He was one of four Hawke's Bay age group products, Ben Tameifuna, Dominic Bird and Brad Weber were the others, in the 2011 Baby Blacks team.
A nephew of Takapau-based former All Black prop John Ashworth, Retallick, who has been an All Black since 2012, won the 2014 World Player of the Year award. Retallick has been contracted to the Bay of Plenty union since 2012 but will leave that Bay without playing an ITM Cup game for the province and will again be affiliated to the Waipukurau-based Central club.
His wife Niki is from the Bay.
Central premier coach Exham Wichman said Retallick will be a huge boost for the club.
"We know we're unlikely to see him take the field for us but when he visits we can bounce ideas off him and the tips and experiences he can pass on the forwards will be great.
"He came to a few of our games last year and the way the boys responded to his tips was awesome.
"We made some good steps in the right direction this year by finishing sixth in the Maddison Trophy and getting players selected in the Hawke's Bay Saracens team.
"With Brodie's influence we can build on that. To have a bloke of that stature in our small community is massive ... the young JAB players will respond in a positive manner when they see him too," Wichman said.
"I remember when I was playing for Havelock North and the late Jarrod Cunningham used to turn up.
"The enthusiasm levels these sort of blokes bring to clubs ... you can't beat it," he added.
