Eligibililty is restricted to yearlings sold at auction at only those sales at which the Auctioneers have been duly appointed by the NZ Sires' Stakes Board to receive entries. Any yearling nomination is accepted on the understanding that the horse concerned has not been broken into harness, hopples and/or gaited at the time of sale. The owner of each yearling must complete an entry declaration prior to that yearling being offered for sale stating that it has not been broken in as aforementioned.
