Watch: Rugby: All Blacks arrive in USA
"But the majority of the money is going on the 57.5 points start for the All Blacks - effectively, they're betting that the All Blacks will thrash the USA Eagles by 58 points or more, paying $1.87."
Mr Saville said what was particularly interesting was where bets would go once the starting squads were announced this week.
"Although we can't open a book on it, we're predicting the return of Sonny Bill Williams straight into the starting side - but we're less sure of how many tries he'll score.
"We'll be letting punters decide with a special book on SBW's try-scoring abilities for this match."
Former All Blacks Eric Rush and Michael Jones are understood to be taking part in events leading up to the match, and Indycar driver Scott Dixon and American actress Jessica Pimentel are among celebrities attending the game. Kiwi opera sensation Sol3 Mio will sing the New Zealand national anthem, joining local opera singer Jim Cornelison, who will perform The Star-Spangled Banner.
