And one Kiwi punter stands to walk away with a cool $72,000 if the Black Caps beat hosts England, after placing a six-to-one bet before the semifinals.
Another punter put down $2000 on New Zealand glory when the odds were eight to one.
Bets came flooding in after New Zealand's shock semifinal win over India.
On Thursday, about 5000 people had backed the Black Caps to win the World Cup final, and although those numbers had not changed substantially by Saturday, Stafford said he expected bets to ramp up today.
"People tend to wait to see what the weather is going to do. At this stage, it looks like there could be a few showers in the middle of the match but it doesn't look like they'll be needing to leave the field.
"We expect bets to pick up through the day, and especially with it now free-to-air on Prime. When people can watch, they are more likely to bet on it."
People making game day bets also tended to back the underdogs and often in smaller amounts of $10 and $20, Stafford said.
For New Zealand and England, a victory tonight would be the first time either had lifted the World Cup.
According to the TAB, though, England are firm favourites paying out $1.30, and the Black Caps are on $3.35.
