Otago University marketing associate professor Robert Aitken said earlier today that if the brewing giant had chosen Armstrong for one of its campaigns, it was an interesting choice.
"It might be a new career for him as an inspirational or motivational speaker but it is a very strange move," Aitken said.
"But they're very calculated, alcohol companies, and they must see some value - there has to be a genuine belief that he can bring something to the brand that isn't already there."
Aitken said it was likely to be a left-field campaign or targeting athletes or lower-alcohol drinkers, saying Armstrong was already creating a media stir in the country.
