Abstract
The null quasi-spherical gauge is being used to implement the numerical solution of the full Einstein equations, without any symmetry assumptions. This report describes the structure of the Einstein equations in the NQS gauge, and then outlines the numerical algorithm and specialised techniques being employed. Some preliminary results showing the decay of the Bondi mass of the spacetime are presented.
{\it Keywords:} Einstein equations, quasi-spherical, null characteristic hypersurfaces, eth, spin-weighted spherical harmonics.
