We investigate localization of the entanglement of multimode Gaussian states into a pair of modes by local Gaussian measurements on the remaining modes and classical communication. We find that for pure states and for mixed symmetric states maximum entanglement between two modes can be localized by local homodyne detection - i.e. projections onto infinitely squeezed states. We also show that non-Gaussian measurements allow us to localize more entanglement than Gaussian ones.
