Measurements of the production rates of the D{sub 1}{sup 0}(2420) and D{sub 2}*{sup 0}(2460) mesons in hadronic Z{sup 0} decays are presented based on an analysis of over 4 million events recorded using the OPAL detector at LEP. These rates are determined separately for production in charm fragmentation and in the inclusive decays of bottom flavoured hadrons. The D{sub s1}{sup +}(2536) meson is also observed using its D*{sup 0}K{sup +} and D*{sup +}K{sub S}{sup 0} decay modes and an estimate of its production rate in charm fragmentation is presented. These are seen to be in agreement with recent phenomenological parametrizations of hadron production rates in Z{sup 0} decays.
