  We reconstruct the underlying density field of the 2 degree Field Galaxy
Redshift Survey (2dFGRS) for the redshift range 0.035<z<0.200 using the Wiener
Filtering method. The Wiener Filter suppresses shot noise and accounts for
selection and incompleteness effects. The method relies on prior knowledge of
the 2dF power spectrum of fluctuations and the combination of matter density
and bias parameters however the results are only slightly affected by changes
to these parameters. We present maps of the density field in two different
resolutions: 5 Mpc/h and 10 Mpc/h. We identify all major superclusters and
voids in the survey. In particular, we find two large superclusters and two
large local voids. A version of this paper with full set of colour maps can be
