TAB sports bookmaker Kieran McAnulty said it equals the biggest ever sports payout.
Another punter won $250,000 in 2007, but his sports multi outlay of $88,000 massively outweighed last night's winning bet, which meant this week's punter cleared $245,000.
"I get quite nervous when I have a $10 bet on a game, so I can't imagine what he was going through. Good on him,'' said Mr McAnulty.
Vanessa Manihera, manager of the Brandon St TAB in Wellington, where the lucky punter took his bet, said it couldn't have happened to a better customer.
"He's an NRL nut,'' she said.
"He closely studies the NRL form, and comes into the branch to do his homework before placing his bets. He's very astute, and he puts in the hard yards.''
The punter normally only takes head-to-head or winning team and margin bets, but he's taken to "using his nous'' to chase the bigger money on offer with multis and the re-launch of the rugby and league pools, with a guaranteed pool of $100,000.
