Despite his tender years, the Highlanders star is one of the most respected props in New Zealand rugby, has represented his country at every age-grade team and has also played for New Zealand Maori.
He made his Super 12 debut in 1999 and two years later he had the unique distinction of becoming the 1,000th All Black when he took to the field against Samoa in Albany.
Hayman toured Europe with the All Blacks on their end-of-year tour in 2002 before falling off the Test radar until 2004.
The industrious prop began his representative career with Otago under the wing of All Black props Carl Hoeft and Kees Meeuws.
