Proisir (foaled 2009) is an Australian-bred Thoroughbred racehorse who won at Group 3 level at age 3 and has gone on to forge a successful career as a stud stallion in New Zealand.
Proisir's racing career included the following:
Proisir stands at the Rich Hill Stud in the Waikato, New Zealand. He started his career with a relatively low fee of NZ$7,000 and $9,000 in his initial years.
The service fee had risen to $17,500 by the 2023 season as a result of a number of Group race successes by his progeny.
In 2025 the Challenge Stakes at Hawkes Bay, which was previously called the Tarzino Trophy, became the Proisir Plate following sponsorship by Rich Hill stud.
