Year 13 student and Whangarei Boys' High School left wing David Nair said Bunceprovided timely advice on how to improve as a player game. He didn't really remember Bunce as a player but had heard that he had been amazing on the field.
Bunce has another engagement in Whangarei but that won't be until August 25 at a speaking engagement at Toll Stadium. In a TV chat show-style format, Bunce will share his most entertaining stories from his rugby career, his life after rugby and his thoughts on who will take home the Webb Ellis trophy with Sky commentator Scotty Stevenson.
