We study the precision measurement of the {ital WWZ}{sup 0} vertex in the process {ital e}{sup +}{ital e{minus}}{r arrow}{nu}{bar {nu}}{mu}{sup +}{mu}{sup {minus}} at a {radical}{ital s} =500 GeV {ital e}{sup +}{ital e{minus}} collider. We find that this process can be used to make a precise determination of the trilinear gauge boson couplings. Assuming an integrated luminosity of 2 fb{sup {minus}1}, in the reaction {ital e}{sup +}{ital e{minus}}{r arrow}{nu}{bar {nu}}{mu}{sup +}{mu}{sup {minus}}, {kappa}{sub {ital Z}} can be measured to 10% at the 95% C.L. and {lambda}{sub {ital Z}} to {plus minus}0.07 at 95% C.L. With the appropriate cuts on {ital M}{sub {mu}}{sup +}{mu}{sup {minus}}, {Delta}{kappa}{sub {ital Z}}={sub {minus}0.4}{sup +0.3} and {Delta}{lambda}{sub {ital Z}}={sub {minus}0.6}{sup +0.4} at 95% C.L. {ital independent} of deviations in {kappa}{sub {gamma}} and {lambda}{sub {gamma}}.
