He said he was in Rotorua for only a short time and had stopped here because of the interest shown by coaches and because of the strong Maori culture.

Rotorua Boxing Club co-director Lee Edmonds said he had learned from Mr Mendenhall's philosophy.
"He said when it comes to recruiting he does not ask potential players what they can do but if they will do it."
During his 10-day trip Mr Mendenhall has toured around the North Island speaking at marae and high schools and meeting families his father and grandfather knew. He was to return to the US today.
