We demonstrate that numerical relativity codes based on the it moving punctures formalism are capable of evolving nearly maximally spinning black hole binaries. We compare a new evolution of an equal-mass, aligned-spin binary with dimensionless spin chi=0.99 using puncture-based data with recent simulations of the SXS collaboration. We find that the overlap of our new waveform with the published results of the SXS collaboration is larger than 0.999. To generate our new waveform, we used the recently introduced \hispid puncture data, the CCZ4 evolution system, and a modified lapse condition that helps keep the horizon radii reasonably large.
