynman gauge and in the on-shellrenormalisation scheme.  The spatial and temporal components of the currents renormalise differently;to this order the matching involves a straightforward renormalisation for the$V_0$ and $A_k$ currents, and a rank two and four mixing matrix for the $A_0$and $V_k$ currents respectively. The resultant one loop corrections are of$O(5%)$, boding well for the accuracy of forthcoming simulations.Comment: 24 Pages, 18 Figure
