He was campaign manager for the All Blacks for the 1995 World Cup, a selector from 2004-2007 and took on a range of other administrative and coaching roles within the game.
Yesterday's meeting in Wellington marked a double cause for celebration for Sir Brian, who was also voted in as the NZRU's patron, a position that had been vacant following the death of Sir Wilson Whineray last year.
"Well it's an honour really," Sir Brian said. "You don't expect these sort of things. For me I just set out to be an All Black, it was my ambition as a little fellow and I achieved that; I thought that was enough. But there's been a lot of add-ons since then in various situations in the game and I've enjoyed the whole lot of them and this is a great honour.
"And look, if I can do something for New Zealand rugby in my latter years, so be it, I'll try very hard."
The former lock and No8 said he enjoyed the opportunity to chat with current players but wouldn't actively seek a role with the All Blacks in any capacity.
"I'm a passionate All Black and I like very much to talk to the new All Blacks as long as they want to talk to me, I guess. I'll be happy to talk to them and if that happens, that's great but I won't be seeking that sort of thing."
The 72-year-old, who lives in Masterton, said his vision of being the NZRU's patron was about supporting the game at all levels. "I don't think I'll ever stop doing that," he said.
