A stallion must be registered annually for his foals to be eligible for entry in the Stud Book. The fee for this is $75.00.

The stallion manager is responsible for lodging a Certificate of Service every season. This form lists the mares covered during the season, and the first and last dates of service. The fee for this varies according to the number of mares covered. Once again, this can be done online or over the phone.

Under Stud Book regulations, a foal must be conceived by natural service. Artificial insemination and embryo transplant are prohibited. See Rule 407 of the NZ Rules of Racing.

The covering season begins on 1 September each year.
