The New Zealand professional heavyweight boxer Shane Cameron has been heavily supported with the TAB to beat compatriot David Tua in their June bout.
One punter has invested $10,000 on Cameron at $2.50 to win the fight and his price has been cut to $2.25.
Tua, inactive for about 18 months, has been largely neglected in the betting and his price is now $1.60.
The Cameron - Tua book has been open for less than week but the TAB's Mark Stafford says the interest has been staggering for an event which is still over four months away.
