  A measurement of the cross-section for pp->Z->e+e- is presented using data at
sqrt{s}=7TeV corresponding to an integrated luminosity of 0.94 fb^{-1}. The
process is measured within the kinematic acceptance pT>20GeV/c and 2<\eta<4.5
for the daughter electrons and dielectron invariant mass in the range
60--120GeV/c^2. The cross-section is determined to be
\sigma(pp->Z->e+e-)=76.0+-0.8+-2.0+-2.6pb where the first uncertainty is
statistical, the second is systematic and the third is the uncertainty in the
luminosity. The measurement is performed as a function of Z rapidity and as a
function of an angular variable which is closely related to the Z transverse
momentum. The results are compared with previous LHCb measurements and with
theoretical predictions from QCD.
