We calculate 2-point correlators for New Massive Gravity at the chiral point and find that they behave precisely as those of a logarithmic conformal field theory, which is characterized in addition to the central charges c(L) =c(R) = 0 by 'new anomalies' b(L) =b(R) = -sigma 12l/G(N) where sigma is the sign of the Einstein-Hilbert term, l the AdS radius and G(N) Newton's constant.
