Former Olympic Games silver medalist and manager of David Tua, Kevin Barry is to take over the training of top New Zealand heavyweight boxing prospect Joseph Parker.

Parker is due to fly to Las Vegas on April 14 to prepare for his fight against Francois Botha there.

Parker will live in Las Vegas with Barry and his family while Barry, the light-heavyweight silver medalist in Los Angeles in 1984, will arrange top professionals to spar with Parker to ensure he is in his best fighting shape for the June 13 contest to be fought over eight three-minute rounds.

On Barry's books at the moment is world light heavyweight champion Beibut Shumenov of Kazakhstan. He managed Tua from 1992-2003, training him for the last three years of that time.

Parker's previous trainer was Lee Parore.
