We have performed a series of neutron diffuse scattering measurements on asingle crystal of the solid solution Pb(Zn$_{1/3}$Nb$_{2/3}$)O$_3$ (PZN) dopedwith 8% PbTiO$_3$ (PT), a relaxor compound with a Curie temperature T$_C \sim450$ K, in an effort to study the change in local polar orders from the polarnanoregions (PNR) when the material enters the ferroelectric phase. The diffusescattering intensity increases monotonically upon cooling in zero field, whilethe rate of increase varies dramatically around different Bragg peaks. Theseresults can be explained by assuming that corresponding changes occur in theratio of the optic and acoustic components of the atomic displacements withinthe PNR. Cooling in the presence of a modest electric field $\vec{E}$ orientedalong the [111] direction alters the shape of diffuse scattering in reciprocalspace, but does not eliminate the scattering as would be expected in the caseof a classic ferroelectric material. This suggests that a field-inducedredistribution of the PNR has taken place
